Merge tag 'for-5.19/parisc-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc architecture fixes from Helge Deller:

 - enable ARCH_HAS_STRICT_MODULE_RWX to prevent a boot crash on c8000
   machines

 - flush all mappings of a shared anonymous page on PA8800/8900 machines
   via flushing the whole data cache. This may slow down such machines
   but makes sure that the cache is consistent

 - Fix duplicate definition build error regarding fb_is_primary_device()

* tag 'for-5.19/parisc-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Enable ARCH_HAS_STRICT_MODULE_RWX
