From bb9d3e473d5b324907e15dff4e54410b28ea50e2 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 3 Aug 2012 15:26:50 +0200 Subject: [PATCH] x86, microcode: Drop uci->mc check on resume path Remove the uci->mc check on the cpu resume path because the low-level drivers do that anyway. More importantly, though, this fixes a contrived and obscure but still important case. Imagine the following: * boot machine, no new microcode in /lib/firmware * a subset of the CPUs is offlined * in the meantime, user puts new fresh microcode container into /lib/firmware and reloads it by doing $ echo 1 > /sys/devices/system/cpu/microcode/reload * offlined cores come back online and they don't get the newer microcode applied due to this check. Later patches take care of the issue on AMD. While at it, cleanup code around it.
