Merge branch 'parisc-5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
- Added fw_cfg support for parisc on qemu
- Added font support in sti text console driver for byte- and word-mode
ROMs
- Switch to more fine grained lws locks and improve spinlock handling
- Add ioread64_hi_lo() and iowrite64_hi_lo() to avoid 0-day linking
errors
- Mark pointers volatile in __xchg8(), __xchg32() and __xchg64() to
help compiler
- Header file cleanups, mostly removal of unused HP-UX compat defines
- Drop one bit from our O_NONBLOCK define to become now 000200000
- Add MAP_UNINITIALIZED define to avoid userspace compile errors
- Drop CONFIG_IDE from defconfigs
- Speed up synchronize_caches() on UP machines
- Rewrite tlb flush threshold calculation
- Comment fixes and cleanups
