Module Name:    src
Committed By:   ryo
Date:           Tue Feb 23 14:50:33 UTC 2021

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.
