[Xen-devel] RE: [PATCH] clocksource=tsc

["Dan Magenheimer" <dan.magenheimer@xxxxxxxxxx>]

Hmmm... 18055 also fails to boot on my machine.

Could we perhaps fall back to my original patch and do
cleanup later/separately?  I also want to try implementing
an hpet64-based get_s_time() so will be working more
in this code later... but want to get clocksource=tsc
working now with minimal code impact given the freeze.
