[PATCH] powerpc: windfarm shall request it's sub modules
The windfarm code, in it's current incarnation, uses request_module() to
load the various submodules it needs for a given platform so that only
the main platform control module needs to be modprobed. However, it was
missing various bits. This fixes it. In the future, we'll use some
hotplug mecanisms to try to get all of this auto-loaded on the platforms
where it matters but that isn't ready yet.

[PATCH] Use delayed disable mode of ioapic edge triggered interrupts
Komuro reports that ISA interrupts do not work after a disable_irq(),
causing some PCMCIA drivers to not work, with messages like
eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx
eth0: found link beat
eth0: autonegotiation complete: 100baseT-FD selected
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
...
Linus Torvalds <torvalds@osdl.org> said:
"Now, edge-triggered interrupts are a _lot_ harder to mask, because the
Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic
_before_ the mask logic, so if a edge happens _while_ the device is
masked, you'll never ever see the edge ever again (unmasking will not
cause a new edge, so you simply lost the interrupt).
So when you "mask" an edge-triggered IRQ, you can't really mask it at all,
because if you did that, you'd lose it forever if the IRQ comes in while
you masked it. Instead, we're supposed to leave it active, and set a flag,
and IF the IRQ comes in, we just remember it, and mask it at that point
instead, and then on unmasking, we have to replay it by sending a
self-IPI."
This trivial patch solves the problem.

Revert "[PATCH] fix Data Acess error in dup_fd"
This reverts commit 0130b0b32ee53dc7add773fcea984f6a26ef1da3.
Sergey Vlasov points out (and Vadim Lobanov concurs) that the bug it was
supposed to fix must be some unrelated memory corruption, and the "fix"
actually causes more problems:
"However, the new code does not look safe in all cases. If some other
task has opened more files while dup_fd() released oldf->file_lock, the
new code will update open_files to the new larger value. But newf was
allocated with the old smaller value of open_files, therefore subsequent
accesses to newf may try to write into unallocated memory."
so revert it.

[PATCH] libata: Convert from module_init to subsys_initcall
When building a monolithic kernel, the load order of drivers does not
work for SAS libata users, resulting in a kernel oops.
Convert libata to use subsys_initcall instead of module_init, which
ensures that libata gets loaded before any LLDD.
This is the same thing that scsi core does to solve the problem. The
load order problem was observed on ipr SAS adapters and should exist for
other SAS users as well.

[PATCH] hugetlb: check for brk() entering a hugepage region
Unlike mmap(), the codepath for brk() creates a vma without first checking
that it doesn't touch a region exclusively reserved for hugepages. On
powerpc, this can allow it to create a normal page vma in a hugepage
region, causing oopses and other badness.
Add a test to prevent this. With this patch, brk() will simply fail if it
attempts to move the break into a hugepage reserved region.

[PATCH] hugetlb: prepare_hugepage_range check offset too
(David:)
If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example,
because the given file offset is not hugepage aligned - then do_mmap_pgoff
will go to the unmap_and_free_vma backout path.
But at this stage the vma hasn't been marked as hugepage, and the backout path
will call unmap_region() on it. That will eventually call down to the
non-hugepage version of unmap_page_range(). On ppc64, at least, that will
cause serious problems if there are any existing hugepage pagetable entries in
the vicinity - for example if there are any other hugepage mappings under the
same PUD. unmap_page_range() will trigger a bad_pud() on the hugepage pud
entries. I suspect this will also cause bad problems on ia64, though I don't
have a machine to test it on.
(Hugh:)
prepare_hugepage_range() should check file offset alignment when it checks
virtual address and length, to stop MAP_FIXED with a bad huge offset from
unmapping before it fails further down. PowerPC should apply the same
prepare_hugepage_range alignment checks as ia64 and all the others do.
Then none of the alignment checks in hugetlbfs_file_mmap are required (nor
is the check for too small a mapping); but even so, move up setting of
VM_HUGETLB and add a comment to warn of what David Gibson discovered - if
hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region
when unwinding from error will go the non-huge way, which may cause bad
behaviour on architectures (powerpc and ia64) which segregate their huge
mappings into a separate region of the address space.

