Having thought about it more I'm not sure this is correct. I think we should make the default case VM_MEMATTR_DEVICE. EFI_MD_ATTR_WC Is also wrong as it should be VM_MEMATTR_UNCACHEABLE so should be fixed at some stage.

This revision now requires changes to proceed.May 22 2019, 12:19 PM

Default to DEVICE and while here check is XP atttribute is set and set UXN/PXN if it is.
