Subject[PATCH] x86-64: fix ordering of CFI directives and recent ASM_CLAC additions
While these got added in the right place everywhere else, entry_64.S
is the odd one where they ended up before the initial CFI directive(s).
In order to cover the full code ranges, the CFI directive must be
first, though.
