Subject: [GIT PULL v2] parisc architecture fixes for v6.7-rc2

Hi Linus,

please pull three small additional parisc fixes for kernel 6.7-rc2,
two of those are tagged for stable series.

This is v2 of the pull request with the changes to the prctl() patch
as requested by you.

On parisc we still sometimes need writeable stacks, e.g. if programs aren't
compiled with gcc-14. To avoid issues with the upcoming systemd-254 we
therefore have to disable prctl(PR_SET_MDWE) for now (for parisc only).

The other two patches are minor: a bugfix for the soft power-off on qemu
with 64-bit kernel and prefer strscpy() over strlcpy().

Thanks!
Helge
