Linus,

tracing fixes for 7.1:

- Add more functions to the remote allowed list

  randconfig found more functions that are allowed for the remote code for
  s390 and arm. Add them to the allowed list.

- Fix remote_test error path

  If one of the simple ring buffers fails to load, the code is supposed to
  rollback its initialized buffers. Instead of rolling back the buffers for
  the failed load, it uses the global variable and rolls back all the
  successfully loaded buffers.


Please pull the latest trace-v7.1-rc3 tree, which can be found at:
