["Thor Lancelot Simon" <tls%netbsd.org@localhost>]

Module Name:    src
Committed By:   tls
Date:           Tue Apr 10 14:02:28 UTC 2012

Modified Files:
        src/sys/kern: kern_rndq.c subr_cprng.c
        src/sys/lib/libkern: arc4random.c
        src/sys/sys: rnd.h

Log Message:
Add a spin mutex to the rndsink structure; it is used to avoid lock
ordering and sleep-holding-locks problems when rekeying, and thus
to avoid a nasty race between cprng destruction and reseeding.
