Dave Hansen c0b17b5bd4 x86/mm/pkeys: Dump PKRU with other kernel registers 
Protection Keys never affect kernel mappings.  But, they can
affect whether the kernel will fault when it touches a user
mapping.  The kernel doesn't touch user mappings without some
careful choreography and these accesses don't generally result in
oopses.  But, if one does, we definitely want to have PKRU
available so we can figure out if protection keys played a role.
