[XFS] A problem was found with the debug code in xlog_state_do_callback. At
the end of processing all log buffers that can be processed, there is
a (debug only) double-check to make sure that log buffers with
completed I/O don't get marooned when the function completes. The
check only needs to go to the first buffer that will cause an I/O
completion, that has not completed. The loop doesn't stop a WANT_SYNC
state buffer is found, but it should.

[PATCH] fix oops caused when writing to the rescan attribute
If an upper layer driver is not loaded, and you write to a device's
rescan attribute you will get an oops. The attached patch fixes this by
testing if the device's driver variable is set before accessing it.
<dougg-AT-torque.net>
[PATCH] SCSI constants.c
However, drivers/scsi/constants.c does know about Report Luns??
Looks like a merging problem by Andries and me sometime back.
<patmans-AT-us.ibm.com>
[PATCH] SCSI: limit mode sense usage
Re-roll of the patch against 2.6.0-test6 to allow overriding or setting of
mode sense related flags, includes Alan Stern's as95 patch minus his
scsiglue.c changes.
Moves scsi_devinfo.h for use outside of drivers/scsi, and adds three new
devinfo flags:
BLIST_MS_SKIP_PAGE_08
BLIST_MS_SKIP_PAGE_3F
BLIST_USE_10_BYTE_MS
Adds a per host template flags, and use of it in scsiglue.c. The per host
value can be overridden by a devinfo entry, the patch does not allow
scsi_default_dev_flags to override default host values.
USB mass storage and removable media (for testing mode page 3f use) were
not tested, if you have a USB storage device that still chokes on mode
sense 3f please give this a spin.

[PATCH] ia64: fix EFI memory map trimming
This fixes a problem in EFI memory map trimming. For example,
here's part of the memory map on my i2000:
mem00: type=4, attr=0x9, range=[0x0000000000000000-0x0000000000001000) (0MB)
mem01: type=7, attr=0x9, range=[0x0000000000001000-0x0000000000088000) (0MB)
mem02: type=4, attr=0x9, range=[0x0000000000088000-0x00000000000a0000) (0MB)
mem03: type=5, attr=0x8000000000000009, range=[0x00000000000c0000-0x0000000000100000) (0MB)
mem04: type=7, attr=0x9, range=[0x0000000000100000-0x0000000004000000) (63MB)
mem05: type=2, attr=0x9, range=[0x0000000004000000-0x00000000049ba000) (9MB)
mem06: type=7, attr=0x9, range=[0x00000000049ba000-0x000000007ec0b000) (1954MB)
...
There's a hole at 0xa0000-0xc0000, so we should ignore all the WB memory
in that granule. With 16MB granules, the existing code trims like this
(note the 4K page at 0x0 should have been ignored, but wasn't).
<jbarnes-AT-sgi.com>
[PATCH] ia64: zero out topology related sysfs nodes
Tony pointed out (thanks Tony) that in -test8 kobject_set_name() will
try to free a kobject's k_name field if it's non-NULL, so we need to
zero it out in case kmalloc() gave us recycled memory or we'll try to
kfree a bogus area.
<davidm-AT-tiger.hpl.hp.com>
ia64: Sync with i386 irq.c (deadlock avoidance for certain disable_irq()/
enable_irq() sequences).
<arun.sharma-AT-intel.com>
[PATCH] ia64: make strace of ia32 processes work again
Newer versions of strace manipulate the syscall arguments and to make this
work for ia32 processes, we need to reload the syscall args after
doing the syscall-trace callback.
<eranian-AT-hpl.hp.co>
[PATCH] ia64: two perfmon fixes
- converts hdr_cur_pos into hdr_cur_offs to avoid leaking kernel
addresses to userland. As a consequence hdr_last_pos is gone.
- correct buffer saturation mode bug by which the hdr_count would
be reset, leading to no visible samples collected.
<B.Zolnierkiewicz-AT-elka.pw.edu.pl>
[PATCH] fix drivers/ide/pci/siimage.c for PROC_FS=n
From: "Noah J. Misch" <noah-AT-caltech.edu>
The Silicon Image driver is not building properly when CONFIG_PROC_FS is unset.
This patch corrects that problem. It appears as though several utility
functions at the top of drivers/ide/pci/siimage.c that the driver always needs
accidentally fell within an #ifdef CONFIG_PROC_FS. I also removed an excess
include while I noticed it.
<kraxel-AT-bytesex.org>
[PATCH] Fix bttv BUG() at video-buf.c:378
As found by Herbert Xu: the last v4l update broke bttv. videobuf_iolock
was passed a vb that has just been filled with zeros.
Fixed like this.
<neilb-AT-cse.unsw.edu.au>
[PATCH] md - Use sector rather than block numbers when splitting raid0 requests.
When raid0 needs to split a request, it uses 'block' (1K) addresses
rather than sector (512b) addresses, which causes problems if the sector
address is odd. This patch fixes the problem.
Thanks to Andy Polyakov <appro-AT-fy.chalmers.se>
<neilb-AT-cse.unsw.edu.au>
[PATCH] kNFSd - In READDIRPLUS reply, don't return a file handle for a mounted directory.
... as if "nohide" is in used, it will be the wrong filehandle, and
returning a filehandle is optional anyway.

