Alan Cox 13de722155 An addendum to r195649, "Add support to the virtual memory system for
configuring machine-dependent memory attributes...":

Don't set the memory attribute for a "real" page that is allocated to
a device object in vm_page_alloc().  It is a pointless act, because
the device pager replaces this "real" page with a "fake" page and sets
the memory attribute on that "fake" page.

Eliminate pointless code from pmap_cache_bits() on amd64.

Employ the "Self Snoop" feature supported by some x86 processors to
avoid cache flushes in the pmap.