[PATCH] x86-64: Fix vgetcpu when CONFIG_HOTPLUG_CPU is disabled
The vgetcpu per CPU initialization previously relied on CPU hotplug
events for all CPUs to initialize the per CPU state. That only
worked only on kernels with CONFIG_HOTPLUG_CPU enabled. On the
others some CPUs didn't get their state initialized properly
and vgetcpu wouldn't work.
Change the initialization sequence to instead run in a normal
initcall (which runs after the normal CPU bootup) and initialize
all running CPUs there. Later hotplug CPUs are still handled
with an hotplug notifier.
This actually simplifies the code somewhat.

[PATCH] x86-64: setup saved_max_pfn correctly (kdump)
x86_64: setup saved_max_pfn correctly
2.6.19-rc4 has broken CONFIG_CRASH_DUMP support on x86_64. It is impossible
to read out the kernel contents from /proc/vmcore because saved_max_pfn is set
to zero instead of the max_pfn value before the user map is setup.
This happens because saved_max_pfn is initialized at parse_early_param() time,
and at this time no active regions have been registered. save_max_pfn is setup
from e820_end_of_ram(), more exact find_max_pfn_with_active_regions() which
returns 0 because no regions exist.
This patch fixes this by registering before and removing after the call
to e820_end_of_ram().

[PATCH] x86-64: shorten the x86_64 boot setup GDT to what the comment says
Stephen Tweedie, Herbert Xu, and myself have been struggling with a very
nasty bug in Xen. But it also pointed out a small bug in the x86_64
kernel boot setup.
The GDT limit being setup by the initial bzImage code when entering into
protected mode is way too big. The comment by the code states that the
size of the GDT is 2048, but the actual size being set up is much bigger
(32768). This happens simply because of one extra '0'.
Instead of setting up a 0x800 size, 0x8000 is set up. On bare metal this
is fine because the CPU wont load any segments unless they are
explicitly used. But unfortunately, this breaks Xen on vmx FV, since it
(for now) blindly loads all the segments into the VMCS if they are less
than the gdt limit. Since the real mode segments are around 0x3000, we are
getting junk into the VMCS and that later causes an exception.
Stephen Tweedie has written up a patch to fix the Xen side and will be
submitting that to those folks. But that doesn't excuse the GDT limit
being a magnitude too big.

libata: fix double-completion on error
A curious thing happens, however, when ata_qc_new_init fails to get
an ata_queued_cmd:
First, ata_qc_new_init handles the failure like this:
cmd->result = (DID_OK << 16) | (QUEUE_FULL << 1);
done(cmd);
Then, we return to ata_scsi_translate and do this:
err_mem:
cmd->result = (DID_ERROR << 16);
done(cmd);
It appears to me that first we set a status code indicating that we're
ok but the device queue is full and finish the command, but then
we blow away that status code and replace it with an error flag and
finish the command a second time! That does not seem to be desirable
behavior since we merely want the I/O to wait until a command slot
frees up, not send errors up the block layer.

IB/mad: Fix race between cancel and receive completion
When ib_cancel_mad() is called, it puts the canceled send on a list
and schedules a "flushed" callback from process context. However,
this leaves a window where a receive completion could be processed
before the send is fully flushed.
This is fine, except that ib_find_send_mad() will find the MAD and
return it to the receive processing, which results in the sender
getting both a successful receive and a "flushed" send completion for
the same request. Understandably, this confuses the sender, which is
expecting only one of these two callbacks, and leads to grief such as
a use-after-free in IPoIB.
Fix this by changing ib_find_send_mad() to return a send struct only
if the status is still successful (and not "flushed"). The search of
the send_list already had this check, so this patch just adds the same
check to the search of the wait_list.

[PATCH] SCSI core: always store >= 36 bytes of INQUIRY data
This patch (as810c) copies a minimum of 36 bytes of INQUIRY data, even if
the device claims that not all of them are valid. Often badly behaved
devices put plausible data in the Vendor, Product, and Revision strings but
set the Additional Length byte to a small value. Using potentially valid
data is certainly better than allocating a short buffer and then reading
beyond the end of it, which is what we do now.

