Here's v1.1: --- From: Borislav Petkov Date: Sun, 18 Dec 2016 12:05:50 +0100 Subject: [PATCH -v1.1 03/13] x86/microcode/AMD: Clean up find_equiv_id() No need to have it marked "inline" - let gcc decide. Also, shorten the argument name and simplify while-test. While at it, make it into a proper for-loop and simplify it even more, as tglx suggests. No functionality change.
