drivers/net/netconsole.c:99: warning: initialization from incompatible pointer type
<perrye@linuxmail.org>
[PATCH] I2C: i2c-voodoo3.c needs I2C_ADAP_CLASS_TV_ANALOG
The Voodoo3 i2c bus has either a bt869 tv-out chip, or also a tv tuner,
decoder and msp3400. Without I2C_ADAP_CLASS_TV_ANALOG, the i2c clients
would have to do a strcmp of the adapter name to distiguish between the
i2c and ddc adapters. Yes, they should be able to tell if the chip at a
given address is what they are looking for, but in the case of the v3tv
module, which is the v4l device, in the 2.4 kerenl I've got it set to
create a dummy client, and the strcmp is the only way to distinguish the
i2c from the ddc. In the 2.6 kernel, class can be defined, simplifying
things for the v3tv module.

<khali@linux-fr.org>
[PATCH] I2C: New chip driver ported: lm80
Here is a port for the lm80 driver, which supports LM80 chips by
National Semiconductor. The port is mostly the work of Tiago Sousa,
which I reviewed and polished as necessary.
<bunk@fs.tum.de>
[PATCH] I2C: update I2C help text
VIDEO_BT848 selects I2C_ALGOBIT.
<dsaxena@plexity.net>
[PATCH] I2C: Support for IXP42x GPIO-based I2C
Following is an updated patch to add support for using the GPIO lines
on an Intel IXP42x SOC for I2C. Changes since last patch include:
- Cleanups as per Jean Delvare's comments
- Rename functions as 42x instead of 425
- Change the comments at the top of the file to better reflect the
purpose of this driver.
This code has been tested with the eeprom client driver and worked
w/o any problems.

[PATCH] I2C: fix space in message
BTW, I found something to be fixed in i2c-core:
<khali@linux-fr.org>
[PATCH] I2C: fix mor rmmod oopses
> Oh nevermind, that's just a dumb driver. It's doing a release_region
> on memory it didn't get. Stupid, stupid, stupid...
While we're at it, what about fixing two other drivers that obviously
have the same problem?
(BTW I didn't get an oops as I tried reproducing the problem, only a
"Trying to free nonexistent resource" in dmesg.)
<khali@linux-fr.org>
[PATCH] I2C: Lowercase chips name
This patch brings the name field of adm1021.c, it87.c and via686a.c in
conformance with the defined standard ("all lowercase, as simple as the
driver name itself").
<khali@linux-fr.org>
[PATCH] I2C: fix Hangs with w83781d
Here is a patch for the w83781d driver that prevents register bits from
being arbitrary changed when we force temp2/3 to comparator mode. Keith
Duthie had been reporting various problems with that driver and finally
found that this arbitrary change was the cause of them. He also tested
this patch, which he confirmed to work.
<khali@linux-fr.org>
[PATCH] I2C: fix it87 sensor type
Here comes a patch by Takeru Komoriya which fixes the way the it87
driver handles temperature sensor types selection.
* Use the same values as the CVS driver and sensors program.
* Better comments.
* Get rid of the old setting method (already gone in CVS).
* Handle invalid values correctly.
<khali@linux-fr.org>
[PATCH] I2C: fix another oops in i2c-core with debug
Some times ago, you fixed an oops in i2c-core when debugging is enabled:
http://marc.theaimsgroup.com/?l=linux-kernel&m=107585749612115&w=2
Looks like you missed that second one:
<khali@linux-fr.org>
[PATCH] I2C: Remove asb100 support from w83781d
Now that we have a separate asb100 driver, we can remove the (bad)
support of it from the w83781d driver. Following patch does this. I've
already cleaned this up in our CVS repository.
<khali@linux-fr.org>
[PATCH] I2C: update for sysfs-interface documentation
<khali@linux-fr.org>
[PATCH] I2C: rename sysfs files, part 1 of 2
Here it is. The associated libsensors patch is here:
http://jdelvare.net1.nerim.net/sensors/libsensors-sysfs-names-1.diff
(not applied yet, on purpose)
<khali@linux-fr.org>
[PATCH] I2C: rename sysfs files, part 2 of 2
Here is the second step of my sysfs renaming plan.
This one does the following renames (as I already announced on the
LKML):
temp<n>_hyst -> temp<n>_max_hyst or temp<n>_crit_hyst
sensor<n> -> temp<n>_type
pwm<n> -> fan<n>_pwm
pwm<n>_enable -> fan<n>_pwm_enable
vid -> in<n>_ref
The associated libsensors patch is here:
http://jdelvare.net1.nerim.net/sensors/libsensors-sysfs-names-2.diff
(not applied yet, on purpose)
Note that the w83781d part is a bit more complex, not only because it is
the only driver to require the 5 changes, but also because at some point
the macros assume that the internal variable names match the sysfs
names, so I had to change them too (better than rewriting the macros,
methinks).
For reference, here is the list of changes, by driver:
asb100:
hyst -> max_hyst (4)
pwm -> fan_pwm (1)
pwm_enable -> fan_pwm_enable (1)
vid -> in_ref (1)
fscher:
pwm -> fan_pwm (3)
gl518sm:
hyst -> max_hyst (1)
it87:
sensor -> temp_type (3)
lm75:
hyst -> max_hyst (1)
lm78:
hyst -> max_hyst (1)
vid -> in_ref (1)
lm85:
pwm -> fan_pwm (3)
pwm_enable -> fan_pwm_enable (3)
vid -> in_ref (1)
lm90:
hyst -> crit_hyst (2)
via686a:
hyst -> max_hyst (3)
w83781d:
hyst -> max_hyst (2)
sensor -> temp_type (3)
pwm -> fan_pwm (4)
pwm_enable -> fan_pwm_enable (1)
vid -> in_ref (1)
There's also a documentation update. There will be one more after that
(to make it more readable, no contents change), and a patch to lm83.c to
bring it to compliance with the (new) standard. (If you wonder why I did
not change it with the other drivers: because it was *already* not in
compliance with the old standard. There's some real work to do for this
one.)

