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

[Helge Deller]

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

Well that doesn't work at all.

The *branch* name that you have a few lines lower down in the actual
pull request part ('parisc-5.15-3') does work, but I didn't get the
tag. I suspect you used the branch name because you couldn't get the
wrong tag name to work, and didn't look at why it didn't work.

Because looking closer using 'git ls-remote', it's because your tag
name was bogus. You actually named it 'for-5.13/parisc-3'.

I fixed it up and edited the wrong name after-the-fact, but please be
more careful.

Lovely. Several architectures to go (alpha, arc, csky, h8300, hexagon,
ia64, m68k, microblaze, nds32, nios2, openrisc, sh, sparc, um, and
xtensa) but it's slowly shrinking..

Linus, thanks for fixing it up!
It was actually a copy'n'paste mistake on my side. I used an old
git-tag line from my bash history and missed that it was named
"for-5.13" instead of "for-5.15".
Sorry for that.

That's still quite many... :-)
