[PATCH] powerpc: Merged ppc_asm.h
Merged ppc_asm.h between ppc32 & ppc64. The majority of the file is common between the two architectures excluding how a single GPR is saved/restored and which GPRs are non-volatile. Additionally, moved the ASM_CONST macro used on ppc64 into ppc_asm.h. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
