Subject: p2m: use correct p2m_type_t in clear_mmio_p2m_entry
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=8adb13efb2d4322df171228f5f85e5fbddb78f99;p=xen.git

p2m: use correct p2m_type_t in clear_mmio_p2m_entry

clear_mmio_p2m_entry() should mark the gfn as invalid.
Use proper name instead of numerical value. The currently used value of
zero means p2m_ram_rw.
