Razvan Cojocaru 9383de210e x86/altp2m: support for setting restrictions for an array of pages ...

For the default EPT view we have xc_set_mem_access_multi(), which
is able to set an array of pages to an array of access rights with
a single hypercall. However, this functionality was lacking for the
altp2m subsystem, which could only set page restrictions for one
page at a time. This patch addresses the gap.

HVMOP_altp2m_set_mem_access_multi has been added as a HVMOP (as opposed to a
DOMCTL) for consistency with its HVMOP_altp2m_set_mem_access counterpart (and
hence with the original altp2m design, where domains are allowed - with the
proper altp2m access rights - to alter these settings), in the absence of an
official position on the issue from the original altp2m designers.
