src/sys/arch/aarch64/aarch64: db_interface.c
Log Message:
In ddb, fixed "trace/u" and user process memory read/write to work correctly.
In the softint context, curlwp points the kernel lwp, so to get the pmap
of a user process, we had to use curcpu()->ci_onproc->l_proc instead of
curproc (curlwp->l_proc). Adviced by ad@.
