From 7c4e76935ea24c7c3d282a4832f9e65975eb497d Mon Sep 17 00:00:00 2001 From: Konstantin Belousov Date: Mon, 28 Mar 2016 09:43:40 +0000 Subject: Add defines for the LAPIC TSC deadline timer mode. The LVT timer mode field is two-bit, extend the mask. Also add comments about all MSRs writes to which are not serializing.