[PATCH] Fix misrouted interrupts deadlocks
While testing kernel on machine with "irqpoll" option I've caught such a
lockup:
__do_IRQ()
spin_lock(&desc->lock);
desc->chip->ack(); /* IRQ is ACKed */
note_interrupt()
misrouted_irq()
handle_IRQ_event()
if (...)
local_irq_enable_in_hardirq();
/* interrupts are enabled from now */
...
__do_IRQ() /* same IRQ we've started from */
spin_lock(&desc->lock); /* LOCKUP */
Looking at misrouted_irq() code I've found that a potential deadlock like
this can also take place:
1CPU:
__do_IRQ()
spin_lock(&desc->lock); /* irq = A */
misrouted_irq()
for (i = 1; i < NR_IRQS; i++) {
spin_lock(&desc->lock); /* irq = B */
if (desc->status & IRQ_INPROGRESS) {
2CPU:
__do_IRQ()
spin_lock(&desc->lock); /* irq = B */
misrouted_irq()
for (i = 1; i < NR_IRQS; i++) {
spin_lock(&desc->lock); /* irq = A */
if (desc->status & IRQ_INPROGRESS) {
As the second lock on both CPUs is taken before checking that this irq is
being handled in another processor this may cause a deadlock. This issue
is only theoretical.
I propose the attached patch to fix booth problems: when trying to handle
misrouted IRQ active desc->lock may be unlocked.

[PATCH] pci: don't try to remove sysfs files before they are setup.
The PCI sysfs attributes are created after the initial PCI bus scan. With
the addition of more return value checking and assertions in the device and
sysfs layers we now can get dumps like this on sparc64:

[ 20.135514] PCI0(PBMB): Bus running at 33MHz
It's triggering because removal of the "config" PCI sysfs file for the
device fails.
On sparc64, after probing the device, we'll delete the PCI device via
pci_remove_bus_device() if we cannot find the firmware device tree node
corresponding to it.
This is fine, but at this point the sysfs files for the PCI device won't be
setup yet.
So we should not try to do anything in pci_remove_sysfs_dev_files() if
pci_sysfs_init() has not run yet.

The previous fixes for the use after free in xfs_iunpin left a nasty log
deadlock when xfslogd unpinned the inode and dropped the last reference to
the inode. the ->clear_inode() method can issue transactions, and if the
log was full, the transaction could push on the log and get stuck trying
to push the inode it was currently unpinning.
To fix this, we provide xfs_iunpin a guarantee that it will always have a
valid xfs_inode <-> linux inode link or a particular flag will be set on
the inode. We then use log forces during lookup to ensure transactions are
completed before we recycle the inode. This ensures that xfs_iunpin will
never use the linux inode after it is being freed, and any lookup on an
inode on the reclaim list will wait until it is safe to attach a new linux
inode to the xfs inode.

[POWERPC] pseries: Force 4k update_flash block and list sizes
The enablement of 64k pages on pseries platforms exposed a bug in
the RTAS mechanism for updating firmware. RTAS assumes 4k for flash
block and list sizes, and use of any other sizes results in a failure,
even though PAPR does not specify any such requirement.
This patch changes the rtas_flash module to force the use of 4k memory
block and list sizes when preparing and sending a firmware image to
RTAS. The rtas_flash function now uses a slab cache of 4k blocks with
4k alignment, rather than get_zeroed_page(), to allocate the memory for
the flash blocks and lists. The 4k alignment requirement is specified
in PAPR.

[PATCH] sysctl: Undeprecate sys_sysctl
The basic issue is that despite have been deprecated and warned about as a
very bad thing in the man pages since its inception there are a few real
users of sys_sysctl. It was my assumption that because sysctl had been
deprecated for all of 2.6 there would be no user space users by this point,
so I initially gave sys_sysctl a very short deprecation period.
Now that I know there are a few real users the only sane way to proceed
with deprecation is to push the time limit out to a year or two work and
work with distributions that have big testing pools like fedora core to
find these last remaining users.
Which means that the sys_sysctl interface needs to be maintained in the
meantime.
Since I have provided a technical measure that allows us to add new sysctl
entries without reserving more binary numbers I believe that is enough to
fix the sys_sysctl binary interface maintenance problems, because there is
no longer a need to change the binary interface at all.
Since the sys_sysctl implementation needs to stay around for a while and
the worst of the maintenance issues that caused us to occasionally break
the ABI have been addressed I don't see any advantage in continuing with
the removal of sys_sysctl.
So instead of merely increasing the deprecation period this patch removes
the deprecation of sys_sysctl and modifies the kernel to compile the code
in by default.
With committing to maintain sys_sysctl we get all of the advantages of a
fast interface for anything that needs it. Currently sys_sysctl is about
5x faster than /proc/sys, for the same string data.

