[PATCH] EFI x86: pass firmware call parameters on the stack
When calling into the EFI firmware, the parameters need to be passed on the stack. The recent change to use -mregparm=3 breaks x86 EFI support. This patch is needed to allow the new Intel-based Macs to suspend to ram (efi.get_time is called during the suspend phase).
