Subject: [GIT PULL] parisc architecture fixes for kernel v5.15-rc1

Hi Linus,

please pull some more parisc architecture fixes for kernel 5.15-rc1 from:

  http://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git tags/for-5.15/parisc-3

Fixes:
* Build warning fixes in Makefile and Dino PCI driver
* Fix when sched_clock is marked unstable
* Drop strnlen_user() in favour of generic version
* Prevent kernel to write outside userspace signal stack
* Remove CONFIG_SET_FS incl. KERNEL_DS and USER_DS from parisc and switch to
  __get/put_kernel_nofault()

Thanks,
Helge