[PATCH] SCSI: Recognize device type 0x0C
Device type 0x0C is RAID, so show it as such
<jeremy@sgi.com>
[PATCH] SCSI: remove some SGI devices from the device list
Some SGI RAID devices identify as being SCSI-3, so they don't need
to be in the scsi_static_device_list any more. I've tested to make
sure that all luns still show up in a sparse, large config.
So I'm proposing removing them. Thanks to hch for the suggestion.

[PATCH] I2C: add w83627hf driver
The following patch against kernel 2.6.3 adds the w83627hf driver,
I have ported from the 2.4 version.
Jean Delvare has asked me to send this patch to you for applying.
I have tested it on w83627thf. Mark Hoffman has reviewed the code
and has also tested it on w83627thf.
<alex.williamson@hp.com>
ia64: minor 2.6 sba_iommu update
This is a minor update to sba_iommu initialization code. I moved the
relaxed ordering to the zx1 specific init routine, those registers don't
do anything on sx1000. The iommu page size setup is more generalized on
ACPI ID, so the sx1000 specific init routine goes away. And the virtual
dma_mask on zx1 was tweaked a little to better reflect the memory
address space.

[PATCH] I2C: it87 reset option
I wrote a patch which adds reset option to the it87 driver talking
with Jean Delvare.
* Do not reset the registers unless users want to do because
resetting registers makes all fans go to full power and we can
usually rely on values set by BIOS
* Remove all limit initializations as they should be done from
user-space
* Better register mask for start of monitoring

Here's my attempt at a zx1_defconfig. I haven't checked it on many

I know are needed on the other boxes.

[PATCH] ia64: SAL cleanup
This patch reorganises sal.c and adds a small amount of new functionality.
- Introduce sal_revision to report what revision of the SAL spec is
supported by the system.
- Introduce sal_version to report what version of the vendor's SAL
implementation is present.
- Introduce SAL_VERSION_CODE to allow for easy comparisons.
- Print the version at boot, and remove the 'oem=' and 'vendor=' strings.
- Refactor ia64_sal_init() into several smaller functions.
- Delete the dead variables 'max' and 'min'.
- Stop printing the pal_proc and sal_proc entry addresses.
- Print "None" if there are no SAL platform features.

[PATCH] ia64: Add support for extended PCI config space
Support for extended config space on ia64.
- Add the new parameter 'type' to ia64_sal_pci_config_{read,write}
- Change callers to match.
- Don't check `value' for NULL -- drivers/pci/access.c guarantees it isn't.
- Make pci_sal_ops static.
- Add pci_sal_ext_ops.
- Introduce pci_set_sal_ops() as an arch_initcall to ensure the raw_pci_ops
get set before we walk the ACPI namespace to discover PCI root bridges

ia64: Move irq_enter()/irq_exit() from hardirq.h to irq_ia64.c. The work

that this is the Right Thing to do.

[PATCH] SCSI sysfs host name support
OK, let's export the proc_name then. It's some name that can be used

[PATCH] SCSI tape sysfs name fixes
- The sysfs directory names are changed from stxmy[n] to the names in
devices.txt. Below is an example for the first tape drive:
/sys/class/scsi_tape/
|-- nst0
|-- nst0a
|-- nst0l
|-- nst0m
|-- st0
|-- st0a
|-- st0l
`-- st0m
- Name generation for non-default number of modes fixed so that same
minors get same names even with different number of modes.
- devfs minor generation fixed to work with non-default number of modes
- The alignment requirement is printed in the line logged when a tape is
attached.

[PATCH] I2C: show adapter name in i2c-dev class directory to make it easier for userspace tools.
<jbarnes@sgi.com>
[PATCH] ia64: Don't assume iosapic interrupt controllers
Some ia64 machines don't use an iosapic interrupt controller (a
flagrant violation of the DIG64 spec), so don't assume it's there in
mca.c. Platforms that provide a ACPI_INTERRUPT_CPEI vector are
responsible for registering its interrupt controller type in platform
specific code, iosapic.c:iosapic_register_platform_intr() does this
for platforms with an iosapic where the CPEI vector is listed in the
ACPI namespace, and on sn2, all external interrupts are assigned the
irq_type_sn type, so this change of assumption should be safe.
<greg@kroah.com>
[PATCH] I2C: keep i2c-dev numbers in sync with i2c adapter numbers
This makes userspace tools easier to figure out which i2c-dev device is
assigned to which i2c adapter.
Yes, we can overflow the i2c dev array right now, but that would take a
lot of i2c adapter modprobe/rmmod cycles. That will be fixed up soon.

This is part of a patch series to clean up sound/core/Makefile in Linux

- Add SND_TIMER, SND_PCM, SND_HWDEP and SND_RAWMIDI configuration symbols.
These symbols select which modules in sound/core get built, building
snd-timer, snd-pcm, snd-hwdep and snd-rawmidi respectively.
- Add reverse dependencies (select) to select these symbols for core
components where necessary.
- Hide SND_OSSEMUL - we can select this when SND_MIXER_OSS, SND_PCM_OSS
or SND_SEQUENCER_OSS are selected automatically.
- Tweak Makefile to use these new symbols to build these modules.
- Since we now build appropriate modules for core components according
to the new configuration symbols, (eg, snd-timer if SND_SEQUENCER is
selected) we can delete these duplications.

