#     Merge tag 'trace-v5.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#      "Various tracing fixes:
#     
#        - kbuild found missing define of MCOUNT_INSN_SIZE for various build
#          configs
#     
#        - Initialize variable to zero as gcc thinks it is used undefined (it
#          really isn't but the code is subtle enough that this doesn't hurt)
#     
#        - Convert from do_div() to div64_ull() to prevent potential divide by
#          zero
#     
#        - Unregister a trace point on error path in sched_wakeup tracer
#     
#        - Use signed offset for archs that can have stext not be first
#     
#        - A simple indentation fix (whitespace error)"
#     
#     * tag 'trace-v5.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
#       tracing: Fix indentation issue
#       kernel/trace: Fix do not unregister tracepoints when register sched_migrate_task fail
#       tracing: Change offset type to s32 in preempt/irq tracepoints
#       ftrace: Avoid potential division by zero in function profiler
#       tracing: Have stack tracer compile when MCOUNT_INSN_SIZE is not defined
#       tracing: Define MCOUNT_INSN_SIZE when not defined without direct calls
#       tracing: Initialize val to zero in parse_entry of inject code
