[PATCH v6 0/3] x86,fs/resctrl,arm_mpam: Factor MBA parse-time conversion to be per-arch

Just a small documentation change found by sashiko since v5.

The patches should stay together so please could this all go via tip.

Changelogs in patches.

From cover letter of v3:

This is a new version of Dave Martin's patch [1] to delegate rounding of
bandwidth control user values to the arch code. As there is now more than one
architecture using resctrl, I split the original patch into two, a core resctrl
patch and an x86 patch, and added an MPAM patch. Please let me know if the patch
break down and ordering is sensible and whether the pattern should be followed
for any future similar changes.

This does have a user visible effect on MB schema when using MPAM hardware
with 'bandwidth_gran' greater than 1. I'm not sure if MPAM hardware with such
coarse controls exists in the wild but it is spec compliant and I've tested it
on a model.
