[Xen-ia64-devel] [PATCH] Fix domainU boot when VTi domain exists

["Zhang, Xiantao" <xiantao.zhang@xxxxxxxxx>]

        This patch intends to fix domainU boot after VTi domain booted
up.
Currently domainU can't boot after domain VTi booted up. The root cause
is 
when VTi domain exists, after DomU createing and being scheduled for
first time,
context_switch won't be executed completely but through another
execution path
to leave kernel. So iva and pta can't be switched to domU in this case.
This will
lead to LP's(run domU) iva and pta point to VTi domain's ivt and pta. So
when DomainU boots, domain VTi and domainU will hang on one LP.
