Gcc 4.3 produced this warning:
arch/powerpc/kernel/signal_64.c: In function 'restore_sigcontext':
arch/powerpc/kernel/signal_64.c:161: warning: array subscript is above array bounds
This is caused by us copying to aliases of elements of the pt_regs

This adds one extra __get_user and unrolls a loop.
