We have had complaints where a threaded application is left in a bad state
after one of it's threads is killed when we hit a VM: out_of_memory
condition.Killing just one of the process threads can leave the application in a bad
state, whereas killing the entire process group would allow for the
application to restart, or be otherwise handled, and makes it very obvious
that something has gone wrong.This change allows the entire process group to be taken down, rather
than just the one thread.Signed-off-by: Will Schmidt

Commit 8112753bb2c0045398c89d0647792b39805f6d40 made 44x in
ARCH=powerpc builds use cpu setup routines in cpu_setup_44x.S,
but didn't make a similar change for ARCH=ppc, and consequently
the ARCH=ppc builds fail with undefined symbols (since both use
the same cputable.c).This fixes it by including cpu_setup_44x.S in the ARCH=ppc builds,
and by taking out the now-redundant FPU initialization in
arch/ppc/kernel/head_44x.S.Signed-off-by: Paul Mackerras

cpm_dpram_addr returns physical memory of the DP RAM instead of
iomapped virtual memory. As there usually is a 1:1 MMU map of
the IMMR area, this is often not noticed. However, cpm_dpram_phys
assumes this iomapped virtual memory and returns garbage on the
1:1 mapped memory causing CPM1 uart console to fail.This patch fixes the problem (copied from the powerpc tree).

Instantiation of 8MB pages on the TLB cache for the kernel static
mapping trashes r3 register on !CONFIG_8xx_CPU6 configurations.
This ensures r3 gets saved and restored.This has been posted to linuxppc-embedded by Marcelo Tosatti
, but only an incomplete version of the patch
has been applied in c51e078f82096a7d35ac8ec2416272e843a0e1c4.

The 440 family of processors don't have a tlbie instruction. So, we
implement TLB invalidates by explicitly searching the TLB with tlbsx.,
then clobbering the relevant entry, if any. Unfortunately the PID for
the search needs to be stored in the MMUCR register, which is also
used by the TLB miss handler. Interrupts were enabled in _tlbie(), so
an interrupt between loading the MMUCR and the tlbsx could cause
incorrect search results, and thus a failure to invalide TLB entries
which needed to be invalidated.This fixes the problem in both arch/ppc and arch/powerpc by inhibiting
interrupts (even critical and debug interrupts) across the relevant
instructions.Signed-off-by: David Gibson

per cpu data section contains two types of data. One set which is
exclusively accessed by the local cpu and the other set which is per cpu,
but also shared by remote cpus. In the current kernel, these two sets are
not clearely separated out. This can potentially cause the same data
cacheline shared between the two sets of data, which will result in
unnecessary bouncing of the cacheline between cpus.One way to fix the problem is to cacheline align the remotely accessed per
cpu data, both at the beginning and at the end. Because of the padding at
both ends, this will likely cause some memory wastage and also the
interface to achieve this is not clean.This patch:
Moves the remotely accessed per cpu data (which is currently marked
as ____cacheline_aligned_in_smp) into a different section, where all the data
elements are cacheline aligned. And as such, this differentiates the local
only data and remotely accessed data cleanly.Signed-off-by: Fenghua Yu
