Merge branch 'parisc-5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
"Many great new features, fixes and optimizations, including:
- Convert page table updates to use per-pagetable spinlocks which
overall improves performance on SMP machines a lot, by Mikulas
Patocka
- Kernel debugger (KGDB) support, by Sven Schnelle
- KPROBES support, by Sven Schnelle
- Lots of TLB lock/flush improvements, by Dave Anglin
- Drop DISCONTIGMEM and switch to SPARSEMEM
- Added JUMP_LABEL, branch runtime-patching support
- Lots of other small speedups and cleanups, e.g. for QEMU, stack
randomization, avoidance of name clashes, documentation updates,
etc ..."
