Subject: [PATCH] objtool: replace _ASM_PTR with quad in macros
Macros STACK_FRAME_NON_STANDARD and ANNOTATE_NOENDBR uses
_ASM_PTR. It switch between .long and .quad based on 32bit
or 64bit. However objtool doesn't work for 32bit, so _ASM_PTR
makes no sense.
Considering that _ASM_PTR comes from asm.h, which is x86
specific head file, while objtool.h is generic. Replace
_ASM_PTR with quad and remove asm.h reference.
