Jason A. Harmening fa4e4d55b3 Clean up a couple of MD warts in vm_fault_populate(): 
--Eliminate a big ifdef that encompassed all currently-supported
architectures except mips and powerpc32.  This applied to the case
in which we've allocated a superpage but the pager-populated range
is insufficient for a superpage mapping.  For platforms that don't
support superpages the check should be inexpensive as we shouldn't
get a superpage in the first place.  Make the normal-page fallback
logic identical for all platforms and provide a simple implementation
of pmap_ps_enabled() for MIPS and Book-E/AIM32 powerpc.

--Apply the logic for handling pmap_enter() failure if a superpage
mapping can't be supported due to additional protection policy.
Use KERN_PROTECTION_FAILURE instead of KERN_FAILURE for this case,
and note Intel PKU on amd64 as the first example of such protection
policy.