<viro-AT-parcelfarce.linux.theplanet.co.uk>
[PATCH] Fix initrd with devfs enabled
This fixes initrd with devfs. With that combination the late-boot code
does temporary mount of devfs over rootfs /dev, which made /dev/initrd
inaccessible. For setups without devfs that didn't happen.
The fix is trivial - put the file in question outside of /dev; IOW,
we simply replace "/dev/initrd" with "/initrd.image" in init/*.

[LLC]: Make LLC2 compile with PROC_FS=n
<da-x-AT-gmx.net>
[NET]: Fix sysctl breakage during network device renaming.
Sysctl assumes its ctl_table.procname field is const, but the
networking points ctl_table.procname to dev->name. When renaming
a network device using SIOCSIFNAME, dev->name is modified and
sysctl's assumption breaks, causing this behaviour, at least:
1. sysctl wouldn't be able to remove the proc entry when the
device requests to be unregistered, because it would be
using the new name instead of the old one.
2. proc entries for devices remain with the old name after
rename.
This change includes allocating the current device name to a
new copy upon registering with sysctl, plus re-registering with
sysctl when the device is renamed.
This only fixes IPv4, IPv6, and net/core/neightbour.c.
Fixes for ax25 and decnet are also planned.

[PATCH] Fix bugs in various DVB drivers
- DVB networking uses big endian crc32, so change all occurences of
crc32_le to crc32_be
- fix usage of firmware location Kconfig option in tda1004x frontend
driver
- add missing VBI line decoding initialization to saa7113 code for
av7110 driver
- make av7110 firmware static and *not* __initdata, so recover_arm()
can work in case the driver is compiled in statically
<hunold-AT-linuxtv.org>
[PATCH] Fix bug in saa7146 analog tv i2c-handling
- remove cruft, add I2C_ADAP_CLASS_TV_ANALOG identifier for analog tv
i2c handler
<hunold-AT-linuxtv.org>
[PATCH] Fix bugs in analog tv i2c-helper chipset drivers
- remove cruft, memset() i2c-client structures in tda9840, tea6420,
tea6415c driver, otherwise i2c_register()/kobject() segfaults later on
<B.Zolnierkiewicz-AT-elka.pw.edu.pl>
[PATCH] fix drivers/ide/pci/cmd640.c for CONFIG_PCI=n
CMD640 driver also supports VLB version of the chipset, therefore fix
drivers/ide/Makefile to include pci/ subdir even if CONFIG_BLK_DEV_IDEPCI=n.

[ARM PATCH] 1691/1: Fix IOP321 platform booting in 2.6
Patch from Dave Jiang
The fix allows IOP321 based platforms to boot all the way instead of
blank screen after "starting kernel...". Inherited from Deepak's
earlier patch.

[libata] Integrate Serial ATA driver into kernel tree.
<davidm-AT-tiger.hpl.hp.com>
ia64: Fix efi_mem_type() and efi_mem_attributes() to avoid potential
underflows. In my case, the underflows occurred with the
first memory descriptor which got trimmed down to a size of 0.
Due to the underflow, this descriptor ended up covering the entire
address-range which in turn caused Bad Things to happen with the
X server.
<davidm-AT-tiger.hpl.hp.com>
ia64: Patch by Arun Sharma: fix allocation/handling of GDT shared page (the old code
was inconsistent and in places still assumed there is both a GDT and a TSS
shared page, but the latter was removed a long time ago).
<jamesclv-AT-us.ibm.com>
[PATCH] Allow more APIC irq sources
The "irq_vector[]" array is indexed by the sum of all RTEs in all I/O
APICs, and is not necessarily limited by the x86 CPU irq vector inputs.
In fact, the irq vector index would overflow on big machines with lots
of IO APIC's, causing the boot to fail.
So grow the array for the big SMP boxes, keeping the default the same as
before (and shrink the vector entry size down to a 8-bit value, since
that's the size of the actual CPU vector entry).

