Subject: [PATCH] uprobes: Move function declarations out of arch
Move the function declarations from the arch headers to the common
header, since only the function bodies are architecture-specific.
These changes are from Vincent Rabin's uprobes patch.
[ oleg: update arch/powerpc/include/asm/uprobes.h ]
