Linus Torvalds 8066178f53 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.