[IPV6]: Set fl->proto in _decode_sesseion6.
<davem-AT-nuts.ninka.net>
[TG3]: Disable/enable timer in suspend/resume.
<davem-AT-nuts.ninka.net>
[NET COMPAT]: Fix hangs caused by bugs in do_netfilter_replace().
It is illegal to try to access things via userspace pointers
after set_fs(KERNEL_DS), and that is exactly what this function
was doing. Fix by using compat_alloc_user_user_space(), this
preserves the copy minimization the original code had.

[PATCH] fix split_vma vs. invalidate_mmap_range_list race
From: "V. Rajesh" <vrajesh-AT-eecs.umich.edu>
If a vma is already present in an i_mmap list of a mapping,
then it is racy to update the vm_start, vm_end, and vm_pgoff
members of the vma without holding the mapping's i_shared_sem.
This is because the updates can race with invalidate_mmap_range_list.
I audited all the places that assign vm_start, vm_end, and vm_pgoff.
AFAIK, the following is the list of questionable places:
1) This patch fixes the racy split_vma. Kernel 2.4 does the
right thing, but the following changesets introduced a race.
http://linux.bkbits.net:8080/linux-2.5/patch-AT-1.536.34.4
http://linux.bkbits.net:8080/linux-2.5/patch-AT-1.536.34.5
You can use the patch and programs in the following URL to
trigger the race.
http://www-personal.engin.umich.edu/~vrajesh/linux/truncate-race/
2) This patch also locks a small racy window in vma_merge.
3) In few cases vma_merge and do_mremap expand a vma by adding
extra length to vm_end without holding i_shared_sem. I think
that's fine.
4) In arch/sparc64, vm_end is updated without holding i_shared_sem.
Check make_hugetlb_page_present. I hope that is fine, but
I am not sure.
<akpm-AT-osdl.org>
[PATCH] scsi: handle zero-length requests
From: Jens Axboe <axboe-AT-suse.de>
The command 'eject /dev/scd0' sends a START_STOP command to the device with
the data direction set to SCSI_DATA_WRITE but a transfer length of zero.
This causes a problem for some code paths.
<akpm-AT-osdl.org>
[PATCH] ia32 limit_regions update

ChangeSet-AT-1.404.2.2 2002-05-06 21:30:10-03:00 hch-AT-infradead.org
[PATCH] memsetup fixes (again)
The mem= fixes from Red Hat's tree had a small bug:
if mem= was not actually used with the additional features, but
int plain old way, is used the value as the size of memory it
wants, not the upper limit. The problem with this is that there
is a small difference due to memory holes.
I had one report of a person using mem= to reduce memory size for
a broken i386 chipset thaty only supports 64MB cached and the rest
as mtd/slram device for swap. I got broken as the boundaries changed.
<akpm-AT-osdl.org>
[PATCH] Fix unmap_vmas() compile warning
Silence a bogus "may be used uninitialised" warning. It only affects
architectures which use the tlb_finish_mmu() args.
<akpm-AT-osdl.org>
[PATCH] Time precision, adjtime(x) vs. gettimeofday
From: Stephen Hemminger <shemminger-AT-osdl.org>
The following will prevent adjtime from causing time regression. It delays
starting the adjtime mechanism for one tick, and keeps gettimeofday inside
the window.
Only fixes i386, but changes to other arch would be similar.
Running a simple clock test program and playing with adjtime demonstrates
that this fixes the problem (and 2.6.0-test6 is broken). But given the
fragile nature of the timer code, it should go through some more testing
before inclusion.
<akpm-AT-osdl.org>
[PATCH] atp870u oops fix
This driver is taking uinitialised stack gunk from the pdev[] array and
feeding it into pci_read_config_byte() and crashing when modprobed with no
hardware present.
Fix it to not index past the initialised members of pdev[].
We don't know if this driver works.

