Modified Files:
src/sys/kern: kern_exec.c
Log Message:
In the exec path, multi-LWP programs dispose of their robust futexes
by calling exit_lwps(), except for the last LWP. So, dispose of that
LWP's robust futexes right before calling lwp_ctl_exit().
Fixes a "WARNING: ... : unmapped robust futex list head" message when
running bash under Linux emulation on aarch64.
Root caused and patch proposed by ryo@. I have tweaked it slightly,
just to add a comment and a KASSERT().
