b4fef22c2fb97fa2 ("uapi: explain how per-syscall AT_* flags should be allocated")

It just moves AT_REMOVEDIR around, and adds a bunch more AT_ for
renameat2() and name_to_handle_at(). We need to improve this situation,
as not all AT_ defines are applicable to all fs flags...
This adds support for those new AT_ defines, addressing this build

Picking the changes from:
37745918e0e7575b ("ALSA: timer: Introduce virtual userspace-driven timers")
Which entails no changes in the tooling side as it only introduces new
SNDRV_TIMER_IOCTL_ ioctls, and the ones tracked by scripts in
tools/perf/trace/beauty/ are only SNDRV_PCM_IOCTL_ and SNDRV_CTL_IOCTL_,
we still need to support SNDRV_TIMER_IOCTL_ ones, but that probably will
be one of the first for a BTF enumeration based approach :-)

There is no scrape script yet for those, but the warning pointed out we
need to update the array with the F_LINUX_SPECIFIC_BASE entries, do it.

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... ;-)

tldr; Just FYI, I'm carrying this on the perf tools tree.
Full explanation:
There used to be no copies, with tools/ code using kernel headers
directly. From time to time tools/perf/ broke due to legitimate kernel
hacking. At some point Linus complained about such direct usage. Then we
adopted the current model.
The way these headers are used in perf are not restricted to just
including them to compile something.
There are sometimes used in scripts that convert defines into string
tables, etc, so some change may break one of these scripts, or new MSRs
may use some different #define pattern, etc.
E.g.:
$ ls -1 tools/perf/trace/beauty/*.sh | head -5
tools/perf/trace/beauty/arch_errno_names.sh
tools/perf/trace/beauty/drm_ioctl.sh
tools/perf/trace/beauty/fadvise.sh
tools/perf/trace/beauty/fsconfig.sh
tools/perf/trace/beauty/fsmount.sh
$
$ tools/perf/trace/beauty/fadvise.sh
static const char *fadvise_advices[] = {
[0] = "NORMAL",
[1] = "RANDOM",
[2] = "SEQUENTIAL",
[3] = "WILLNEED",
[4] = "DONTNEED",
[5] = "NOREUSE",
};
$
The tools/perf/check-headers.sh script, part of the tools/ build
process, points out changes in the original files.
So its important not to touch the copies in tools/ when doing changes in
the original kernel headers, that will be done later, when
check-headers.sh inform about the change to the perf tools hackers.

b841b901c452d926 ("net: Declare MSG_SPLICE_PAGES internal sendmsg() flag")
That don't result in any changes in the tables generated from that
header.
But while updating I noticed we were not handling MSG_BATCH and MSG_ZEROCOPY in the
hard coded table for the msg flags table, add them.

Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned
up. Things were converted to use MSG_MORE instead, but the protocol
sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now
unnecessary.

A table generator for setsockopt is needed, probably will be done in the

e.g:

static const char *socket_families[] = {
[0] = "UNSPEC",
[1] = "LOCAL",
[2] = "INET",
[3] = "AX25",
[4] = "IPX",
[5] = "APPLETALK",
[6] = "NETROM",
[7] = "BRIDGE",
[8] = "ATMPVC",
[9] = "X25",
[10] = "INET6",
[11] = "ROSE",
[12] = "DECnet",
[13] = "NETBEUI",
[14] = "SECURITY",
[15] = "KEY",
[16] = "NETLINK",
[17] = "PACKET",
[18] = "ASH",
[19] = "ECONET",
[20] = "ATMSVC",
[21] = "RDS",
[22] = "SNA",
[23] = "IRDA",
[24] = "PPPOX",
[25] = "WANPIPE",
[26] = "LLC",
[27] = "IB",
[28] = "MPLS",
[29] = "CAN",
[30] = "TIPC",
[31] = "BLUETOOTH",
[32] = "IUCV",
[33] = "RXRPC",
[34] = "ISDN",
[35] = "PHONET",
[36] = "IEEE802154",
[37] = "CAIF",
[38] = "ALG",
[39] = "NFC",
[40] = "VSOCK",
[41] = "KCM",
[42] = "QIPCRTR",
[43] = "SMC",
[44] = "XDP",
};
$
This uses a copy of include/linux/socket.h that is kept in a directory
to be used just for these table generation scripts and for checking if
the kernel has a new file that maybe gets something new for these
tables.
This allows us to:
- Avoid accessing files outside tools/, in the kernel sources, that may
be changed in unexpected ways and thus break these scripts.
- Notice when those files change and thus check if the changes don't
break those scripts, update them to automatically get the new
definitions, a new socket family, for instance.
- Not add then to the tools/include/ where it may end up used while
building the tools and end up requiring dragging yet more stuff from
the kernel or plain break the build in some of the myriad environments
where perf may be built.
This will replace the previous static array in tools/perf/ that was
dated and was already missing the AF_KCM, AF_QIPCRTR, AF_SMC and AF_XDP
families.
The next cset will wire this up to the perf build process.
At some point this must be made into a library to be used in places such
as libtraceevent, bpftrace, etc.
