parisc architecture updates for kernel v5.2

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
