Alan Cox 34eeabff5a amd64/arm64 pmap: Stop requiring the accessed bit for superpage promotion 
Stop requiring all of the PTEs to have the accessed bit set for superpage
promotion to occur.  Given that change, add support for promotion to
pmap_enter_quick(), which does not set the accessed bit in the PTE that
it creates.

Since the final mapping within a superpage-aligned and sized region of a
memory-mapped file is typically created by a call to pmap_enter_quick(),
we now achieve promotions in circumstances where they did not occur
before, for example, the X server's read-only mapping of libLLVM-15.so.
