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)"
