To pick the changes in:
8f0b3cc9a4 ("tcp: RX path for devmem TCP")
That don't result in any changes in the tables generated from that
header.
But while updating I noticed we need to support the new MSG_SOCK_DEVMEM
flag in the hard coded table for the msg flags table, add it.
This silences this perf build warning:
Warning: Kernel ABI header differences:
diff -u tools/perf/trace/beauty/include/linux/socket.h include/linux/socket.h
Please see tools/include/uapi/README for details.
