[PATCH] PPC64 Replace cmp instructions with cmpw/cmpd
There were a few places in assembly code in the ppc64 part of the
kernel where we were using the old forms of the compare instruction
(cmp, cmpi, cmpl, cmpli) which don't specify the operand size (word or
doubleword). These have been accepted for a long time for backward
compatibility with the old POWER architecture (and defaulted to a
32-bit comparison) but are now being rejected by the latest versions
of binutils. Some of them were actual bugs in that they were on
things which were actually 64-bit values such as pointers (not that
any of them actually caused a problem in practice).
This patch replaces cmp{,l}{,i} with cmp{,l}[wd]{,i} as appropriate.
The original patch was from Segher Boessenkool, slightly modified by
me.

Currently hostfs passes the rdev value from stat() on the host as rdev
value to return to stat() on the guest; but we cannot pass rdev as is
because glibc and the kernel disagree about its definition. So we must
decode it in a major/minor couple with glibc macros and re-encode it in
kernelspace code.

setting drop_inode = generic_delete_inode).

[PATCH] Use cache_decay_ticks instead of a constant
This patch, based on Ken Chen's patch, changes the default 2.5 msec
migration-cutoff value to be based on cache_decay_ticks, which is what
we used for a long time prior the sched-domains code. (If an
architecture does not set cache_decay_ticks then 2.5 msec is used.)
This causes the following new migration-cutoff values on various SMP
systems:
[*] ppc64 does not set cache_decay_ticks so we fall back to the
default.
I believe in light of previous testing we could attempt this for 2.6.9 as
well. (Note: that the 2.6.9-rc3 patch looks similar but needs to patch
kernel/sched.c. Note2: this patch is different from Ken's original one.)

x86-64 in_gate_vma would take a read lock on the VMA when the passed

This would be called by get_user_pages, which already holds the mmap_sem.
Unfortunately some callers of get_user_pages hold the mmap_sem for writing,
which could in theory cause a deadlock.
I think it can currently not happen because the only users who hold it for
write before calling gup() are coredump and AIO in the ring setup, and both
should not ever access the vsyscall page.
But not taking the semaphore is safer and avoid this here.
