In the first case there is an additional complication if CR4.SMEP is

enabled: since we've turned the page into a kernel page, the kernel may now

execute it.  We handle this by also setting spte.nx.  If we get a user

fetch or read fault, we'll change spte.u=1 and spte.nx=gpte.nx back.

In the first case there are two additional complications:

- if CR4.SMAP is disabled: since the page has been changed to a kernel

  page, it can not be reused when CR4.SMAP is enabled. We set

  CR4.SMAP && !CR0.WP into shadow page's role to avoid this case. Note,

  here we do not care the case that CR4.SMAP is enabled since KVM will

  directly inject #PF to guest due to failed permission check.



To prevent an spte that was converted into a kernel page with cr0.wp=0

from being written by the kernel after cr0.wp has changed to 1, we make
