These are the miscellaneous cleanup patches that floated to the top of the MPAM tree. The only interesting thing are the patches to make the AMD/Intel differences something resctrl understands, instead of just 'happening' because of the different function pointers. This will become more important once MPAM support is added. parse_bw() and friends are what enforces resctrl's ABI. Allowing an architecture/platform to provide a subtly different function here would be bad for user-space. MPAM would set arch_has_sparse_bitmaps and arch_has_empty_bitmap, but not arch_needs_linear. Since [v3], some spurious brackets have disappears, comments have moved to the correct orrder, and tags collected. Since [v2], arch_has_empty_bitmap has been added, and some typos fixed. Since [v1], I've picked up all the review feedback and collected the tags. Nothing in this series should change any behaviour.
