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 structure. Make those explicit. This adds one extra __get_user and unrolls a loop. Signed-off-by: NStephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: NPaul Mackerras <paulus@samba.org>
