Subject: [for-linus][PATCH 0/2] tracing: More fixes for v6.15

More tracing fixes for 6.15

- Fix mcount sorttable building for different endian type target

  When modifying the ELF file to sort the mcount_loc table in the
  sorttable.c code, the endianess of the file and the host is used
  to determine if the bytes need to be swapped when calculations are
  done. A change was made to the sorting of the mcount_loc that read
  the values from the ELF file into an array and the swap happened
  on the filling of the array. But one of the calculations of the
  array still did the swap when it did not need to. This caused building
  on a little endian machine for a big endian target to not find
  the mcount function in the 'nm' table and it zeroed it out, causing
  there to be no functions available to trace.

- Add goto out_unlock jump to rv_register_monitor() on error path

  One of the error paths in rv_register_monitor() just returned the
  error when it should have jumped to the out_unlock label to release
  the mutex.
