This patch set has several miscellaneous fixes to resctrl selftest tool that are easily visible to user. V1 had fixes to CAT test and CMT test but they were dropped in V2 because having them here made the patchset humongous. So, changes to CAT test and CMT test will be posted in another patchset.
Some warnings reported by sparse tool were fixed in this patchset but some are not yet fixed. They will be fixed in another patchset.
Patches 1 to 14, 18 and 19 are independent fixes. Patches 15 and 16 are preparatory patches for patch 17.
Thanks to Dan and David for reporting couple of issues.

Based on v5.7-rc6.
