Subject[PATCH 0/3] KVM: MMU: fix SMAP virtualization
Date
There are some bugs in current code:
- the PFEC.RSVD is not always true and KVM reuses this bit to cache
CPL and flags.AC bit

- the shadow page will be resued for SMAP enabled and SMAP disabled,
however, user page will be turned to kernel page under some cases
so that SMAP check is missed on that entry

This patchset fixes these bugs and a test case will be posted out soon

KVM: MMU: document smap_andnot_wp
