commit cfc515dabe91e3d6c690c68c6a669d6d77fb7ac4

    x86/mm/shadow: spurious warning when unmapping xenheap pages.
    
    Xenheap pages will always have an extra typecount, taken in
    share_xen_page_with_guest(), which doesn't come from a shadow PTE.
    Adjust the warning in sh_remove_all_mappings() to account for it.

    VMX: Always disable SMEP when guest is in non-paging mode
    
    commit e7dda8ec9fc9020e4f53345cdbb18a2e82e54a65
      VMX: disable SMEP feature when guest is in non-paging mode
    
    disabled the SMEP bit if a guest VCPU was using HAP and was not
    in paging mode. However I could observe VCPUs getting stuck in
    the trampoline after the following patch in the Linux kernel
    changed the way CR4 gets set up:
      x86, realmode: read cr4 and EFER from kernel for 64-bit trampoline
    
    The change will set CR4 from already set flags which includes the
    SMEP bit. On bare metal this does not matter as the CPU is in non-
    paging mode at that time. But Xen seems to use the emulated non-
    paging mode regardless of HAP (I verified that on the guests I was
    seeing the issue, HAP was not used).
    
    Therefor it seems right to unset the SMEP bit for a VCPU that is
    not in paging-mode, regardless of its HAP usage.
