[Xen-devel] [PATCH 0/4] x86/p2m: use large pages for MMIO mappings

["Jan Beulich" <JBeulich@xxxxxxxx>]

... where possible. This is in response to
http://lists.xenproject.org/archives/html/xen-devel/2015-09/msg01502.html,
albeit only the first three patches are really needed for that (the
fourth one just leverages what the first two do in another way).
The third (main) patch is RFC for a number of reasons - see there.

1: EPT: always return proper order value from ept_get_entry()
2: NPT: always return proper order value from p2m_pt_get_entry()
3: p2m: use large pages for MMIO mappings
4: PoD: shorten updates for certain operations on higher order ranges
