From: Borislav Petkov bp@suse.de Date: Mon, 12 Feb 2018 21:13:18 +0100 Subject: x86/entry/64: Remove the unused 'icebp' macro
From: Borislav Petkov bp@suse.de
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.
