      Morello: Fix mallocng mmap double slot logic · 4111f17d
      Werner Lewis authored
      GRP_SIZE in Morello is two UNITs, which causes existing logic to fail
      when allocating two slots in a page with zero remainder, as the slot
      and header exceed half the page size. This is modified to allow for
      this case to be correctly supported.

      Morello: Fix mallocng · 0f325712
      Werner Lewis authored
       - Fix size_classes for Morello
       - Fix size_to_class for Morello
      In mallocng, size classes are selected to minimize the remainder in a
      page, with every fourth having zero remainder for allocation of a group
      with one slot. For Morello, the size of the group header is doubled,
      causing the size classes to be misaligned with page boundaries, causing
      errors where alignment is assumed.
      Size classes are adjusted to realign with page boundaries, and a check
      added to prevent out-of-slot offsets.
      Conversion of malloc length to size class is fixed to account for the
      increased group header size for Morello.

      Morello: Add more pthread_cancel tests · 4d2f2c61
      Tamas Petz authored
      These tests now check the following cases:
        1. Async cancellation when a thread is not at a
           cancellation point at the time of a cancel.
        2. Async cancellation when a thread is at a
           cancellation point at the time of a cancel.
        3. Deferred cancellation when a thread is not at a
           cancellation point at the time of a cancel.
        4. Deferred cancellation when a thread is at a
           cancellation point at the time of a cancel.
        5. Async cancellation when cancellation is disabled.
        6. Deferred cancellation when cancellation is disabled.
        7. [extension] Async cancellation with cancellation
        8. [extension] Deferred cancellation with cancellation

      Morello: Fix out of bounds access in mbsrtowcs · 993c9cd5
      Tudor Cretu authored
      Previously, the bitwise operations would detect the null character at
      the end of the string by reading the next 4 chars, even if they were
      out of bounds. This is not allowed in Morello, so a bounds check is
      added before the access. If the next 4 chars access would cross the
      limit of the capability, the algorithm resumes to handling each char
