[RFC PATCH v1 0/4] arm_mpam: resctrl: Counter Assignment (ABMC)

[Ben Horgan]

The MPAM counter assignment (ABMC emulation) changes that were dropped from
the resctrl glue series due to some missing precursors in resctrl. Counter
assignement enables bandwidth monitoring in systems that have fewer
monitors than resctrl monitor groups. Posting this as an rfc as this now
depends on two series, the mpam resctrl glue [1] and the resctrl precursors [2].

Based on [1] and [2].
