OK, so I normally do my testing using 32-bit kernels under KVM. On a
i386 kernel, running under kvm (again using a Lenovo T540 with a
i7-4900MQ CPU), with the original fast_mix, I get a timestamp count of
166 cycles using a weighted smoothed average. Using your fast_mix2 I
get around 450 cycles.

For architectures that don't have cycle counters, the algorithm for
deciding when to avoid giving entropy credit due to back-to-back timer
interrupts didn't make any sense, since we were checking every 64

We previously extracted a portion of the entropy pool in
mix_pool_bytes() and hashed it in to avoid racing CPU's from returning
duplicate random values. Now that we are using a spinlock to prevent
this from happening, this is no longer necessary. So remove it, to
simplify the code a bit.
In xfer_secondary_pull(), check to make sure we need to pull from the
secondary pool before checking and potentially updating the
last_pulled time.

Hi Rafael,
You can volunteer to take over the maintainership, but then I guess it would
make sense to push this through the PM tree anyway, so please feel free to
send a pull request with those fixes to me.

As suggested by Rafael in [0] I volunteer to take over the orphaned

Small fixes to libkmod, tools and testsuite. The biggest visible change is in
depmod, that now fails if dependency loops are present.

Ah, this addresses my concern about too few interrupts, too. If the
(non-timer) interrupt rate is less than 32/second, you'll never get any
credit.

The node-cur_state and len can be read in a single call of next_entry().
And setting len before reading is a dead write so can be eliminated.

The cond_read_node() should free the given node on error path as it's
not linked to p-cond_list yet. This is done via cond_node_destroy()
but it's not called when next_entry() fails before the expr loop.

I agree with your points, with one exception. Which may be
me misunderstanding.
Also note that the question is not whether the non-timer interrupt
rate is less than 32 seconds, but rather out of the last 64
interrupts, how many of the interrupts come from non-timer sources?
That's not the
