From acd58a3ad0ed5875fb88bbb078309a3d7ee147a0 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 30 Apr 2015 09:17:50 +0200 Subject: [PATCH] x86/fpu: Remove run-once init quirks Remove various boot quirks that came from the old code. The new code is cleanly split up into per-system and per-cpu init sequences, and system init functions are only called once. Remove the run-once quirks.
