[PATCH 4.15 067/163] x86/entry/64: Remove the unused icebp macro

From: Greg Kroah-Hartman
Date: Wed Feb 21 2018 - 08:38:51 EST


4.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Borislav Petkov <bp@xxxxxxx>

commit b498c261107461d5c42140dfddd05df83d8ca078 upstream.

That macro was touched around 2.5.8 times, judging by the full history
linux repo, but it was unused even then. Get rid of it already.
