To pick the changes in:

  f94fd25cb0aaf77f ("tcp: pass back data left in socket after receive")

That don't result in any changes in the tables generated from that
header.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/perf/trace/beauty/include/linux/socket.h' differs from latest version at 'include/linux/socket.h'

To pick the changes in:

  a6a6fe27bab48f0d ("net/smc: Dynamic control handshake limitation by socket options")

This automagically adds support for the SOL_MNC socket level:

  $

This will allow 'perf trace' to translate 286 into "SMC" as is done with
the other socket levels:

<title>perf beauty: Make the prctl arg regexp more strict to cope with PR_SET_VMA</title>

<link rel='alternate' type='text/html' href='https://git.zx2c4.com/linux-dev/commit/?id=100198322b2eb7fb38750cb0fcae5cd533907410'/>
<id>urn:sha1:100198322b2eb7fb38750cb0fcae5cd533907410</id>
<content type='text'>
This new PR_SET_VMA value isn't in sequence with all the other prctl
arguments and instead uses a big, 0x prefixed hex number: 0x53564d41 (S V M A).

This makes it harder to generate a string table as it would be rather
sparse, so make the regexp more stricter to avoid catching those.

A followup patch for 'perf trace' to cope with such oddities will be
needed, but then its a matter for the next merge window.

The next patch will update the prctl.h file to cope with this perf build
warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h'
  diff -u tools/include/uapi/linux/prctl.h include/uapi/linux/prctl.h

<title>perf beauty: Add socket level scnprintf that handles ARCH specific SOL_SOCKET</title>

<id>urn:sha1:66aee54ba42c72d594076f1de2d97fe0933836e8</id>
<content type='text'>
SOL_SOCKET has a different value according to the architecture, some
have it as 0xffff while all the others have it as 1, so a simple string
array isn't usable, add a scnprintf routine that treats it as a special
case, using the array for other values.
