Hi, this patch tries to make vtlb/vhpt management interface cleaner. No new features added. It also allow to flush region 7 (which fixes a bug). We really have to think on domain_dirty_cpumask and tlb_flush_mask. Currently, domain_dirty_cpumask is never set. Setting it kills performance. Tested by boot+halt of dom0+domU SMP. Tristan.
