[v2,0/8] selftests/mm fixes for arm64

Message

Hi All,

This is v2 of my series to clean up mm selftests so that they run correctly on
arm64. See [1] for full explanation.


Changes Since v1 [1]
--------------------

  - Patch 1: Explicitly set line buffer mode in ksft_print_header()
  - Dropped v1 patch 2 (set execute permissions): Andrew has taken this into his
    branch separately.
  - Patch 2: Don't compile `soft-dirty` suite for arm64 instead of skipping it
    at runtime.
  - Patch 2: Declare fewer tests and skip all of test_softdirty() if soft-dirty
    is not supported, rather than conditionally marking each check as skipped.
  - Added Reviewed-by tags: thanks DavidH!
  - Patch 8: Clarified commit message.
