To pick up changes from:
5d894321c49e6137 ("fs: add atomic write unit max opt to statx")
a516403787e08119 ("fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions")
c07d3aede2b26830 ("fscrypt: add support for hardware-wrapped keys")
These are used to beautify fs syscall arguments, albeit the changes in
this update are not affecting those beautifiers.
This addresses these tools/ build warnings:
Warning: Kernel ABI header differences:

Please see tools/include/uapi/README for details (it's in the first patch
of this series).

It was using the first variation on producing a string representation
for a binary flag, one that used the system's stat.h and preprocessor
tricks that had to be updated everytime a new flag was introduced.
Use the more recent scrape script + strarray +
strarray__scnprintf_flags() combo.
$ tools/perf/trace/beauty/statx_mask.sh
static const char *statx_mask[] = {
[ilog2(0x00000001) + 1] = "TYPE",
[ilog2(0x00000002) + 1] = "MODE",
[ilog2(0x00000004) + 1] = "NLINK",
[ilog2(0x00000008) + 1] = "UID",
[ilog2(0x00000010) + 1] = "GID",
[ilog2(0x00000020) + 1] = "ATIME",
[ilog2(0x00000040) + 1] = "MTIME",
[ilog2(0x00000080) + 1] = "CTIME",
[ilog2(0x00000100) + 1] = "INO",
[ilog2(0x00000200) + 1] = "SIZE",
[ilog2(0x00000400) + 1] = "BLOCKS",
[ilog2(0x00000800) + 1] = "BTIME",
[ilog2(0x00001000) + 1] = "MNT_ID",
[ilog2(0x00002000) + 1] = "DIOALIGN",
[ilog2(0x00004000) + 1] = "MNT_ID_UNIQUE",
};
$
Now we need a copy of uapi/linux/stat.h from tools/include/ in the
scrape only directory tools/perf/trace/beauty/include.
