As we move stuff around, some doc references are broken. Fix some of
them via this script:
./scripts/documentation-file-ref-check --fix
Manually checked if the produced result is valid, removing a few
false-positives.

This will be used by 'perf trace' to show these strings when beautifying
the prctl syscall args. At some point we'll be able to say something
like:
'perf trace --all-cpus -e prctl(option=*SPEC*)'
To filter by arg by name.

To pick up changes from:
2d2123bc7c7f ("arm64/sve: Add prctl controls for userspace vector length management")
7582e22038a2 ("arm64/sve: Backend logic for setting the vector length")
That showed a limitation of the regexp used in tools/perf/trace/beauty/prctl_option.sh,
that matches only PR_{SET,GET}_, but should match a few more, like
PR_MPX_*, PR_CAP_* and the one added by the above commit, PR_SVE_SET_*.
This silences this warning when building tools/perf:
Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h'
Support for those extra prctl options should be left for the next merge
window tho.

Two more, that were just in perf/core and thus weren't covered by Ingo's
latest headers synch, kcmp.h and prctl.h, silencing this:

We will use it to generate tables for beautifying prctl's 'option' arg
and some of the others eventually.
