Subject: [PATCH 1/2 v2] x86,tsc: Use cpu id defines from intel-family.h
Date: Mon, 19 Sep 2016 08:51:40 -0400	[thread overview]
Message-ID: <1474289501-31717-2-git-send-email-prarit@redhat.com> (raw)
In-Reply-To: <1474289501-31717-1-git-send-email-prarit@redhat.com>

asm/intel-family.h contains defines for cpu ids which should be
used in the native_calibrate_tsc() function.
