[PATCH v3 0/4] x86/P2M: allow 2M superpage use for shadowed guests
I did notice this anomaly in the context of IOMMU side work.

1: shadow: slightly consolidate sh_unshadow_for_p2m_change() (part I)
2: shadow: slightly consolidate sh_unshadow_for_p2m_change() (part II)
3: shadow: slightly consolidate sh_unshadow_for_p2m_change() (part III)
4: P2M: allow 2M superpage use for shadowed guests

FWIW I think that adding some kind of mfn_mask() opreration would
be neater and more understandable than subtracting the PSE flag.

Cheers,
