This patch includes minor "sparse -Wbitwise" updates for the PCI based
HCDs. Almost all of them involve just changing the second parameter of the
suspend() method to a pm_message_t ... the others relate to how the EHCI
code walks in-memory data structures. (There's a minor bug fixed there too
... affecting the big-endian sysfs async schedule dump.)

===================================================================
This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t". This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:
- <linux/usb.h> and usbcore, signature change
- Some drivers only changed the signature, net effect this just
shuts up "sparse -Wbitwise":
* hid-core
* stir4200
- Two network drivers did that, and also grew slightly more
featureful suspend code ... they now properly shut down
their activities. (As should stir4200...)
* pegasus
* usbnet
Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

This has a variety of updates to the shared suspend/resume code for
PCI based USB host controllers.
- Cope with pm_message_t replacing the target system state.
This is actually a loss of functionality; PCI D1 and D2
states will no longer be used, and it's no longer knowable
that D3cold is on the way so power will be lost.
- Most importantly, some of the resume paths are reworked and
cleaned up. They're now an exact mirror of suspend paths,
and more care is taken to ensure the hardware is reactivated
before the hardware re-enables interrupts.
Plus comment and diagnostic cleanups; there are some nasty cases here
especially combined with swsusp, now they're somewhat commented.

Don't use cmd->request->nr_hw_segments as it may not be initialized
(SG_IO in particular bypasses anything that initializes this and just
uses scsi_do_req to insert a scsi_request directly on the head of the
queue) and a bogus value here can trip up the checks to make sure that
the number of segments will fit in the queue ring buffer, resulting in
commands that are never completed.
Fix up several issues with PCI DMA mapping and failure to check return
values on the mappings.
Make the check for space in the ring buffer happen after the DMA mapping
is done since any checks done before the mapping has taken place are
bogus.

Tavor, MTTs for FMR are separate from regular MTTs, and are reserved at driver

map the MTTs. For Arbel, there's no such limitation, and all MTTs and MPTs

Fix bug in MTT allocation in mem-free mode.
I misunderstood the MTT size value returned by the firmware -- it is really
the size of a single MTT entry, since mem-free mode does not segment the MTT
as the original firmware did. This meant that our MTT addresses ended up
being off by a factor of 8. This meant that our MTT allocations might
overlap, and so we could overwrite and corrupt earlier memory regions when
writing new MTT entries.
We fix this by always using our 64-byte MTT segment size. This allows some
simplification of the code as well, since there's no reason to put the MTT
segment size in a variable -- we can always use our enum value directly.

- plug various leaks and use after frees in the remove and
initialization failure path (some still left)
- remove useless global list of boards and use pci_set_drvdata instead
- unobsfucate init path by merging functions together
- kill various totally useless state variables
- .. probably more I forgot
Note that the tty part still generates lots of sparse warnings and there's
still a totally useless layer of function pointer indirections, but maybe
someone else will fix that bit up.

In function __generic_unplug_device(), kernel can use a cheaper function
elv_queue_empty() instead of more expensive elv_next_request to find
whether the queue is empty or not. blk_run_queue can also made conditional
on whether queue's emptiness before calling request_fn().

There is a possibility that a bio will be accessed after it has been freed
on SCSI. It happens if you submit a bio with BIO_SYNC marked and the
auto-unplugging kicks the request_fn, SCSI re-enables interrupts in-between
so if the request completes between the add_request() in __make_request()
and the bio_sync() call, we could be looking at a dead bio. It's a slim
race, but it has been triggered in the Real World.
So assign bio_sync() to a local variable instead.

My previous patch that added sleep support for uninorth-agp and some AGP
"off" stuff in radeonfb and aty128fb is breaking some configs. More
specifically, it has problems with rage128 setups since the DRI code for
these in X doesn't properly re-enable AGP on wakeup or console switch
(unlike the radeon DRM).
This patch fixes the problem for pmac once for all by using a different
approach. The AGP driver "registers" special suspend/resume callbacks with
some arch code that the fbdev's can later on call to suspend and resume
AGP, making sure it's resumed back in the same state it was when suspended.
This is platform specific for now. It would be too complicated to try to
do a generic implementation of this at this point due to all sort of weird
things going on with AGP on other architectures. We'll re-work that whole
problem cleanly once we finally merge fbdev's and DRI.
In the meantime, please apply this patch which brings back some r128 based
laptops into working condition as far as system sleep is concerned.

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!
