Merge tag 'parisc-for-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc architecture updates from Helge Deller:
 "PA-RISC now has a native eBPF JIT compiler for 32- and 64-bit kernels,
  the LED driver was rewritten to use the Linux LED framework and most
  of the parisc bootup code was switched to use *_initcall() functions.

  Summary:

   - add eBPF JIT compiler for 32- and 64-bit kernel

   - LCD/LED driver rewrite to utilize Linux LED subsystem

   - switch to generic mmap top-down layout and brk randomization

   - kernel startup cleanup by loading most drivers via arch_initcall()"
