rand_initialize_irq() was removed here:
commit 946672f548682905d8ecdab33bb6e2c705418505
"random: remove rand_initialize_irq()"
The AB3100 mfd-driver is the only driver still using it and breaks
with the following error-messages in linux-next (next-20120717):
...
drivers/built-in.o: In function `ab3100_probe':
ab3100-core.c:(.devinit.text+0xbf97): undefined reference to `rand_initialize_irq'
Fix this issue and remove all remaining relicts of rand_initialize_irq().
Might be worth to fold-in these changes into the original commit.
Tested against linux-next (next-20120717) on a Ubuntu/precise AMD64 host.

Oops. Sorry, I thought I had caught all of the users of
rand_initialize_irq(). Thanks for catching this!
I'll take your advice and merge it into the original commit.

Yes, there was a huge discussion on LKML about two weeks ago. The
key commit that will be going in during the next merge window is:
http://git.kernel.org/?p=linux/kernel/git/tytso/random.git;a=commitdiff;h=775f4b297b780601e61787b766f306ed3e1d23eb
There are a whole lot of other changes, of course, but that's the key
change which IRQF_SAMPLE_RANDOM a no-op. People have tested this
under extreme conditions (high speed networking tests with no
interrupt mitigations, etc.) and the patch as tweaked had no
measurable overhead, so we can simply sample every single commit with
a low-overhead fast path which uses per-cpu buffers, and then mix into
the /dev/random entropy pool less frequently (which is still fast, but
requires a few more memory accesses to shared memory that may incur
delays due to cache line bounces).
