  parisc: Fix set_fixmap() on PA1.x CPUs (2021-11-01 12:00:22 +0100)

----------------------------------------------------------------
parisc architecture updates for kernel v5.16-rc1

Lots of new features and fixes:
* Added TOC (table of content) support, which is a debugging feature which is
  either initiated by pressing the TOC button or via command in the BMC. If
  pressed the Linux built-in KDB/KGDB will be called (Sven Schnelle)
* Fix CONFIG_PREEMPT (Sven)
* Fix unwinder on 64-bit kernels (Sven)
* Various kgdb fixes (Sven)
* Added KFENCE support (me)
* Switch to ARCH_STACKWALK implementation (me)
* Fix ptrace check on syscall return (me)
* Fix kernel crash with fixmaps on PA1.x machines (me)
* Move thread_info into task struct, aka CONFIG_THREAD_INFO_IN_TASK (me)
* Updated defconfigs
* Smaller cleanups, including Makefile cleanups (Masahiro Yamada),
  use kthread_run() macro (Cai Huoqing), use swap() macro (Yihao Han).
