  • Thread-topic: [Xen-ia64-devel][PATCH] Fix a bug about set_rse_reg

When setting rse register, XEN needs to modify banking store memory.
This operation can't be interrupted, otherwise contents of
stack registers may be destroyed.

BTW, after this patch, crashme can pass on SMP VTI-domain.

Thanks,
