Hi Linus,

please pull two small additional enhancements for this merge window for the
parisc architecture for kernel 5.2 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.2-2

Two small enhancements, which I didn't included in the last pull request
because I wanted to keep them a few more days in for-next before sending
upstream:

- Replace the ldcw barrier instruction by a nop instruction in the CAS code on
  uniprocessor machines.

- Map variables read-only after init (enable ro_after_init feature).

Thanks,
Helge

Hi Linus,

please pull the parisc architecture updates for kernel 5.2:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.2-1


Many great new features, fixes and optimizations, including:

- Convert 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, ...


Thanks,
Helge