[PATCH] tmpfs 1/7 LTP ENAMETOOLONG fix
From: Hugh Dickins <hugh-AT-veritas.com>
LTP tests the filesystem on /tmp: there are many failures when using tmpfs
because simple_lookup forgot to reject filenames longer than the NAME_MAX
tmpfs declares in its statfs. This also fixes ramfs and hugetlbfs.
<akpm-AT-osdl.org>
[PATCH] tmpfs 2/7 LTP S_ISGID on directories fix
From: Hugh Dickins <hugh-AT-veritas.com>
LTP tests the filesystem on /tmp: many failures when tmpfs because it missed
the way directories hand down their gid. Also fix ramfs and hugetlbfs.
<akpm-AT-osdl.org>
[PATCH] tmpfs 3/7 swapoff/truncate race fix
From: Hugh Dickins <hugh-AT-veritas.com>
On 23 July, Sergey S. Kostyliov <rathamahata-AT-php4.ru> reported a tmpfs
BUG_ON(inode->i_blocks) during swapoff: my last version of the fix to
swapoff/truncate race was inadequate, since I_FREEING might get set or
i_size be reduced (from another cpu) the instant after it's tested here.
So revert to the previous version of the fix, shmem_truncate calling
truncate_inode_pages again, if pages still left in cache; but avoid the
recall in usual cases of partial truncation, by having a "pagein" flag
to indicate when recall might be necessary. (Since those flags already
use VM_ACCOUNT and VM_LOCKED, must redefine another VM_flag for this.)
Sergey and 2.4-aa have run fine with this for a couple of months.
<akpm-AT-osdl.org>
[PATCH] tmpfs 4/7 getpage/truncate race fix
From: Hugh Dickins <hugh-AT-veritas.com>
Extend use of that SHMEM_PAGEIN flag to where shmem_getpage adds a page
to the cache. It couldn't have caused a BUG_ON(inode->i_blocks), but if
i_size is reduced (from another cpu) the instant after shmem_swp_alloc
checks it, shmem_getpage could insert a page into the cache just after
truncate_inode_pages has passed through cleaning it, leaving stale data
(which may mysteriously reappear if the file is later extended).
Easily fixed for tmpfs, using the mechanism just added for swapoff; and
probably more important there, since its read from swap can insert non-0
data. But is there not a similar issue, a tiny window, in filemap.c?
if truncate_inode_pages comes in between checking i_size and adding new
page to cache. Not worth getting excited, but something to beware of.
<akpm-AT-osdl.org>
[PATCH] tmpfs 5/7 writepage/truncate race fix
From: Hugh Dickins <hugh-AT-veritas.com>
If it's possible for a tmpfs page beyond i_size to remain in cache until
shmem_truncate repeats truncate_inode_pages, then shmem_writepage's
BUG_ON(index >= info->next_index) cannot be completely safe. But it's a
useful check in a fragile area, so retain it when not in shmem_truncate.
<akpm-AT-osdl.org>
[PATCH] tmpfs 6/7 write i_size_write
From: Hugh Dickins <hugh-AT-veritas.com>
mm/shmem.c was converted to i_size_read in -test1, and the remaining
references to a file's naked i_size are safely protected by i_sem;
but surely shmem_file_write must use i_size_write to update i_size.
<akpm-AT-osdl.org>
[PATCH] tmpfs 7/7 write mark_page_accessed
From: Hugh Dickins <hugh-AT-veritas.com>
mm/filemap.c's generic_file_aio_write_nolock changed SetPageReferenced
to mark_page_accessed in -test3: now follow that in shmem_file_write.

From: "Kurtis D. Rader" <kdrader-AT-us.ibm.com>
http://bugme.osdl.org/show_bug.cgi?id=1365
The digi_acceleport.c USB serial driver has a bogus "address of" operator
that results in BUGs.
The problem is that digi_wakeup_write_lock() takes a pointer to a struct
usb_serial_port. However, what gets passed is a pointer to a pointer to a
struct usb_serial_port.

[PATCH] fs/binfmt_elf.c:load_elf_binary() doesn't verify interpreter arch
From: Peter Bergner <bergner-AT-vnet.ibm.com>
In fs/binfmt_elf.c:load_elf_binary() (both 2.6 and 2.4), there is some
minimal checking whether the interpreter it's about to load/run is a valid
ELF file, but it fails to check whether the interpreter is of the correct
arch. We ran into this when a borked powerpc64-linux toolchain set the
interpreter on our 64-bit app to our 32-bit ld.so. Executing the app
caused the kernel to really chew up memory. I'm assuming x86_64 and
sparc64 might possibly see the same behavior.
Note I'm not sure of the history behind INTERPRETER_AOUT, so I added the
test for INTERPRETER_ELF so as not to change it's behavior in case someone
still relies on it.
As an aside, it seems the elf_check_arch() macros should really be checking
for more than a valid e_machine value. I'd think checking one or more of
the e_ident[EI_CLASS], e_ident[EI_DATA] and e_ident[EI_OSABI] values would
be required as well, no?

