Merge branch 'parisc-5.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
- Optimize parisc page table locks by using the existing
page_table_lock
- Export argv0-preserve flag in binfmt_misc for usage in qemu-user
- Fix interrupt table (IVT) checksum so firmware will call crash
handler (HPMC)
- Increase IRQ stack to 64kb on 64-bit kernel
- Switch to common devmem_is_allowed() implementation
- Minor fix to get_whan()
* 'parisc-5.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
binfmt_misc: pass binfmt_misc flags to the interpreter
parisc: Optimize per-pagetable spinlocks
parisc: Replace test_ti_thread_flag() with test_tsk_thread_flag()
parisc: Bump 64-bit IRQ stack size to 64 KB
parisc: Fix IVT checksum calculation wrt HPMC
parisc: Use the generic devmem_is_allowed()
parisc: Drop out of get_whan() if task is running again
