            genassym.cf
        src/sys/arch/aarch64/include: frame.h machdep.h

Log Message:
Fix a problem in which a fault occured in an interrupt handler during copyin/copyout was erroneously detected as being occured by copyin.

- keep idepth in faultbuf and compare it to avoid unnecessary fault recovery
- make cpu_set_onfault() nestable to use bus_space_{peek,poke}()
  in hardware interrupt handlers during copyin & copyout.