[PATCH] SCSI Midlayer initiated START_UNIT
The ipr driver that is currently out for review talks to disk array devices
that require a START_UNIT prior to media ops, similar to normal scsi devices.
However, any time the adapter gets reset, these devices end up needing another
START_UNIT. This causes problems with the current error handling and these
devices get taken offline when this occurs. Attached is a patch which will
better handle these devices and issue a START_UNIT from the error handler
when appropriate.

SCSI: Make SPI transport attributes mutable
This adds the final missing piece to the transport attributes: A
published API by which they can be set and retrieved (SPI attributes
only). The sysfs field only appears writeable if the driver supplied a
set method in the attribute template, so unsettable attributes show up
as read only.
The consequence now is that the spi transport attribute class is no
longer a simple exported structure: the driver has to attach to the spi
transport class at module initialisation.
<jejb@mulgrave.(none)>
SCSI: implement transport attributes for 53c700
his patch moves the internal storage of the offset and period to the
transport class and adds methods to set them (there's no need for a get
method since the value in the transport class is exactly what the driver
believes the transport agreement to be).
You can see how this type of use of the transport class is supposed to
work: the driver now has init and exit routines attaching and releasing
the transport class (that's the reason for the Makefile perturbation
because it has to init before its users). The correct attributes are
set up in slave_configure() for negotiation and we now export the period
and offset setting functions.

[libata] Split up shared IO register locations into individual components
Most ATA host controllers follow a standard layout for the
ATA shadow registers, where command/status, error/feature, and
devctl/altstatus share a single bus I/O address, because one register
of each pair is read-only, and the other is write-only.
On the Vitesse/Intel chip, all registers are given distinction bus I/O
addresses, which necessitates changing the libata data structures
to cope with this. This simply involves storing a few more bus addresses.

[libata] misc fixes, and an export
* export ata_host_intr
* fix debugging printk
* the write of Device Control register, which occurs between

[PATCH] I2C: Cleanup fan_div in w83781d
Here is a proposed patch that cleanups the fan_div code from w83781d.
The original code was obviously taken from the 2.4 driver, but the way
things were done in 2.4 do not make any sense anymore (because we now
have a single value per interface file).
Since fan divisor bits are spread over three different regs with various
bitmask manipulations, I don't think it makes much sense to have a
single function as we do in most other cases. Having three different
functions makes more sense, although they are of course similar. The
size increment is only 581 bytes, I don't think its a problem since it
also makes the code much more efficient and readable too IMHO.
I agree that the original code was working - it was simply doing far too
much work each time one would want to change a fan divisor.
Originally, I took a look at the code because I wanted to fix the fact
that changing fan divisors breaks fan mins. But it looked like a good
cleanup before doing that was required. Once this patch will have been
accepted, I'll work on the other one.
I've tested my patch successfully on a W83781D and an AS99127F rev.1.
Note that this means that one part of the code wasn't tested, because
these are the two chips of the family that do not support divisors
greater than 8. If anyone can test it, please do.

[ACPI] fix printk and build warning from previous csets

[PATCH] x86-64 merge for 2.6.4
The biggest new feature is fixed 32bit vsyscall (SYSCALL+SYSENTER)
support, mostly from Jakub Jelinek. This increases 32bit syscall
performance greatly (latency halved and better). The SYSENTER for Intel
support required some infrastructure changes, but seems to work now too.
The 64bit vsyscall vtime() just references xtime.tv_sec now. This
should make it a lot faster too.
A fix for some Intel IA32e systems. Also a few long standing bugs in
NMI like exception handlers were fixed.
And a lot of other bug fixes.
Full changeLog:
- Clean up 32bit address room limit handling, fix 3gb personality
- Move memcpy_{from,to}io export to ksyms.c file. This seems to work
around a toolchain bug (Andreas Gruenbacher)
- Update defconfig
- ACPI merges from i386 (SBF should work now, acpi=strict)
- Implement mmconfig support based on i386 code (untested)
- Fix i386/x86-64 pci source file sharing
- Implement ptrace access for 32bit vsyscall page
- Always initialize all 32bit SYSENTER/SYSCALL MSRs.
- Export run time cache line size to generic kernel
- Remove explicit CPUID in ia32 syscall code
- Fill in most of boot_cpu_data early
- Remove unused PER_LINUX32 setup
- Fix syscall trace in fast 32bit calls (Suresh B. Siddha)
- Tighten first line of the oops again.
- Set up ptrace registers correctly for debug,ss,double fault exceptions
- Fix 64bit bug in sys_time64
- Optimize time syscall/vsyscall to only read xtime
- Fix csum_partial_copy_nocheck
- Remove last traces of FPU emulation

- Harden exception stack entries (#SS,#NMI,#MC,#DF,#DB) against bogus GS
- Use an exception stack for machine checks
- Handle TIF_SINGLESTEP properly in kernel exit
- Add exception stack for debug handler
- Disable X86_HT for Opteron optimized builds because it pulls in ACPI_BOOT
- Fix CONFIG_ACPI_BOOT compilation without CONFIG_ACPI
- Fix eflags handling in SYSENTER path (Jakub Jelinek)
- Use atomic counter for enable/disable_hlt
- Support 32bit SYSENTER vsyscall too (Jakub Jelinek)
- Don't redefine Dprintk
- Change some cpu/apic id arrays to char
- Support arbitary cpu<->apicid in hard_smp_processor_id (Surresh B Sidda)
- Move K8 erratum #100 workaround into slow path of page fault handler.

ia64: don't unmask iosapic interrupts by default
In ia64 kernel, IOSAPIC's RTEs for PCI interrupts are unmasked at the

If some PCI devices without device driver generate interrupts, interrupts
are generated repeatedly because these interrupt requests are never
cleared. I think RTEs for PCI interrupts should be unmasked by device
driver. This patch fixes the problem.

