CVS commit: src/sys/kern

["Taylor R Campbell" <riastradh%netbsd.org@localhost>]

Module Name:    src
Committed By:   riastradh
Date:           Wed Apr  8 03:00:31 UTC 2015

Modified Files:
        src/sys/kern: kern_rndq.c

Log Message:
Simplify logic to disable HWRNGs that fail rngtest.

- Mark them RND_FLAG_NO_COLLECT.
- Skip samples from sources marked RND_FLAG_NO_COLLECT.
- Don't ever call rnd_detach_source in softint context.
- Remove bogus use of cpu_softintr_p.

The call to rnd_detach_source in softint can't possibly have ever
worked: if the owner of the source ever tried to detach it by calling
rnd_detach_source again, it would LIST_REMOVE a removed element,
which is broken.
