[PATCH] exportfs - Remove unnecessary locking from find_exported_dentry()
From: "Jose R. Santos" <jrsantos@austin.ibm.com>
After discussing it with Neil, he fell that the original justification for
taking the kernel_lock on find_exported_dentry() is not longer valid and
should be safe to remove.
This patch fixes an issue while running SpecSFS where under memory
pressure, shrinking dcache cause find_exported_dentry() to allocate
disconnected dentries that later needed to be properly connected. The
connecting part of the code was done with BKL taken which cause a sharp
drop in performance during iterations and profiles showing 75% time spent
on find_exported_dentry(). After applying the patch, time spent on the
function is reduce to <1%.
I have tested this on an 8-way machine with 56 filesystems for several days
now with no problems using ext2, ext3, xfs and jfs.

[PATCH] ppc32: Fix booting some IBM PRePs
From: Tom Rini <trini@kernel.crashing.org>
The following patch comes from Paul Mackerras. Earlier on in 2.6,
arch/ppc/boot/utils/mkprep.c was changed slightly so that it would build
and work on Solaris. Doing this required changing from filling out
pointers to an area to filling out a local copy of the struct. However, a
memcpy was left out, and the info is only needed on some machines to boot.
The following adds in the missing memcpy and allows for IBM PRePs to boot
from a raw floppy again.

[PATCH] x86 vsyscall alignment fix
From: Andy Whitcroft <andyw@uk.ibm.com>
The vsyscall implementation for ia32 provides two different vsyscall pages;
one to use int80 and the other to use sysenter. Each includes a common
signal trailer. The kernel requires the alignment of routines in this
trailer be consistent in both copies. However this is not enforced at
compile time. Failure to maintain this alignment typically leads to an
obscure SIGSEGV in init during boot. This critical alignment requirement
is not well documented.
Below is a patch to better document the alignment requirements and to
enforce the requirement.

[netdrvr natsemi] Fix RX DMA mapping
RX skbs are always considered maximally sized, until actual reception
of the RX frame occurs. So, update this driver to always map and
unmap a maximally sized skb. This fixes this driver on several
non-x86 platforms.
ATAPI multi-lun support has been broken for a long time.
It used to be that "(drive->id->last_id & 0x7) + 1" was used as
shost->max_lun and the "hdXlun=" kernel parameter could be used to
override this value.
However it was far from optimal:
- people played with "hdXlun=" and then complained about multiple instances
of the same device (most ATAPI drives respond to each LUN)
- probably some devices return 7 not 0 in id->last_id (=> 7 x same device)
This patch from Willem Riede <wrlk@riede.org> fixes it w/o need
for "hdXlun=" option. It was tested by Willem on ATAPI PD/CD drive.
