Merge tag 'for-5.18/parisc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc architecture updates from Helge Deller:
- add vDSO support (allows us to use non-executable stacks)
- many TLB and cache flush optimizations (by Dave Anglin)
- fix handling of probe non-access faults (by Dave Anglin)
- fix invalidate/flush vmap routines (by Dave Anglin)
- avoid using hardware single-step in kprobes
- enable ARCH_HAS_DEBUG_VM_PGTABLE
- many cleanups in unaligned handlers, e.g. rewrite of existing
assembly code
- always use the self-extracting kernel feature
- big refacturing and code reductions regarding space-register usage in
get_user() and put_user()
- add fillrect() support to stifb graphics driver
