[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-ia64-devel] [PATCH][PVOPS] remove VMX_GUEST/is_inital_xendomain() code
Hi Isaku,
This removes some obvious unused code in the
xen-ia64-domu-minimal-2008mar06 branch. I'm afraid this kind of stuff
will only get in the way for people reviewing domU-only changes.
Thanks,
Alex
