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. V1 can be found at: https://lkml.org/lkml/2020/3/6/1249 Based on v5.7-rc6. Changes from V1: ================ 1. Dropped changes to CAT test and CMT test as they will be posted in a later series. 2.
