["Antti Kantee" <pooka%netbsd.org@localhost>]

Module Name:    src
Committed By:   pooka
Date:           Mon Feb 21 20:23:29 UTC 2011

Modified Files:
        src/sys/kern: kern_exec.c kern_exit.c kern_lwp.c
        src/sys/sys: lwp.h

Log Message:
Borrow the lwpctl data area from the parent for the vfork() child.
Otherwise the child will incorrectly see it is not running on any
CPU.  Among other things, this fixes crashes from having
LD_PRELOAD=libpthread.so set in the env.
