From 09933ee55d2ae2592d66ee9c6f92a2e139625061 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 28 Mar 2011 12:07:52 +0100 Subject: [PATCH] x86: cleanup after tboot fix (c/s 23101:dd386a4b6595) When submitting the patch that became 23101:dd386a4b6595 I forgot that I actually intended to remove the pointless IRQ disabling and restoring (and the then pointless comment). Pointless because the code, other than its pre-23013:65d26504e843 original, now runs before interrupts get enabled for the first time.
