[Xen-devel] [RFC 08/22] xen/arm: p2m: Invalidate the TLBs when write unlocking the p2m

2016-07-28 Thread Julien Grall
Sometimes the invalidation of the TLBs can be deferred until the p2m is unlocked. This is for instance the case when multiple mappings are removed. In other case, such as shattering a superpage, an immediate flush is required. Keep track whether a flush is needed directly in the p2m_domain
