[PATCH] Kprobes - x86_64 add KPROBE_END macro for .popsection

[S. P. Prasanna]

This patch replace .popsection with the KPROBE_END() macro, as
suggested by Jan Beulich similar to i386 architecture. This will
be helpful for the conversions ike the recent .section -> .pushsection
and .previous -> .popsection to be confined to the header defining
these macros, without need to touch any assembly files.
