RE: [Xen-ia64-devel] [PATCH] [RESEND] domU destroy & page ref counter

["Xu, Anthony" <anthony.xu@xxxxxxxxx>]

This patch is really good, community has been waiting domain destroy patch for 
a long time.

Is it appropriate time to flush vhpt and machine tlb when destroying domain?
I have below concerns,
1. This may counteract the benefit of rid partition. In my mind these flushes 
are done only when rid reuse happens when allocating rid for a new domain.
2. When migration is enabled, VMM may need to flush vhpt and TC in all 
processors.

Thanks,
-Anthony