[PATCH] fix low-memory BUG in slab
cache_grow() will call kmem_freepages() if the call to alloc_slabmgmt()
fails. But the pages have not been marked PageSlab at this stage, so
kmem_freepages() goes BUG.
It is more symmetrical to mark the pages as PageSlab in kmem_getpages().
The patch also prunes a bunch of incorrect comments.
(PageSlab doesn't actually do anything: its only value is as a debug check.
I think the LKCD patch uses it).

[PATCH] fix for register_cpu()
From: jbarnes-AT-sgi.com (Jesse Barnes)
The patch adds a symlink from /sys/devices/system/node/nodeM/cpuN to the
/sys/devices/cpu/cpuN directory so that a userspace program can determine

NULL in for the root arg and everything will work like it used to.

[PATCH] make printk more robust with "null" pointers
Expand printk's traditional handling of null pointers so that anything in the
first page is considered a null pointer.
This gives us better behaviour when someone (acpi..) accidentally prints a
string which is embedded in a struct, the pointer to which is null.

[PATCH] kcapi.c CONFIG_MODULES=n build fix
With CONFIG_MODULES=n this file does not compile because the type of

card->owner at all.

[PATCH] Fix oops with CONFIG_MCA=y
With CONFIG_MCA=y and no MCA bus present, drivers go oops deep in the kobject

[PATCH] v850: Workaround for tty-driver init-order problem
From: miles-AT-lsi.nec.co.jp (Miles Bader)
Use `late_initcall' instead of just `__initcall' as a workaround for
the fact that (1) simcons_tty_init can't be called before tty_init,
(2) tty_init is called via `module_init', (3) if statically linked,
module_init == device_init, and (4) there's no ordering of init lists.
We can do this easily because simcons is always statically linked, but
other tty drivers that depend on tty_init and which must use
`module_init' to declare their init routines are likely to be broken.

[PATCH] Add needed __devexit_p's to two gameport drivers
From: "Noah J. Misch" <noah-AT-caltech.edu>
Two gameport drivers need __devexit_p wrapped around their remove

that.
Wrapped a __devexit_p around the 'remove' functions of two gameport
drivers. The lack of __devexit_p was wrong according to linux/init.h,
differed from the practices in nearby files, and caused a link error with
binutils 2.14.90.0.5.

[PATCH] early_serial_setup array bounds check
From: Bjorn Helgaas <bjorn.helgaas-AT-hp.com>
early_serial_setup() doesn't validate the array index, so a caller could

that's too large.
I haven't seen a failure related to this, but it seems fragile to rely on
callers to know how many ports the driver supports.

your initdata (more error checking should probably be added). The
second fixes a memcpy to a physical address.

[PATCH] Add release function to sd for scsi_disk structure
This patch removes the delay in calling device_del on the sdev struct
device during a surprise removal event. Reference counting functions for
sd's scsi_disk structure where also added to fix issues of unregistering
when a sd is open.
I have tested this patch using scsi_debug with differnt combinations of
adds / removes. I mounted both partitioned and un-partitioned sd disks,
remove the host, and then did a umount. The ref count debug output shows
the objects staying in place prior to the umount and cleaning up once
the umount is called.
This patch fixes an issue with a delayed call of device_del on the
sdev_gendev struct device.
- Remove the delayed call to device_del.
- Add kobject to sd scsi_disk structure.
- Add release function for scsi_disk kobject.
- Add get / put functions for scsi_disk and calls to these
functions.

[XFS] Use an xfs_ino_t to hold the result of inode extraction from a handle, not a possibly 32-bit number
SGI Modid: 2.5.x-xfs:slinx:159943a
<overby-AT-sgi.com>
[XFS] xfs_dir2_node_addname_int had reminants of an old block placement
algorithm in it. The old algorithm appeared to look for the first
place to put a new data block, and thus a new freespace block (this is
where the 'foundindex' variable came from). However, new space in a
directory is always added at the lowest file offset as determined by
the extent list. So this stuff is never used.
I completely ripped out the reminants of the old algorithm, and
(again) moved the freespace block add code inside the conditional
where a data block is added.

