2.6.12-rc1-pa6 use work queue in LED/LCD driver instead of tasklet.
Main advantage is it allows use of msleep() in the led_LCD_driver to

Optimize ext2_find_next_zero_bit. Gives about 25% perf improvement with a
rsync test with ext3.Signed-off-by: Randolph Chung
fix ext3 performance - ext2_find_next_zero() was culprit.
Kudos to jejb for pointing out the the possibility that ext2_test_bit
and ext2_find_next_zero() may in fact not be enumerating bits in
the bitmap because of endianess. Took sparc64 implementation and
adapted it to our tree. I suspect the real problem is ffz() wants
an unsigned long and was getting garbage in the top half of the
unsigned int. Not confirmed but that's what I suspect.Signed-off-by: Grant Grundler

Fixup bitops.h to use volatile for *_bit() ops
Based on this email thread:
http://marc.theaimsgroup.com/?t=108826637900003In a nutshell:
*_bit() want use of volatile.
__*_bit() are "relaxed" and don't use spinlock or volatile.other minor changes:
o replaces hweight64() macro with alias to generic_hweight64() (Joel Soete)
o cleanup ext2* macros so (a) it's obvious what the XOR magic is about
and (b) one version that works for both 32/64-bit.
o replace 2 uses of CONFIG_64BIT with __LP64__. bitops.h used both.
I think header files that might go to user space should use
something userspace will know about (__LP64__).Signed-off-by: Grant Grundler

Take into account nullified insn and lock functions for profiling
This is needed at the end of functions; it is typical that the return
branch nullifies the next insn, which is in the next function. This
causes profiling data to show up against the "wrong" function.We also count lock times against the locker. This is consistent with
other architectures.Signed-off-by: Randolph Chung

Fix card-mode Dino crashes on 725 (and probably other Snake) systems.
Dino was coming up in fatal mode after a warm reboot. Resetting Dino

I presume firmware does this for us on those.Signed-off-by: Matthew Wilcox

From: Joel Soete
Signed-off-by: Grant GrundlerExplain why we need insert_resource() instead of request_resource().
Fundementally, this is more convoluted for ccio driver because of
o legacy (HP-PB) transperant bridges.
o support for MMIO behind card-mode Dino (PCI)
o support for above bridges without ccio in the boxSBA driver doesn't have to worry about those issues.

2.6.14-rc2-pa2 - make SBA more anal about invalidating pdir entries
Previous code cleared the valid flag a pdir entry but it did NOT
guarantee this change was visible to the PDIR before writing
the PCOM register. Ie the SBA could pick up a stale entry if
the write happened to hit the SBA before the cacheline was flushed
from the cache.Long term, I think I want to make this a compile time flag.
Developement tree should enable anal pdir checking by default
and Debian can disable it with either a CONFIG option
or one-line patch. fdc/sync options can only negatively affect
performance though I haven't measure how much yet.
If someone can run netperf TCP_RR across gige and compare
-pa1 and -pa2, that would be sufficient.Cleaned up the use of "fdc" to make sure it's using "kernel"
space id (specify sr0 but maps to sr4-7). It seems a bit fragile
to assume "sr1" gets loaded with KERNEL_SPACE which is how the
code works today.Tested on 32 and 64-bit SMP kernels on j6k.

2.6.12-rc4-pa2 fix 32-bit support for Astro platforms
o Since my last SBA code change, SBA could allocate more than 1GB of IOVA
space on Astro boxes with more than 1GB of RAM when running 32-bit kernel.
This is bad since IOMMU can only talk to the first 1GB at most.
Kudos to jejb for quickly spotting that bug.o jejb also noted SBA should *always* reject DMA masks > 32-bits since
DMA-mapping.txt indicates caller should try again with 32-bits.o off-by-one error when comparing the mask to IOVA space size.

When I originally moved exit_itimers into __exit_signal, that was the only
place where we could reliably know it was the last thread in the group
dying, without races. Since then we've gotten the signal_struct.live
counter, and do_exit can reliably do group-wide cleanup work.This patch moves the call to do_exit, where it's made without locks. This
avoids the deadlock issues that the old __exit_signal code's comment talks
about, and the one that Oleg found recently with process CPU timers.[ This replaces e03d13e985d48ac4885382c9e3b1510c78bd047f, which is why

Revert commit e03d13e985d48ac4885382c9e3b1510c78bd047f, to be replaced
by a much nicer fix from Roland. -
AMD recently discovered that on some hardware, there is a race condition
possible when a C-state change request goes onto the bus at the same
time as a P-state change request.Both requests happen, but the southbridge hardware only acknowledges the
C-state change. The PowerNow! driver is then stuck in a loop, waiting
for the P-state change acknowledgement. The driver eventually times
out, but can no longer perform P-state changes.It turns out the solution is to resend the P-state change, which the
southbridge will acknowledge normally.Thanks to Johannes Winkelmann for reporting this and testing the fix.

This fixes a stupid typo bug in the iSeries hash table code.
When we place a hash PTE in the secondary bucket, instead of setting the
SECONDARY flag bit, as we should, we (redundantly) set the VALID flag.This was introduced with the patch abolishing bitfields from the hash
table code. Mea culpa, oops. It hasn't been noticed until now because
in practice we don't hit the secondary bucket terribly often.Signed-off-by: David Gibson
