When we fork, init_new_context() improperly resets the vdso_base
of the new context to 0. That means that the new process loses
access to the vdso for signal trampolines.
The initialization should be unnecessary anyway as the context
on a fresh mm should be 0 in the first place and binfmt_elf
will initialize that value for a newly loaded process.

from include/asm-powerpc. This is the result of a
mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
