This is the same as v3 but has two added patches related to continuing
after counter assignment and one related to the meaning of the tasks
file. The last one is doesn't strictly belong here but I thought it best to
keep things together.
(Also, a tiny commit message line wrap adjustment.)

Description from the previous versions cover letter:

A little bit of preparatory work to get ready for MPAM counter
assignment. Resctrl gained support last year for counter assignment for AMD
machines supporting ABMC. Tighten a few things up, that weren't needed for
AMD, so that the MPAM driver can emulate ABMC and hence support counter
assignment.

Based on v7.0-rc4.
