Subject[PATCH 2/4] perf tools: Resolve idle thread cmdline for perf trace
Date
The cmd-trace tool used the cmdline file and resolved the idle thread
using a hardcoded check for the 0 task pid.

Now we have a centralized way to do that from perf using
register_idle_thread() API.

Before:
:0-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name
:0-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name

After:
[idle]-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name
[idle]-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name
