parisc architecture updates for kernel v5.9

Hi Linus,

please pull the parisc architecture updates for kernel 5.9-rc1 from:

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.9-1

The majority of the patches are reverts of previous commits regarding the parisc-specific low level spinlocking code and barrier handling, with which we tried to fix CPU stalls on our build servers. In the end John David Anglin found the culprit: We missed a define for atomic64_set_release(). This seems to have fixed our issues, so now it's good to remove the unnecessary code again.

Other than that it's trivial stuff: Spelling fixes, constifications and such.

Thanks,
Helge
