This patch fixes the following warnings. The first ones are leftovers
from when __get_user() was replaced by probe_kernel_address().
The last one is from when show_user_instructions() was added.
arch/powerpc/kernel/process.c:1287:22: warning: incorrect type in argument 2
(different address space
When two processes crash at the same time, we sometimes encounter
interleaving in the middle of a line:
[4.365317] init[1]: segfault (11) at 0 nip 0 lr 0 code 1
[4.370452] init[1]: code:
[4.372042] init[74]: segfault (11) at 10a74 nip 1000c198 lr 100
instructions_to_print var is assigned value 16 and there is no
way to change it.
This patch replaces it by a constant.

It is a bit of a hack, agreed. What we do is
WARN_ON() already contains an unlikely(), so it's not necessary to
wrap it into another.

Hello
This patchset adds a new set of functions which are open-coded in lot of
place.
Basicly the pattern is always the same, "read, modify a bit, write"
some driver already have thoses pattern them as functions. (like ahci_sunxi.c
or dwmac-meson8b)
The first patch rename some powerpc funtions w

Since setbits32/clrbits32 work on be32, it's better to remove ambiguity on
the used data type.

If you are going to do this, please add for_each_set_bit64() and similar.
