different numbers in the comm. In the following example, the
'comm_nodigit' will have samples from all threads starting with
"bpfrb/" into an entry "bpfrb/<N>".

would search the symbol file using the same path of the original file

Per Linus' comments requesting the replacement of "INDIR_BR_LP" in the
indirect branch tracking prctl()s with something more readable, and
suggesting the use of the speculation control prctl()s as an exemplar,
reimplement the prctl()s and related constants that control per-task
forward-edge control flow integrity.
This primarily involves two changes. First, the prctls are
restructured to resemble the style of the speculative execution
workaround control prctls PR_{GET,SET}_SPECULATION_CTRL, to make them
easier to extend in the future. Second, the "indir_br_lp" abbrevation
is expanded to "branch_landing_pads" to be less telegraphic. The
kselftest and documentation is adjusted accordingly.

As it is used only to parse ioctl numbers, not to build perf and so far
no other tools/ living tool uses it, so to clean up tools/include/ to be
used just for building tools, to have access to things available in the
kernel and not yet in the system headers, move it to the directory where
just the tools/perf/trace/beauty/ scripts can use to generate tables
used by perf.

Which entails no changes in the tooling side as it only introduces new

This addresses this perf tools build warning:
diff -u tools/perf/trace/beauty/include/uapi/linux/vhost.h include/uapi/linux/vhost.h
But this specific process, usually boring, this time around catch a
problem, namely the addition of VDPA_GET_VRING_SIZE used an ioctl number
already taken, which went on unnoticed and only got caught when the
tools/perf/trace/beauty/vhost_virtio_ioctl.sh script was run as part of
the perf tools process of updating the tools copies of system headers it
uses for creating id->string tables that, well, broke the perf tools
build because there were multiple initializations in the strings table
for the 0x80 entry...
I'm adding here a link to the discussion, that is lacking in the fix for
the reported problem, and a quote from one of the developers involved:
"Thanks a lot for taking care of this! So given the header is actually
buggy pls hang on to this change until I merge the fix for the header
(you were CC'd on the patch). It's great we have this redundancy which
allowed us to catch the bug in time, and many thanks to Namhyung Kim for
reporting the issue!"
This is here as a hint for anyone thinking about ways to automate
checking these issues in a more automated way... ;-)

It is used only to generate string tables, not to build perf, so move it
to the tools/perf/trace/beauty/include/ hierarchy, that is used just for
scraping.
This is a something that should've have happened, as happened with the
linux/socket.h scrapper, do it now as Ian suggested while doing an
audit/refactor session in the headers used by perf.

No other tools/ living code uses it, just <linux/usbdevice_fs.h> coming
from either 'make install_headers' or from the system /usr/include/
directory.

The only case where it was being used to build was in
tools/perf/trace/beauty/sync_file_range.c, because some older systems
doesn't have the SYNC_FILE_RANGE_WRITE_AND_WAIT define, just use the
system's linux/fs.h header instead, defining it if not available.
