[PATCH 2/9] tracing/x86: No need to disable interrupts when calling arch_init_ideal_nop5

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

The function arch_init_ideal_nop5() is taken from the original
ftrace_dyn_arch_init() that originally had interrupts disabled
when calling it. This was due to the old way that mcounts were converted
to nops. The disabling of interrupts is no longer needed for the
work that is done.
