  Tracing fixes for 6.5:

- Fix bad git merge of #endif in arm64 code
  A merge of the arm64 tree caused #endif to go into the wrong place

- Fix crash on lseek of write access to tracefs/error_log
  Opening error_log as write only, and then doing an lseek() causes
  a kernel panic, because the lseek() handle expects a "seq_file"
  to exist (which is not done on write only opens). Use tracing_lseek()
  that tests for this instead of calling the default seq lseek handler.

- Check for negative instead of -E2BIG for error on strscpy() returns
  Instead of testing for -E2BIG from strscpy(), to be more robust,
  check for less than zero, which will make sure it catches any error
  that strscpy() may someday return.
