Konstantin Belousov c08973d09c Workaround for Intel SKL002/SKL012S errata. 
Disable the use of executable 2M page mappings in EPT-format page
tables on affected CPUs.  For bhyve virtual machines, this effectively
disables all use of superpage mappings on affected CPUs.  The
vm.pmap.allow_2m_x_ept sysctl can be set to override the default and
enable mappings on affected CPUs.

Alternate approaches have been suggested, but at present we do not
believe the complexity is warranted for typical bhyve's use cases.
