Re: [Xen-devel] [PATCH][discuss] io_apic disable_8254_timer

This patch only adds "disable_8254_timer" and leaves the default as
enabled - ie. There is no "enable_8254_timer" in this patch.  The linux
solution provides more detailed determination of whether to
enable/disable using timer_over_8254, including determining if ATI
chipset is present. Most of which is most likely not necessary with xen
hv at this time.

The added code in this patch could be ifdef 64bit, as the linux solution
is only implemented in the x86_64 io_apic.c code.

Actually this gives me an excuse to pick a scab and get rid of the 'missed tick' logic that relies on that code altogether. So I just deleted the line instead of making it conditional. I'm pretty sure that won't break anything.
