Modified Files:
src/sys/arch/aarch64/aarch64: idle_machdep.S
Log Message:
Just a few optimizations.
- in cpu_idle(), ci_intr_depth is always 0, so there is no need to fetch for
increment or conditional branch.
- curcpu() is immutable in idle lwp, there is no need to consider KPREEMPT.
Therefore, get curcpu() first and keep using it.
- add more comment.
