Merge tag 'for-5.16/parisc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
"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)"
