Merge tag 'parisc-for-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc architecture updates and fixes from Helge Deller:
"Fixes for the IPv4 and IPv6 checksum functions, a fix for the 64-bit
unaligned memory exception handler and various code cleanups.
Most of the patches are tagged for stable series.
- Fix inline assembly in ipv4 and ipv6 checksum functions (Guenter
Roeck)
- Rewrite 64-bit inline assembly of emulate_ldd() (Guenter Roeck)
- Do not clobber carry/borrow bits in tophys and tovirt macros (John
David Anglin)
- Warn when kernel accesses unaligned memory"