[PATCH] user data -> request mapping
This patch allows you to map a request with user data for io, similarly
to what you can do with bio_map_user() already to a bio. However, this

[PATCH] fix ppc64 in kernel syscalls
Thanks to some great debugging work by Olaf Hering and Marcus Meissner
it has been noticed that the current ppc64 syscall code is corrupting

unusable in the kernel.
Since we had to reinstate the inline syscall code we can go back to
using it for those few syscalls that we call. Especially now with
Randy's syscall prototype cleanup we should be calling them directly
but we can do that sometime later.

[PATCH] adaptive lazy readahead
From: Suparna Bhattacharya <suparna@in.ibm.com>
From: Ram Pai <linuxram@us.ibm.com>
Pipelined readahead behaviour is suitable for sequential reads, but not for
large random reads (typical of database workloads), where lazy readahead
provides a big performance boost.
One option (suggested by Andrew Morton) would be to have the application
pass hints to turn off readahead by setting the readahead window to zero
using posix_fadvise64(POSIX_FADV_RANDOM), and to special-case that in
do_generic_mapping_read to completely bypass the readahead logic and
instead read in all the pages needed directly.
This was the idea I started with. But then I thought, we can do a still
better job ? How about adapting the readahead algorithm to lazy-read or
non-lazy-read based on the past i/o patterns ?
The overall idea is to keep track of average number of contiguous pages
accessed in a file. If the average at any given time is above ra->pages
the pattern is sequential. If not the pattern is random. If pattern is
sequential do non-lazy-readahead( read as soon as the first page in the
active window is touched) else do lazy-readahead.
I have studied the behaviour of this patch using my user-level simulator.
It adapts pretty well.
Note from Suparna: This appears to bring streaming AIO read performance for
large (64KB) random AIO reads back to sane values (since the lazy readahead
backout in the mainline).

[PATCH] time interpolator fix
From: john stultz <johnstul@us.ibm.com>
In developing the ia64-cyclone patch, which implements a cyclone based time
interpolator, I found the following bug which could cause time
inconsistencies.
In update_wall_time_one_tick(), which is called each timer interrupt, we
call time_interpolator_update(delta_nsec) where delta_nsec is approximately
NSEC_PER_SEC/HZ. This directly correlates with the changes to xtime which
occurs in update_wall_time_one_tick().
However in update_wall_time(), on a second overflow, we again call
time_interpolator_update(NSEC_PER_SEC). However while the components of
xtime are being changed, the overall value of xtime does not (nsec is
decremented NSEC_PER_SEC and sec is incremented). Thus this call to
time_interpolator_update is incorrect.
This patch removes the incorrect call to time_interpolator_update and was
found to resolve the time inconsistencies I had seen while developing the
ia64-cyclone patch.

[PATCH] i386 very early memory detection cleanup patch
From: "H. Peter Anvin" <hpa@zytor.com>
This patch cleans up the very early memory setup on the i386 platform. In
particular, it removes the hard-coded 8 MB limit completely by dynamically
creating the early-boot pagetables rather than having them hard coded.
While I was at it, I changed head.S so that it always sets up a local GDT;
this means among other things that SMP and VISWS are no longer special
cases, and is conceptually cleaner to boot. The VISWS people have
confirmed it works on VISWS.
It also uses a separate entrypoint for non-boot processors since this is
completely kernel-internal anyway. This eliminates the need to set %bx on
boot. (If you think this is a bad idea I can eliminate this change; it
just seemed cleaner to me to do it this way.)
Additionally, zero bss with rep;stosl rather that rep;stosb.

[PATCH] LOOP_CHANGE_FD ioctl
From: Arjan van de Ven <arjanv@redhat.com>
The patch below (written by Al Viro) solves a nasty chicken-and-egg issue
for operating system installers (well at least anaconda but the problem
domain is not exclusive to that)
The basic problem is this:
- The small first stage installer locates the image file of the second
stage installer (which has X and all the graphical stuff); this image can
be on the same CD, but it can come via NFS, http or ftp or ... as well.
- The first stage installer loop-back mounts this image and gives control
to the second stage installer by calling some binary there.
- The graphical installer then asks the user all those questions and
starts installing packages. Again the packages can come from the CD but
also from NFS or http or ...
Now in case of a CD install, once all requested packages from the first CD
are installed, the installer wants to unmount and eject the CD and prompt
the user to put CD 2 in....... EXCEPT that the unmount can't work since
the installer is actually running from a loopback mount of this cd.
The solution is a "LOOP_CHANGE_FD" ioctl, where basically the installer
copies the image to the harddisk (which can only be done late since only
late the target harddisk is mkfs'd) and then magically switches the backing
store FD from underneath the loop device to the one on the target harddisk
(and thus unbusying the CD mount).
This is obviously only allowed if the size of the new image is identical
and if the loop image is read-only in the first place. It's the
responsibility of root to make sure the contents is the same (but that's of
the give-root-enough-rope kind)
<akpm@osdl.org>
[PATCH] loop setup race fix
From: Chris Mason <mason@suse.com>
There's a race in loopback setup, it's easiest to trigger with one or more
procs doing loopback mounts at the same time. The problem is that
fs/block_dev.c:do_open() only calls bdev_set_size on the first open.
Picture two procs:
proc1: mount -o loop file1 mnt1
proc2: mount -o loop file2 mnt2
proc1 proc2
open /dev/loop0 # bd_openers now 1
do_open
bd_set_size(bdev, 0) # loop unbound, so bdev size is 0
open /dev/loop0 # bd_openers now 2
loop_set_fd # disk capacity now correct, but
# bdev not updated
mount /dev/loop0 /mnt
do_open
Because bd_openers != 0 for the last do_open, bd_set_size is not called
again and a size of 0 is used. This eventually leads to an oops when the
loop device is unmounted, because fsync_bdev calls block_write_full_page
who decides every page on the block device is outside i_size and unmaps
them.
When ext2 or reiserfs try to sync a metadata buffer, we get an oops on
because the buffers are no longer mapped.
The patch below changes loop_set_fd and loop_clr_fd to also manipulate the
size of the block device, which fixes things for me.

