This patch provides an "isp116x-hcd" driver for Philips'
ISP1160/ISP1161 USB host controllers.
The driver:
- is relatively small, meant for use on embedded platforms.
- runs usbtests 1-14 without problems for days.
- has been in use by 6-7 different people on ARM and PPC platforms,
running a range of devices including USB hubs.
- supports suspend/resume of both the platform device and the root hub;
supports remote wakeup of the root hub (but NOT the platform device)
by USB devices.
- does NOT support ISO transfers (nobody has asked for them).
- is PIO-only.

- Adjust slice values
- Instead of one async queue, one is defined per priority level. This
prevents kernel threads (such as reiserfs/x and others) that run at
higher io priority from conflicting with others. Previously, it was a
coin toss what io prio the async queue got, it was defined by who
first set up the queue.
- Let a time slice only begin, when the previous slice is completely
done. Previously we could be somewhat unfair to a new sync slice, if
the previous slice was async and had several ios queued. This might
need a little tweaking if throughput suffers a little due to this,
allowing perhaps an overlap of a single request or so.
- Optimize the calling of kblockd_schedule_work() by doing it only when
it is strictly necessary (no requests in driver and work left to do).
- Correct sync vs async logic. A 'normal' process can be purely async as
well, and a flusher can be purely sync as well. Sync or async is now a
property of the class defined and requests pending. Previously writers
could be considered sync, when they were really async.
- Get rid of the bit fields in cfqq and crq, use flags instead.
- Various other cleanups and fixes

This updates the CFQ io scheduler to the new time sliced design (cfq
v3). It provides full process fairness, while giving excellent
aggregate system throughput even for many competing processes. It
supports io priorities, either inherited from the cpu nice value or set
directly with the ioprio_get/set syscalls. The latter closely mimic
set/getpriority.
This import is based on my latest from -mm.

Add separate files for the different 8250 ISA-based serial boards.
Looking across all the various architectures, it seems reasonable that
we can key the availability of the configuration options for these
beasts to the bus-related symbols (iow, CONFIG_ISA). We also standardise
the base baud/uart clock rate for these boards - I'm sure that isn't
architecture specific, but is solely dependent on the crystal fitted
on the board (which should be the same no matter what type of machine
its fitted into.)

Add support for alternate slave selection algorithms to bonding
balance-xor and 802.3ad modes. Default mode (what we have now: xor of
MAC addresses) is "layer2", new choice is "layer3+4", using IP and port
information for hashing to select peer.
Originally submitted by Jason Gabler for balance-xor mode;
modified by Jay Vosburgh to additionally support 802.3ad mode. Jason's
original comment is as follows:
The attached patch to the Linux Etherchannel Bonding driver modifies the
driver's "balance-xor" mode as follows:
- alternate hashing policy support for mode 2
* Added kernel parameter "xmit_policy" to allow the specification
of different hashing policies for mode 2. The original mode 2
policy is the default, now found in xmit_hash_policy_layer2().
* Added xmit_hash_policy_layer34()
This patch was inspired by hashing policies implemented by Cisco,
Foundry and IBM, which are explained in

Patch from Lennert Buytenhek
All ixdp platforms currently have a cpld mapped in at 0xfafff000.
Since this address is not 1M-aligned, a regular page mapping will be
used instead of a section mapping, which opens up the possibility of
triggering ixp2400 erratum #66 as we only do the XCB=101 workaround
thing for section mappings.
There is still a lot of space higher up in the virtual memory map
for 1M mappings, so move the cpld mapping to 0xfe000000 and make it
1M big so that a section mapping will be used for it.

We never look at it except for the old megaraid driver that abuses it
for sending internal commands. That usage can be fixed easily because
those internal commands are single-threaded by a mutex and we can easily
use a completion there.