<stern-AT-rowland.harvard.edu>
[PATCH] USB: fix for earlier unusual_devs.h patch
An earlier patch caused trouble because it effectively removed the
US_FL_FIX_INQUIRY flag for devices with release number higher than
0x5009. This one might cause problems because it explicitly goes
against the immediately preceding comment in unusual_devs.h. That
comment says that these Casio digital cameras claim to use the CBI
transport when in fact they only use CB. However, there have been two
reports in the last few weeks from people getting the "unneeded SubClass
and Protocol" log messages. One of them was using a device with release
number 0x1000, right at the start of the range. The other had a device
with release number 0x5010, just beyond the end of the current range.
Maybe Casio is marketing two different devices with different behaviors
but having the same Vendor, Product, and Release values -- I don't know.

[PATCH] USB: fix usb-storage self-deadlock
This fixes a problem that showed in usb-storage (osdl bugme 1310)
and could have shown in other drivers that used usb_reset_device()
when they already held dev->serialize: a self-deadlock with some
devices.
There are some drivers that should likely change so that they grab
this lock themselves, since they don't call this during probe()
when the lock is already held. The lock protects against config
changes by other tasks, which is currently quite rate.

[PATCH] ia64: fix broken __emul_prefix
his seems to be broken for ia32 on ia64 and possibly other emulation

path_walk() relative to "/" (which is the case for 2.4).

[PATCH] ia64: fix critical perfmon2 bugs
This patch fixes the following issues:
- fix a nasty corner case by which a task could inherit psr.pp/psr.up
that could be stale by the time it runs. psr.pp/psr.up bits must be
cleared on fork and inherited on execve(). Test case provided by
John Levon.
- mask interrupts when locking the pfm stat structure. We don't want
to take PMU interrupts in the middle of this kind of critical
section.
- fix a bug in pfm_close() for context which use asynchronous
notifications. You cannot call fasync_helper() with interrupts
disabled because it reenables them. There was no real danger of
moving the call outside our critical section.
- fix a bug in in pfm_flush_pmds() where you can leave the freeze bit
set in the pmc saved state.
- updated dump_pmu_state()
- cleanup the BUG_ON() usage

[PATCH] USB: usb enumeration clears full speed ep0 state
This resolves a bug that was recently reported to me by someone
enumerating a USB 1.1 modem through a high speed hub. I'm a bit
surprised we never saw it before; I think cache/dma timings must
usually be strongly in our favor.
The problem was that the HC was still using the old ep0 maxpacket
value, so when it received an 18 byte device descriptor it would
report a packet overrun and enumeration would fail. The fix is
straightforward: invalidate the HC's old endpoint state when we
change the full speed maxpacket size. (And eventually, we can
remove EHCI and OHCI code coping with usbcore not doing this.)

Add a quirk for the Intel ICH-[45] to add special ACPI regions.

up with a normal PCI probe (we do similar quirks for most other
chipsets). Without it, the kernel doesn't know about some magic
IO decodes for the chips.

[PATCH] input / keyboard / Scancode Set 3 support broken
If somebody uses keyboard scancode set 3 it is necessary to explicitly
program the keyboard to send make/break codes for all keys and to set
autorepeat for all keys.
This is critical for some people. One example is the LK461/46W series
of keyboards from Digital Equipment Corporations. These are VMS
keyboards that are also usable on a normal PC.
These keyboards support Scancode Set 2, but for some keys this support
is screwed up -- some function keys (e.g. F18/F20) report the same
scancode sequence combined with both alt and shift keys.
Scancode Set 3 works perfectly if all keys are programmed to give
make/break codes.
A lot of keyboards manufactured by Cherry only make/break for some (not all!)
modifyer keys in scancode set 3 without this fix.
<Knut_Petersen-AT-t-online.de>
[PATCH] setkeycode ioctl fix
This is a bugfix for setkeycode() in /drivers/char/keyboard.c.
If we change a keycode the corresponding bit should be cleared if and
only if this keycode is not defined any longer. I believe that this
also was intended with the original code, but the implementation is
faulty.
First off all the first three changed lines are obviously erroneus:
oldkey == truekey is false or true, you do not need to inclose this in a
for(). I believe the author intended INPUT_KEYCODE(dev,i) == oldkey.
But fixing this alone is not enough.
If somebody wants to interchange the definition of two keys A and B, the
normal way is to use two setkeycode calls:
setkeycode (scancode A, keycode B);
setkeycode (scancode B, keycode A);
The old code does a clearbit(oldkey ..) call even in situations where
two keys have the same definition, and this situation arises commonly in
the situation mentioned above.
Both errors are fixed with this patch.
