[PATCH v2 01/14] powerpc: Adopt SYSCALL_DEFINE for arch-specific syscall handlers

Thanks for reviewing my patches.

My reasoning for completing all of these changes in a single patch is for
retaining bisectability. Adopting SYSCALL_DEFINE and COMPAT_SYSCALL_DEFINE
prepends {sys_, compat_sys_} to the symbol names, and so this must be
reflected immediately in the symbol tables.

Sorry, you commented on this in the previous revision, and I should have
acted on it then. I in fact touch all but one usages of ‘asmlinkage’ in arch/powerpc, and so am in a good position to get rid of all of them. I’ll
do that in next revision.
