e2fd58d06f [SPARC64]: VIO device addition log message level is too high.
There is no reason this should be KERN_ERR, KERN_INFO is

4007b493ee libata: fix for sata_mv >64KB DMA segments
Fix bug in sata_mv for cases where the IOMMU layer has merged SG entries
to larger than 64KB. They need to be split up before being sent to
the driver.

Just for simplicity's sake, split up at 64K boundary instead of 64K size,
since that's what the common code does anyway.

25e5566ed3 [SPARC64]: Fix missing load-twin usage in Niagara-1 memcpy.
For the case where the source is not aligned modulo 8
we don't use load-twins to suck the data in and this
kills performance since normal loads allocate in the
L1 cache (unlike load-twin) and thus big memcpys swipe
the entire L1 D-cache.

We need to allocate a register window to implement this
properly, but that actually simplifies a lot of things
as a nice side-effect.

9b42c336d0 [TCP]: secure_tcp_sequence_number() should not use a too fast clock
TCP V4 sequence numbers are 32bits, and RFC 793 assumed a 250 KHz clock.
In order to follow network speed increase, we can use a faster clock, but
we should limit this clock so that the delay between two rollovers is
greater than MSL (TCP Maximum Segment Lifetime : 2 minutes)

Choosing a 64 nsec clock should be OK, since the rollovers occur every
274 seconds.

cf8dc57cba x86_64: increase VDSO_TEXT_OFFSET for ancient binutils
For some reason old binutils genertate larger headers so increase the text
offset of the vdso to avoid linker errors.

Roland McGrath explains:
  "There are extra symbols in the '.dynsym' section that are responsible
   for the size difference (They also cause corresponding inflation in
   '.gnu.version')

   Older ld's wrongly generated these unneeded symbols in .dynsym.  This
   was fixed not all that long ago (2006); binutils-2.17.50.0.6 might be
   the first fixed version, but I have not verified for sure where the
   cutoff was.

   The unneeded symbols et al from old ld add almost 700 bytes excess.
   This limits fairly tightly the amount by which the actual text and
   data in the vDSO can grow in the future without pushing the whole
   file over 4kb.  If it does grow later on, we should consider changing
   the layout with a config option or something to pack it better
   without that padding, when building the kernel with newer binutils."

e48395f175 [POWERPC] Fix xics set_affinity code
On a POWER6 machine running 2.6.23-rc8 I sometimes see the following error:

xics_set_affinity: No online cpus in the mask 00000000,00000000,00000000,00000001 for irq 20

In a desperate attempt to get a changelog entry in 2.6.23, I took a look
into it.

It turns out we are passing a real and not a virtual irq into
get_irq_server.  This works for the case where hwirq < NR_IRQS and we
set virq = hwirq.  In my case however hwirq = 590082 and we try and
access irq_desc[590082], slightly past the end at 512 entries.

Lucky we ship lots of memory with our machines.

564256c9e0 Revert "[XFS] Avoid replaying inode buffer initialisation log items if on-disk version is newer."
This reverts commit b394e43e99.

Lachlan McIlroy says:
    It tried to fix an issue where log replay is replaying an inode cluster
    initialisation transaction that should not be replayed because the inode
    cluster on disk is more up to date.  Since we don't log file sizes (we
    rely on inode flushing to get them to disk) then we can't just replay
    all the transations in the log and expect the inode to be completely
    restored.  We lose file size updates.  Unfortunately this fix is causing
    more (serious) problems than it is fixing.

9f96cb1e8b robust futex thread exit race
Calling handle_futex_death in exit_robust_list for the different robust
mutexes of a thread basically frees the mutex.  Another thread might grab
the lock immediately which updates the next pointer of the mutex.
fetch_robust_entry over the next pointer might therefore branch into the
robust mutex list of a different thread.  This can cause two problems: 1)
some mutexes held by the dead thread are not getting freed and 2) some
mutexs held by a different thread are freed.

8792f961ba VT ioctl race fix
