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()"