[PATCH] kbuild: fix usage with directories containing '.o'
From: Sam Ravnborg <sam@ravnborg.org>
From: Daniel Mack <daniel@zonque.org>, me

b) when someone names a kernel directory so it contains ".o". One
example is drivers/scsi/aic.ok/...
case b) was triggered by renaming the directory for aic7xxx, and modifying
Makefile and Kconfig. This caused make modules to fail.

code was running without the semaphore array spinlock. If the array
disappeared, then it will return without holding a lock. find_undo calls
sem_revalidate and then sem_unlock, even if sem_revalidate failed. The
sem_unlock call must be removed.
Mingming Cao reported a spinlock deadlock with sysv semaphores. A
superflous unlock doesn't explain the deadlock, but it's obviously a bug.

[PATCH] Remove arbitrary #acl entries limits on ext[23] when reading
From: Andreas Gruenbacher <agruen@suse.de>
Remove the arbitrary limit of 32 ACL entries on ext[23] when reading from
disk. This change is backward compatible; we need to have this change in
to be able to also allow writing big ACLs.
The second patch that removes the ACL entry limit for writes is not
included. I don't want to push that patch now, because large ACLs would
cause 2.4 and current 2.6 kernels to fail. My plan is to remove the second
limit later, in a half-year or year or so.

[PATCH] fadvise(POSIX_FADV_DONTNEED) fixups
From: WU Fengguang <wfg@mail.ustc.edu.cn>
- In sys_fadvise64_64(): if the start and/or end offsets do not fall on

is better to preserve needed memory than to not shoot down unneeded memory.

worth of pages each time around, even if that went beyond the part of the
file which the caller asked to be invalidated. Fix that up.

[PATCH] Fix reading the last block on a bdev
From: Chris Mason <mason@suse.com>
This patch fixes a problem we're hitting on ia64 with page sizes > 4k.
When the page size is greater than the block size, and parts of the page
fall past the end of the device, readpage will fail because
blkdev_get_block returns -EIO for blocks past i_size.
The attached patch changes blkdev_get_block to return holes when reading
past the end of the device, which allows us to read that last valid 4k
block and then fill the rest of the page with zeros. Writes will still
fail with -EIO.

[PATCH] EDD: Get Legacy Parameters
From: Matt Domsch <Matt_Domsch@dell.com>
Patch below from Patrick J. LoPresti and myself. Patrick describes:
Why this patch? The problem is that the legacy BIOS interface
(INT13/AH=3D08) for querying the disk geometry returns different values
than the extended INT13 interface which the EDD code currently uses. This
is because the legacy interface only provides a 10-bit cylinder field, so
modern BIOSes "lie" about the head/sector counts in order to make more of
the disk visible within the first 1024 cylinders.
Many non-Linux applications, including the stock Windows boot loader, DOS
fdisk, etc., rely upon the legacy interface and geometry. So it is useful
to be able to obtain the legacy values from a running Linux kernel.
What this patch does is to add new entries under
/sys/firmware/edd/int13_devXX named "legacy_cylinders", "legacy_heads", and
"legacy_sectors". These provide the geometry given by the legacy
INT13/AH=3D08 BIOS interface, just like the current "default_cylinders"
etc. provide the the geometry given by the INT13/AH=3D48 interface.
Without this patch, I cannot use Linux to partition a drive and install
Windows, which happens to be my application.
- Pat
http://unattended.sourceforge.net/
In addition, this adds two buggy BIOS workarounds in the EDD int13
calls as suggested by Ralf Brown's interrupt list.
I'm also interested in moving this code out of arch/i386/kernel/edd.c and
include/asm-i386/edd.h, as I believe it is applicable on x86-64 as well.
However, there's no good place under drivers/ to put edd.c when it's not
tied to a bus, but to several CPU architectures and their firmwares...
Maybe a new directory drivers/firmware?

[PATCH] fix raid0 readahead size
From: Arjan van de Ven <arjanv@redhat.com>
Readahead of raid0 was suboptimal; it read only 1 stride ahead. The
problem with this is that while it will keep all spindles busy, it will not
actually manage to make larger IO's, eg each disk would just do the chunk
size IO. Doing at least 2 chunks is more than appropriate so that each
spindle will get a chance to merge IO's.

From: James Simmons <jsimmons@infradead.org>,
Kronos <kronos@kronoz.cjb.net>
Various fixes and enhancements to the monitor hardware detection code. The
only driver that uses it is the radeon driver.
Old EDID parsing code was very verbose, half of the patch address this (ie.
print lots of stuff iff DEBUG). The other big change is the FB_MODE_IS_*
stuff: we really need a way to know the origin of a video mode. In this way
we can select video mode that comes from EDID instead of VESA or GTF.
Drivers other than radeonfb won't be affected because they cannot (yet) get
EDID from the monitor and don't use EDID related code.

