[Xen-ia64-devel] [PATCH][Open GFW] Fix windows guest panic in INIT handler

[SUZUKI Kazuhiro <kaz@xxxxxxxxxxxxxx>]

Hi Tristan,

I found that the Windows guest panics when an INIT event is received.
The following patch fixes it. We need to set ar.rsc = 0.

Thanks,
KAZ

Add ar.rsc = 0 so that the Windows guest should not panic when an INIT event
is received.
