Use the CFI macros instead of the raw .cfi_* directives to be consistent
with the rest of the VDSO asm. It's also easier on the eyes.
No functional changes.
Although unrelated to the current intent of the patch, a question:
Why does the stub after .Linvoke_userspace_handler in vsgs.S not have CFI
directives ?
Yeah, looks like that stack alignment code needs some CFI.
Actually, this function uses a frame pointer so I think the stack
pointer alignment shouldn't affect the CFI?
You are right. rbx is already handled too with the required CFI in the
prologue.