[PATCH] mm/vmscan.c: remove unused priority argument.

<akpm@osdl.org>
[PATCH] kswapd throttling fixes
The logic in balance_pgdat() is all bollixed up.
- the incoming arg `nr_pages' should be used to determine if we're being
asked to free a specific number of pages, not `to_free'.
- local variable `to_free' is not appropriate for the determination of
whether we failed to bring all zones to appropriate free pages levels.
Fix this by correctly calculating `all_zones_ok' and then use
all_zones_ok to determine whether we need to throttle kswapd.
So the logic now is:
for (increasing priority) {
all_zones_ok = 1;
for (all zones) {
to_reclaim = number of pages to try to reclaim
from this zone;
max_scan = number of pages to scan in this pass
(gets larger as `priority' decreases)
/*
* set `reclaimed' to the number of pages which were
* actually freed up
*/
reclaimed = scan(max_scan pages);
reclaimed += shrink_slab();
to_free -= reclaimed; /* for the `nr_pages>0' case */
/*
* If this scan failed to reclaim `to_reclaim' or more
* pages, we're getting into trouble. Need to scan
* some more, and throttle kswapd. Note that this
* zone may now have sufficient free pages due to
* freeing activity by some other process. That's
* OK - we'll pick that info up on the next pass
* through the loop.
*/
if (reclaimed < to_reclaim)
all_zones_ok = 0;
}
if (to_free > 0)
continue; /* swsusp: need to do more work */
if (all_zones_ok)
break; /* kswapd is done */
/*
* OK, kswapd is getting into trouble. Take a nap, then take
* another pass across the zones.

[PATCH] vm: scan slab in response to highmem scanning
The patch which went in six months or so back which said "only reclaim slab
if we're scanning lowmem pagecache" was wrong. I must have been asleep at
the time.
We do need to scan slab in response to highmem page reclaim as well. Because
all the math is based around the total amount of memory in the machine, and
we know that if we're performing highmem page reclaim then the lower zones
have no free memory.
<akpm@osdl.org>
[PATCH] vmscan: zone balancing fix
We currently have a problem with the balancing of reclaim between zones: much
more reclaim happens against highmem than against lowmem.
This patch partially fixes this by changing the direct reclaim path so it
does not bale out of the zone walk after having reclaimed sufficient pages
from highmem: go on to reclaim from lowmem regardless of how many pages we
reclaimed from lowmem.
<akpm@osdl.org>
[PATCH] vmscan: drive everything via nr_to_scan
Page reclaim is currently a bit schitzo: sometimes we say "go and scan this
many pages and tell me how many pages were freed" and at other times we say
"go and scan this many pages, but stop if you freed this many".
It makes the logic harder to control and to understand. This patch coverts
everything into the "go and scan this many pages and tell me how many pages
were freed" model.
It doesn't seem to affect performance much either way.
<akpm@osdl.org>
[PATCH] Balance inter-zone scan rates
When page reclaim is working out how many pages to san in a zone (max-scan)
it presently rounds that number up if it looks too small - for work batching.
Problem is, this can result in excessive scanning against small zones which
have few inactive pages. So remove it.
Not that it is possible for max_scan to be zero. That's OK - it'll become
non-zero as the priority increases.
<akpm@osdl.org>
[PATCH] vmscan: avoid bogus throttling
- If max_scan evaluates to zero due to a very small inactive list and high
`priority' numbers, we don't want to thrlttle yet.
- In balance_pgdat(), we may end up not scanning any pages because all
zones happened to be above pages_high. Avoid throttling in this case too.
<akpm@osdl.org>
[PATCH] kswapd: avoid unnecessary reclaiming from higher zones
Currently kswapd walks across all zones in dma->normal->highmem order,
performing proportional scanning until all zones are OK. This means that
pressure against ZONE_NORMAL causes unnecessary reclaim of ZONE_HIGHMEM.
To fix that up we change kswapd so that it walks the zones in the
high->normal->dma direction, skipping zones which are OK. Once it encounters
a zone which needs some reclaim kswapd will perform proportional scanning
against that zone as well as all the succeeding lower zones.
We scan the lower zones even if they have sufficient free pages. This is
because
a) the lower zone may be above pages_high, but because of the incremental
min, the lower zone may still not be eligible for allocations. That's bad
because cache in that lower zone will then not be scanned at the correct
rate.
b) pages in this lower zone are usable for allocations against the higher
zone. So we do want to san all the relevant zones at an equal rate.
<akpm@osdl.org>
[PATCH] kswapd: fix lumpy page reclaim
As kswapd is now scanning zones in the highmem->normal->dma direction it can
get into competition with the page allocator: kswapd keep on trying to free
pages from highmem, then kswapd moves onto lowmem. By the time kswapd has
done proportional scanning in lowmem, someone has come in and allocated a few
pages from highmem. So kswapd goes back and frees some highmem, then some
lowmem again. But nobody has allocated any lowmem yet. So we keep on and on
scanning lowmem in response to highmem page allocations.
With a simple `dd' on a 1G box we get:

[PATCH] fix the kswapd zone scanning algorithm
This removes a vestige of the old algorithm. We don't want to skip zones if

[PATCH] vmscan: less throttling of page allocators and kswapd

[PATCH] vmscan: batch up inactive list scanning work
From: Nick Piggin <piggin@cyberone.com.au>
Use a "refill_counter" for inactive list scanning, similar to the one used
for active list scanning. This batches up scanning now that we precisely
balance ratios, and don't round up the amount to be done.
No observed benefits, but I imagine it would lower the acquisition
frequency of the lru locks in some cases, and make codepaths more efficient
in general due to cache niceness.

