Hello, all.

This patchset modularizes PMP support and contains the following three
patches.

  mails/0001-libata-separate-PMP-support-code-from-core-code.patch
  mails/0002-libata-implement-PMP-helpers.patch
  mails/0003-libata-make-PMP-support-optional.patch

LLDs which support PMP don't depend on PMP.  If PMP is turned on,
those LLDs support PMP, if PMP is off, they don't.  The size of
libata.ko on x86_64 w all debugging options off change like the
following.

		ON-DISK		LOADED
+SFF+PMP	226k		157k
+SFF-PMP	204k		141k
-SFF+PMP	193k		133k
-SFF-PMP	171k		117k

Both ahci and sata_sil24 have been verified to work w/ PMP turned on
and off.
