Merge tag 'parisc-for-6.4-3' of git://git./linux/kernel/git/deller/parisc-linux

Pull parisc architecture fixes from Helge Deller:
 "Quite a bunch of real bugfixes in here and most of them are tagged for
  backporting: A fix for cache flushing from irq context, a kprobes &
  kgdb breakpoint handling fix, and a fix in the alternative code
  patching function to take care of CPU hotplugging.

  parisc now provides LOCKDEP support and comes with a lightweight
  spinlock check. Both features helped me to find the cache flush bug.

  Additionally writing the AGP gatt has been fixed, the machine allows
  the user to reboot after a system halt and arch_sync_dma_for_cpu() has
  been optimized for PCXL PCUs.

  Summary:

   - Fix flush_dcache_page() for usage from irq context

   - Handle kprobes breakpoints only in kernel context

   - Handle kgdb breakpoints only in kernel context

   - Use num_present_cpus() in alternative patching code

   - Enable LOCKDEP support

   - Add lightweight spinlock checks

   - Flush AGP gatt writes and adjust gatt mask in parisc_agp_mask_memory()

   - Allow to reboot machine after system halt

   - Improve cache flushing for PCXL in arch_sync_dma_for_cpu()"
