Subject: [PATCH 03/15] cleanup write_tsc
Date: Thu, 20 Dec 2007 18:03:58 -0200 [thread overview]
Message-ID: <11981812041672-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <11981811852758-git-send-email-gcosta@redhat.com>
write_tsc() does not need to be enclosed in any paravirt closure,
as it uses wrmsr(). So we rip off the duplicate in msr.h
and the definition from paravirt.h
