  parisc: remove ARCH_DEFCONFIG (2021-12-22 09:02:10 +0100)

----------------------------------------------------------------
parisc architecture late bug fixes for kernel v5.16

- Fix a bug in the C code which calculates the relevant futex spinlock based on
  the futex virtual address. In some cases a wrong spinlock (compared to what
  is calculated in the assembly code path) was choosen which then can lead to
  deadlocks.

- The 64-bit kernel missed to clip the LWS number in the Light-weight-syscall
  path for 32-bit processes.

- Prevent CPU register dump to show stale value in IIR register on access rights traps.

- Remove unused ARCH_DEFCONFIG entries.

----------------------------------------------------------------
Helge Deller (1):
      parisc: Clear stale IIR value on instruction access rights trap

John David Anglin (2):
      parisc: Correct completer in lws start
      parisc: Fix mask used to select futex spinlock

      parisc: remove ARCH_DEFCONFIG
