Merge branch 'prandom'
prandom fixes/improvements
====================
It would be great if you could still consider this series that fixes and
improves prandom for 3.13. We have sent it to netdev as prandom() originally
came from net/core/utils.c and networking is its main user. For a detailled
description, please see individual patches.
For patch 3 in this series, there will be a minor merge conflict with the
random tree that is for 3.13. See below how to resolve it.
====
Hannes says: on merge with the random tree I would suggest to resolve the
conflict in drivers/char/random.c like this:
if (r->entropy_total > 128) {
r->initialized = 1;
r->entropy_total = 0;
if (r == &nonblocking_pool) {
prandom_reseed_late();
pr_notice("random: %s pool is initialized\n",
r->name);
}
}
So it won't generate a warning if DEBUG_RANDOM_BOOT gets activated.
====
Patch 1 should probably also go to -stable.
Set tested on 32 and 64 bit machines.
Thanks a lot!
