[Xen-devel] [PATCH RFC 06/14] xen: vmx: Added SPP flags in EPT leaf entry.

[Zhang Yi <yi.z.zhang@xxxxxxxxxxxxxxx>]

From: Zhang Yi Z <yi.z.zhang@xxxxxxxxxxxxxxx>

This change also modified the p2m_type width to 5, bits 52:56;
the p2m_access_t bits 60:57, as the bit 61 is hardware using
for EPT leaf entry SPP flags.
