Merge tag 'for-5.18/parisc-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull more parisc architecture updates from Helge Deller:
- Revert a patch to the invalidate/flush vmap routines which broke
kernel patching functions on older PA-RISC machines.
- Fix the kernel patching code wrt locking and flushing. Works now on
B160L machine as well.
- Fix CPU IRQ affinity for LASI, WAX and Dino chips
- Add CPU hotplug support
- Detect the hppa-suse-linux-gcc compiler when cross-compiling
