Zhimin Gu 8e5b2a3c5a x86-32/asm/power: Create stack frames in hibernate_asm_32.S ... swsusp_arch_suspend() is callable non-leaf function which doesn't honor CONFIG_FRAME_POINTER, which can result in bad stack traces. Also it's not annotated as ELF callable function which can confuse tooling. Create a stack frame for it when CONFIG_FRAME_POINTER is enabled and give it proper ELF function annotation. Also in this patch introduces the restore_registers() symbol and gives it ELF function annotation, thus to prepare for later register restore. Analogous changes were made for 64bit before in commit ef0f3ed5a4 (x86/asm/power: Create stack frames in hibernate_asm_64.S) and commit 4ce827b4cc (x86/power/64: Fix hibernation return address corruption).
