parisc architecture fixes for kernel v5.8

Hi Linus,

please pull two late parisc architecture fixes for kernel 5.8 from:

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.8-2

Two fixes:
- Add the cmpxchg() function for pointers to u8 values. This fixes a kernel linking error when building the tusb1210 driver (from Liam Beguin).
- Add a define for atomic64_set_release() to fix CPU soft lockups which happen because of missing unlocks while processing bit operations (from John David Anglin).

Thanks,
Helge