[PATCH] vm: balance inactive zone refill rates
The current refill logic in refill_inactive_zone() takes an arbitrarily large
number of pages and chops it down to SWAP_CLUSTER_MAX*4, regardless of the
size of the zone.
This has the effect of reducing the amount of refilling of large zones
proportionately much more than of small zones.
We made this change in may 2003 and I'm damned if I remember why. let's put
it back so we don't truncate the refill count and see what happens.

MPT Fusion driver 3.01.01 update
From: Moore, Eric Dean <Emoore@lsil.com>
This is an update for the MPT Fusion drivers 2.6 kernel.
Version 3.01.01.
This is a fix for poor performance in RAID Volumes.
The dvStatus was being cleared for hidden physical disks
when mptscsih_slave_destroy is called.
Also, I have fixed the warning comming from mptscsih_reset_timeouts.

[PATCH] sym2 2.1.18i
- Correct a typo "mvram" -> "nvram".
- Re-do the PQS/PDS support which I'd #if 0 out. Should even work on
multiple-domain boxes now ;-)
- Move all the nvram definitions to sym_nvram.h (from Gerard's 2.1.19-pre3)
- hcb_p -> struct sym_hcb *
- sdev_p -> struct sym_device *
- Delete a lot of unused macros from sym_misc.h
- Move READ_BARRIER and WRITE_BARRIER definitions to sym_glue.h
- SYM_CONF_NVRAM_WRITE_SUPPORT (from Gerard's 2.1.19-pre3). Not enabled
yet.
- Fix some -W warnings (some courtesy of Adrian Bunk).

[PATCH] add device quiescing to the SCSI API
This patch adds the ability to quiesce a SCSI device. The idea is that
user issued commands (including filesystem ones) would get blocked,
while mid-layer and device issued ones would be allowed to proceed.
This is for things like Domain Validation which like to operate on an
otherwise quiet device.
There is one big change: to get all of this to happen correctly,
scsi_do_req() has to queue on the *head* of the request queue, not the
tail as it was doing previously. The reason is that deferred requests
block the queue, so anything needing executing after a deferred request
has to go in front of it. I don't think there are any untoward
consequences of this.

[PATCH] more SPI transport attribute updates
This does three things
- Fix the signedness of the bit attributes (otherwise they show up as -1
when on, not 1)
- Make the period adjust to the closest value rather than ignoring
values it doesn't understand.
- Add a visibility field to attributes, so drivers can get rid of
attributes they're never going to care about
<James.Bottomley@steeleye.com>
[PATCH] update the 53c700 use of transport attributes
This patch just brings it up to date with the previous transport
attribute patch, moving it to the model where it sets the min/max of the
attribute if asked for something outside its range. It also only makes
period and offset visible (it doesn't care about any of the others).

[PATCH] cdev 1/2: Eliminate /sys/cdev
This is the first of two patches designed to make life easier for authors
of device driver books - and, with luck, driver authors too.
/sys/cdev is, according to Al, a mistake which was never really meant to
exist. I believe nothing uses it currently - there isn't a whole lot there
to use. Its existence takes up system resources, and also requires drivers
to deal with the cdev's embedded kobject in their failure paths. The
following patch (against 2.6.4) makes it all go away.
OK, almost all. We have to keep (but not register) cdev_subsys because
it's rwsem is needed to control access to cdev_map.
<corbet@lwn.net>
[PATCH] cdev 2/2: hide cdev->kobj
The existing cdev interface requires users to deal with the embedded
kobject in two places:
- The kobject name field must be set before adding the cdev, and
- Should cdev_add() fail, a call to kobject_put() is required.
IMO, this exposure of the embedded kobject makes the interface more brittle
and harder to understand. It's also unnecessary. With the removal of
/sys/cdev, a call to cdev_del() will nicely replace kobject_put(), and the
name setting is easily wrapped.
This is against 2.6.4, but depends on the /sys/cdev removal patch.
<greg@kroah.com>
remove cdev_set_name completely as it is not needed.

[ACPI] SMP poweroff (David Shaohua Li)
http://bugzilla.kernel.org/show_bug.cgi?id=1141
<len.brown@intel.com>
[ACPI] ACPICA 20040311 from Bob Moore
Fixed a problem where errors occurring during the parse phase of control
method execution did not abort cleanly. For example, objects created
and installed in the namespace were not deleted. This caused all
subsequent invocations of the method to return the AE_ALREADY_EXISTS
exception.
Implemented a mechanism to force a control method to "Serialized"
execution if the method attempts to create namespace objects.
(The root of the AE_ALREADY_EXISTS problem.)
Implemented support for the predefined _OSI "internal" control method.
Initial supported strings are "Linux", "Windows 2000", "Windows 2001",
and "Windows 2001.1", and can be easily upgraded for new strings as
necessary. This feature allows Linux to execute
the fully tested, "Windows" code path through the ASL code
Global Lock Support: Now allows multiple acquires and releases with any
internal thread. Removed concept of "owning thread" for this special
mutex.
Fixed two functions that were inappropriately declaring large objects on
the CPU stack: ps_parse_loop() and ns_evaluate_relative().
Reduces the stack usage during method execution considerably.
Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the
S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.
Fixed a problem where acpi_ev_gpe_detect() would fault
if there were no GPEs defined on the machine.
Implemented two runtime options: One to force all control method
execution to "Serialized" to mimic Windows behavior, another to disable
_OSI support if it causes problems on a given machine.

