To pick the changes in these csets:

  8eea427b18c0bdb3 ("mm/mempolicy: wire up syscall set_mempolicy_home_node")

That add support for this new syscall in tools such as 'perf trace'.

For instance, this is now possible:

  [root@five ~]# perf trace -e set_mempolicy_home_node
  ^C[root@five ~]#
  [root@five ~]# perf trace -v -e set_mempolicy_home_node
  Using CPUID AuthenticAMD-25-21-0
  event qualifier tracepoint filter: (common_pid != 253729 && common_pid != 3585) && (id == 450)
  mmap size 528384B
  ^C[root@five ~]
  [root@five ~]# perf trace -v -e set*  --max-events 5
  Using CPUID AuthenticAMD-25-21-0
  event qualifier tracepoint filter: (common_pid != 253734 && common_pid != 3585) && (id == 38 || id == 54 || id == 105 || id == 106 || id == 109 || id == 112 || id == 113 || id == 114 || id == 116 || id == 117 || id == 119 || id == 122 || id == 123 || id == 141 || id == 160 || id == 164 || id == 170 || id == 171 || id == 188 || id == 205 || id == 218 || id == 238 || id == 273 || id == 308 || id == 450)
  mmap size 528384B

  [root@five ~]#

That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.
