Hello,
Sorry I missed that patch. In the future, please CC me if you want a
patch to go in Xen 4.9.

The same set of functions is used to set as well as to clean
P2M entries, except that for clean operations INVALID_MFN (~0UL)
is passed as a parameter. Unfortunately, when calculating an
appropriate target order for a particular mapping INVALID_MFN
is not taken into account which leads to 4K page target order
being set each time even for 2MB and 1GB mappings. This eventually
breaks down an EPT structure irreversibly into 4K mappings which
prevents consecutive high order mappings to this area.
It sounds like we have a similar issue on ARM as I wrote the
implementation based on the x86 code. I will send a patch.
