Subject: x86/entry/64: Remove the unused 'icebp' macro
Git-commit: b498c261107461d5c42140dfddd05df83d8ca078
Patch-mainline: v4.16-rc2
References: bsc#1068032 CVE-2017-5754

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.