When ACPI && NUMA, pxm_to_node is used and it exists in drivers/acpi/numa.c
Tony said:
The patch makes sense ... if you pick both of "ACPI" and "NUMA", then you
need (and should automatically be given) ACPI_NUMA too.
The only open question is whether there is a better way of getting there.
Perhaps with less configuration options in the first place? We are heading
towards a future where so many systems will be NUMA that there would seem to
be little benefit in keeping ACPI_NUMA separate from ACPI ... but perhaps
we aren't quite there yet.

[PATCH] md: do not freeze md threads for suspend
If there's a swap file on a software RAID, it should be possible to use this

available to the memory management subsystem when memory is being freed before
the suspend image is created.
For the above reasons it seems that md_threads should not be frozen during the
suspend and the appended patch makes this happen, but then there is the
question if they don't cause any data to be written to disks after the suspend
image has been created, provided that all filesystems are frozen at that time.

[PATCH] md: change ONLINE/OFFLINE events to a single CHANGE event
It turns out that CHANGE is preferred to ONLINE/OFFLINE for various reasons
(not least of which being that udev understands it already).
So remove the recently added KOBJ_OFFLINE (no-one is likely to care anyway)
and change the ONLINE to a CHANGE event

[PATCH] dm: fix find_device race
There is a race between dev_create() and find_device().
If the mdptr has not yet been stored against a device, find_device() needs to
behave as though no device was found. It already returns NULL, but there is a
dm_put() missing: it must drop the reference dm_get_md() took.
The bug was introduced by dm-fix-mapped-device-ref-counting.patch.
It manifests itself if another dm ioctl attempts to reference a newly-created
device while the device creation ioctl is still running. The consequence is
that the device cannot be removed until the machine is rebooted. Certain udev
configurations can lead to this happening.

to nfsd_create_v3. This is ugly. This will be fixed by later patches.

[PATCH] Regression in 2.6.19-rc microcode driver
If the microcode driver is built in (rather than module) there are some,
ehm, interesting effects happening due to the new "call out to userspace"
behavior that is introduced.. and which runs too early. The result is a
boot hang; which is really nasty.
The patch below is a minimally safe patch to fix this regression for 2.6.19
by just not requesting actual microcode updates during early boot. (That
is a good idea in general anyway)
The "real" fix is a lot more complex given the entire cpu hotplug scenario
(during cpu hotplug you normally need to load the microcode as well); but
the interactions for that are just really messy at this point; this fix at
least makes it work and avoids a full detangle of hotplug.

[CIFS] Fix mount failure when domain not specified
Fixes Samba bugzilla #4176
When users do not specify their domain on mount, 2.6.18 started sending
default domain instead of a null domain (which was the only way on some
servers to use a default domain). Users of 2.6.18 who did not specify
their domain name on mounts to certain common Windows servers that were
members of a domain, but not the domain controller, would get mount
failures which they did not get in 2.6.18
This fixes that issue and should remove complaints about mount
behavior changing.

x86-64: write IO APIC irq routing entries in correct order
This is the x86-64 version of f9dadfa71bc594df09044da61d1c72701121d802
that did the same thing on i386.
Since the "mask" bit is in the low word, when we write a new entry, we
need to write the high word first, before we potentially unmask it.
The exception is when we actually want to mask the interrupt, in which
case we want to write the low word first to make sure that the high word
doesn't change while the interrupt routing is still active.

x86-64: clean up io-apic accesses
This is just commit 130fe05dbc0114609cfef9815c0c5580b42decfa ported to
x86-64, for all the same reasons. It cleans up the IO-APIC accesses in
order to then fix the ordering issues.
We move the accessor functions (that were only used by io_apic.c) out of
a header file, and use proper memory-mapped accesses rather than making
up our own "volatile" pointers.

to reserve the MMCONFIG mmio memory ranges, but since the MMCONFIG

most of the time _anyway_), it does more harm than good.
