Subject: [GIT PULL] parisc architecture updates for kernel v5.12-rc1

Hi Linus,

please pull the parisc architecture updates for kernel 5.12-rc1 from:

  http://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.12-1

Updates include:
* 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()

Thanks,
Helge
