powerpc: make ARCH=ppc use arch/powerpc/kernel/process.c
Commit 5388fb1025443ec223ba556b10efc4c5f83f8682 made signal_32.c use discard_lazy_cpu_state, which broke ARCH=ppc because that uses the common signal_32.c but has its own process.c. Make ARCH=ppc use the common process.c to fix this and to reduce the amount of duplicated code. Signed-off-by: Paul Mackerras <paulus@samba.org>
