For powerpc, s390, x86 and the main uapi linux/kvm.h header, none of
them entail changes in tooling.

To pick up the changes from:
20916d4636a9 ("mm/hugetlb: add mmap() encodings for 32MB and 512MB page sizes")
That do not entail changes in in tools, this just shows that we have to
consider bits [26:31] of flags to beautify that in tools like 'perf
trace'
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/mman.h' differs from latest version at 'include/uapi/linux/mman.h'

Instead of requiring us to go on and edit sources to add new flag.

Now when we run 'make -C tools/perf O=/tmp/build/perf' we end up with:
$ cat /tmp/build/perf/trace/beauty/generated/mmap_flags_array.c
static const char *mmap_flags[] = {
[ilog2(0x40) + 1] = "32BIT",
[ilog2(0x01) + 1] = "SHARED",
[ilog2(0x02) + 1] = "PRIVATE",
[ilog2(0x10) + 1] = "FIXED",
[ilog2(0x20) + 1] = "ANONYMOUS",
[ilog2(0x100000) + 1] = "FIXED_NOREPLACE",
[ilog2(0x0100) + 1] = "GROWSDOWN",
[ilog2(0x0800) + 1] = "DENYWRITE",
[ilog2(0x1000) + 1] = "EXECUTABLE",
[ilog2(0x2000) + 1] = "LOCKED",
[ilog2(0x4000) + 1] = "NORESERVE",
