sh64: Fix up PC casting in unaligned fixup notifier with 32bit ABI.
Presently the build bails with the following: CC arch/sh/mm/alignment.o cc1: warnings being treated as errors arch/sh/mm/alignment.c: In function 'unaligned_fixups_notify': arch/sh/mm/alignment.c:69: warning: cast to pointer from integer of different size arch/sh/mm/alignment.c:74: warning: cast to pointer from integer of different size make[2]: *** [arch/sh/mm/alignment.o] Error 1 This is due to the fact that regs->pc is always 64-bit, while the pointer size depends on the ABI. Wrapping through instruction_pointer() takes care of the appropriate casting for both configurations. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