<James.Bottomley@steeleye.com>
[PATCH] Add Domain Validation to the SPI transport class
Domain Validation is a fairly essential element to the SCSI Parallel
Interface (although if you look very few drivers actually do it). The
premise is that the Parallel Bus, being a transmission line, might not
be correctly tuned to the transfers you want do perform. DV probes the
parameters of the transport until it finds a setting that works (for the
interested, see http://www.t10.org/ftp/t10/drafts/sdv/sdv-r08b.pdf)
The current code employs rather simplistic DV heuristics, although those
can be improved over time. The change in scsi_scan.c is so that DV may
be done easily from the slave_configure routine, which is the most
natural place to begin.

[PATCH] Fix removable USB drive oops
The actual problem reported was because there wasn't a corresponding
check on transport_classdev.class in the unregister.
However, on closer inspection I also turned up a nasty thinko in the
reference counting. For reasons best known to the class code authors,
class devices have to obtain their own references to the devices they're
attached to which they release again in their .release routines, so you
have to remember to do a get_device() in the correct place after the
class_device_add(). I put comments in the code so that, hopefully, we
can avoid the problem in future.

[WATCHDOG] v2.6.4 pcwd_pci-v1.00_20040313-patch
Two small fixes:
* Make cards_found a global variable so that if we remove the
pci device we can count down.
* If we can't find a correct I/O address for the card, then we
should disable the card again.
<wim@iguana.be>
WATCHDOG] v2.6.4 wdt977-v0.03-patch
Version 0.03 of wdt977.c - Changes that were made are:
* Extract the stop code in a seperate function (wdt977_stop)
* Extract the start code in a seperate function (wdt977_start)
* Rename kick_wdog to wdt977_keepalive for consistency
* Extract the watchdog's status code to a seperate function (wdt977_get_status)
* Change the way we deal with the watchdog timeout:
Up till now we used timeoutM (in minutes) as the correct value and then
calculated timeout as being timeoutM*60 or *timeoutM*120 (depending on
wether or not we have the netwinder hardware bug).
From now on timeout is the correct value and we calculate timeoutM out
of it. Because of this we start with checking wether or not we have a
correct timeout value (if not we reset it to the default value) and we
automatically calculate timeoutM. Each time we change timeout with a
correct timeout value, we recalculate timeoutM.
* Extended ioctl code with WDIOC_SETOPTIONS and updated the watchdog_info structure
* Added notifier support
Code has been tested by Woody

RPC: When trying to reconnect to a TCP port, try to bind() to the last used port number
in order to ensure that the servers NFS replay cache recognizes this as being the
same mount as before.
<trond.myklebust@fys.uio.no>
RPC,NFSv2/v3/v4: Ensure that xprt_create_proto() and rpc_create_client() return

NFSv2/v3/v4: Parenthesize #defines in nfs?xdr.c. Fix an off-by-one error on the value
of compound_decode_hdr_maxsz.
NFSv4: fix a printk() typo (spotted by Linda Dunaphant).
NFSv4: Ensure that nfs4_open_reclaim() copies the value of the new stateid back into
the shared nfsv4 state structure.
NFSv4: Don't leak NFS4ERR_WRONGSEC errors back into nfs_lookup().
RPC,NFS,Lockd: Mark the debugging code as "unlikely" so that gcc moves it out of the

NFSv2/v3 locking: Patch by Patrice Dumas to ensure that the server index blocks uniquely
by using the client address in addition to the value of the NLM cookie field.
<trond.myklebust@fys.uio.no>
NFSv2/v3 locking: A patch to ensure that blocks which are not going to time out
are placed last on the ordered list nlm_block (problem reported by Olaf
Kirch).
<trond.myklebust@fys.uio.no>
RPC,NFSv3: remove the redundant "memset()" in call_encode(). Fix up the only places
where this causes a padding error: xdr_encode_fhandle() and unx_marshal()
<trond.myklebust@fys.uio.no>
RPC: patch by Chuck Lever to make the number of RPC slots a tunable parameter.
This is wanted in order to allow the NFS client to send more requests before

This is mainly useful if you have a WAN and want to ensure that the bandwidth
is being used efficiently.

NFS: From the suse kenrel RPM: handle ENOMEM from nfs_fhget().
<trond.myklebust@fys.uio.no>
From: <martin@meltin.net>
Forward-port from 2.4:
The following patch pulls an NFS server IP address off root_server_path
(handed out via the DHCP root-path option), if it is present. For example,
you can do this sort of thing in dhcpd.conf:
root-path = 192.168.1.33:/tftpboot/yip.zImage
This lets you mount your root filesystem off a different machine than you
booted from, without needing to use kernel command-line parameters.
The patch appears to be backwards compatible.
RFC2132 says this about the root-path option:
This option specifies the path-name that contains the client's root
disk. The path is formatted as a character string consisting of
characters from the NVT ASCII character set.
This is sufficiently vague to allow the path-name to include an IP-address.
Also, I found some documentation for FreeBSD saying it does this too, so it
must be right, because those FreeBSD guys are really smart... :-)
The only downside of the patch is that the summary that ipconfig prints can
be a little odd when the kernel command line overrides whatever ipconfig gets
from (say) DHCP. The address from the kernel command line seems to get
stripped off early, so ipconfig reports it, but it doesn't report the kernel
command line NFS path, since that's handled a bit later... This small
cosmetic problem looks difficult to "fix" without rewriting quite a bit of
stuff...
