Subject: [PATCH 1/3] tracing/trace_stack: fix the number of entries in the header
The last entry in the stack_dump_trace is ULONG_MAX, which is not
a valid entry, but max_stack_trace.nr_entries has accounted for it.
So when printing the header, we should decrease it by one.
Before fix, print as following, for example:
Depth Size Location (53 entries) <--- should be 52
----- ---- --------
0) 3264 108 update_wall_time+0x4d5/0x9a0
...
51) 80 80 syscall_call+0x7/0xb
^^^
it's correct.
