[PATCH v3 00/11] target/arm mte fixes
Posted by Richard Henderson 1 year, 4 months ago
Changes for v3:
  * linux-user mprotect fix moved to start, just to get it out
    of the way while I reworked the others.

  * Patch 2, the fix for unaligned accesses, has been split into 9.
    Hopefully these are much easier to review than previously.

    Technically only patches 1-6,11 are required for bug fixing.
    Patches 7-10 are only cleanups, but I think they're important
    for clarity post bug fixing.

... and it fails all of the kasan unit tests.
I'll have to investigate more next week.
