Here are the powerpc bits to remove TIF_ABI_PENDING now that
set_personality() is called at the appropriate place in exec.

scratch off the Open Firmware device-tree

powerpc: Move cpu hotplug driver lock from pseries to powerpc

2010-01-15T02:26:18+00:00

Move the defintion and lock helper routines for the cpu hotplug driver
lock from pseries to powerpc code to avoid build breaks for platforms
other than pseries that use cpu hotplug.

powerpc: Move /proc/ppc64 to /proc/powerpc update

2010-01-15T02:26:17+00:00

It looks like the previous patch sent out to move RTAS and
other items from /proc/ppc64 to /proc/powerpc missed a few
files needed for RAS and DLPAR functionality.

Original Patch here:
http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-September/076096.html

This patch updates the remaining files to be created under /proc/powerpc.

powerpc/8xx: Fix user space TLB walk in dcbX fixup

2010-01-15T02:26:16+00:00

The newly added fixup for buggy dcbX insn's has
a bug that always trigger a kernel TLB walk so a user space
dcbX insn will cause a Kernel Machine Check if it hits DTLB error.

powerpc: Fix decrementer setup on 1GHz boards

2010-01-15T02:26:15+00:00

We noticed that recent kernels didn't boot on our 1GHz Canyonlands 460EX
boards anymore. As it seems, patch 8d165db1 [powerpc: Improve
decrementer accuracy] introduced this problem. The routine div_sc()
overflows with shift = 32 resulting in this incorrect setup:

time_init: decrementer frequency = 1000.000012 MHz
time_init: processor frequency   = 1000.000012 MHz
clocksource: timebase mult[400000] shift[22] registered
clockevent: decrementer mult[33] shift[32] cpu[0]

This patch now introduces a local div_dc64() version of this function
so that this overflow doesn't happen anymore.

powerpc/swsusp_32: Fix TLB invalidation

2010-01-15T02:20:07+00:00

It seems there is a thinko in the TLB invalidation code that makes the
tlbie in the loop executed just once. The intended check was probably
'gt', not 'lt'.

powerpc/8xx: Always pin kernel instruction TLB

2010-01-15T02:20:07+00:00

Various kernel asm modifies SRR0/SRR1 just before executing
a rfi. If such code crosses a page boundary you risk a TLB miss
which will clobber SRR0/SRR1. Avoid this by always pinning
kernel instruction TLB space.
