[Xen-devel] [PATCH 0/1] Prevent one cause of "MP-BIOS bug: 8254 timer"... message from linux

[Don Slutz <dslutz@xxxxxxxxxxx>]

Based on the proposed fix in QEMU:

That was provided for:

http://marc.info/?l=qemu-devel&m=139295851107140&w=2

Which is very close to a bug I have been looking into and asked some
questions about in:

http://lists.xen.org/archives/html/xen-devel/2014-02/msg01787.html

I came up with this change.  It does look like vpt does support
starting a timer in the past and what happens is based on the
setting of timer_mode.  Since real hardware does not support this
and this is the simpler change I went this way.
