Hello!
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. This series is based on tip's x86/cache branch: v5.7-rc4-7-g0c4d5ba1b998 and can be retrieved from: git://linux-arm.org/linux-jm.git mpam/cleanup/v4
