This patch series replaces the old non-generic Hardware Random Number
Generator support by a fully generic RNG API.
This makes it possible to register additional RNGs from modules. With this
patch series applied, Laptops with a bcm43xx chip (PowerBook) have a HW RNG
available now.
Additionally two new RNG drivers are added for the "ixp4xx" and "omap"
devices. (Written by Deepak Saxena). This patch series includes the old
patches by Deepak Saxena.
The old x86-rng driver has beed split.
The userspace RNG daemon can later be updated to select the RNG through
/sys/class/misc/hw_random/ for convenience. For now it is sufficient to use
cat and echo -n on the sysfs attributes.

Almost all the code for the VIA RNG is guarded with __i386__ #ifdefs,
the only exception being the enumeration of RNG types which is used to
index into the rng_vector ops array. This patch adds an ifdef around
that for consistency and since the guard makes a difference when adding
new RNG types on non-i386 hardware.

80862430 bridge i810_rng 82801AB PCI Bridge
but it's not listed in rng_pci_tbl[]

Use schedule_timeout_interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.

The dynamic pci id logic has been bothering me for a while, and now that
I started to look into how to move some of this to the driver core, I
thought it was time to clean it all up.
It ends up making the code smaller, and easier to follow, and fixes a
few bugs at the same time (dynamic ids were not being matched
everywhere, and so could be missed on some call paths for new devices,
semaphore not needed to be grabbed when adding a new id and calling the
driver core, etc.)
I also renamed the function pci_match_device() to pci_match_id() as
that's what it really does.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
