It seems 8139cp.c has the race condition of rx_poll and interrupt.
NOTE, since I don't have this device, patch is untested. Sorry.
I got a Wacom Graphire3 for my birthday and unfortunately it didn't
work. After some playing around, I noticed the 2.6 kernel needs a few
small modifications to make it work.
This simple patch adds support for the Wacom Graphire 3.

[PATCH] Fix for aacraid and high memory on 2.6.1
Here is an update to use pci_set_consistent_dma_mask. But since
dma_alloc_coherent uses dma_mask instead of consistent one, I left in
setting dma_mask as well until the alloc routine changes.

[PATCH] x86-64 merge
Mainly lots of bug fixes and a few minor features. One change is that
it uses drivers/Kconfig now like i386. This requires a few minor changes in
outside Kconfig files which I am sending separately.
- Tighten/fix some code in NUMA node discovery
- Fix oopses in threaded 32bit coredumps and read correct registers.
- Merge with 2.6.2rc1
- Sync arch/x86_64/Kconfig with i386. Uses drivers/Kconfig now.
- Remove bcopy export
- Fix check for signal stack for 32bit signals
- Fix bcopy and exit prototypes for gcc 3.4
- Fix asm contraint in usercopy.c for gcc 3.4
- Use rt_sigreturn, not sigreturn for rt sigreturns.
- Pass si_fault address to 32bit
- Truncate si_error to 16bit in 32bit emulation to match i386
- Move IA32 flag switching for 32bit executables to flush_thread
(code copied from ppc64/sparc64)
- Print exception trace for strace too, share code.
- Default to 3GB address space for a.out executables
- Fix security hole in ptrace. Also fixes some problems with 32bit gdb.
- Sync mmap address selection algorithm with mm/mmap.c version
- Disable a.out coredumps completely
- Fix bug in sigaltstack 32bit emulation. Kylix IDE now works.
- Move errata 93/BIOS workaround into fault handler. This should work
around USB legacy BIOS bugs too, although not completely (we cannot fix
faults injected by SMM into user space 64bit processes)
- Quieten some unimplemented 32bit syscall warnings and avoid repeated
warnings.
- Set LDT segment limit correctly (fixes problems with some modify_ldt
user)
- Remove obsolete ldt rw lock.
- Remove sys32_modify_ldt. The standard sys_modify_ldt is equivalent.
- Remove traces of old kgdb support
- Merge CFI changes from Jim Houston and some other smaller changes The
kernel assembly functions are described with dwarf2 unwind
information now, which makes it easier for debuggers to make sense of
stack backtraces. The code is only enabled with CONFIG_DEBUG_INFO.
Note this implies that when you use CONFIG_DEBUG_INFO you may need
an binutils update.
- defconfig updated
- Readd sleep support code (Pavel Machek)
- Drop fusion and flush workarounds from IOMMU code
- Add iommu=nofullflush option
- Rewrite 32bit emulation for siginfo conversion (Joe Korty)
- Allow remapping of scatterlists after unmap. This fixes some problems
with the SCSI layer retrying previously mapped sg lists when iommu
merging was enabled (it's disabled now by default)
- Port HPET rtc device emulation code from i386

[MULTICAST]: multicast loop with include filters fix
When sending a multicast and using looping back a copy to the
local machine, the interface filter checks can be done before the
source address is specified. For an INCLUDE filter, this won't match
the allowed sources and the packets won't be delivered locally,
even when the ultimate source address chosen is in the allowed list.
The patch below fixes the filter checks for both IGMPv3 and MLDv2
to only apply when a source address is available.
Thanks to Steven Hessing for reporting the problem and providing
a test case for reproducing it.

[PATCH] ppc32: Fixes to the signal context code
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
This patch (which has been in my tree for some time now) does 2 things to
the ppc32 signal code:
- The new sys_swapcontext() syscall that we added recently (and which is
_not_ yet used by glibc, so it's ok to change it slightly at this point,
glibc kernel version check will limit us to 2.6.2 or 2.6.3) gets a new
context size argument, so we can deal with future context size changes.
- When ucontext is get/set/swapped using the above syscall, the TLS (r2)
is preserved (it's still saved/restored on signal entry & return though).
The equivalent of this patch is already in the ppc64 signal32.c emulation,
and it has no effect until glibc is updated to use the new syscall, which
should happen soon now, so please apply.
[PATCH] non-integrated local APIC LVTT init compatibility
Add back the old i82489DX bits to use timer scaling for the old

but not having this HW for testing I elected to maintain
the old behaviour on these old machines.

[PATCH] RAID-6 fixes
From: "H. Peter Anvin" <hpa@zytor.com>
As expected, when it hit mainline I started getting real bug reports...
the attached patch does the following:
- Fixes a few x86-64 specific bugs;
- Removes MMX and SSE-1 from x86-64 (if we have x86-64 we have SSE-2);
- Slightly astracts the integer code to make it easier to add
architecture-specific optimizations later (e.g. IA64 once gcc gets
better IA64 intrinsics support);
- Resurrects the user-space testbench, and makes it not output the known
false positive of the D+Q case (D+Q is equivalent to a RAID-5 recovery,
so I didn't implement it in the user-space testbench.)

[IPV6]: Add and use new 'strict' parameter to ip6_chk_addr().
RFC 2461 requires that the source address of Neighbor Discovery messages
is an address assigned to the sending interface.
Duplicate Address Detection should also be interface specific. We don't,
for example, want a node to DoS itself just because it has two interfaces
on the same link and both happen to listen to the same multicast group. If
there is a true duplicate on the link, the interface doing DAD will notice
it anyway.
The attached patch adds a 'strict' parameter to ip6_chk_addr() and
ip6_get_ifaddr() to allow link-local protocols like ND and DAD to do
strict address checks even on addresses with greater scope than
link-local.
