de25968cc8 [PATCH] fix more missing includes
Include fixes for 2.6.14-git11.  Should allow to remove sched.h from
module.h on i386, x86_64, arm, ia64, ppc, ppc64, and s390.  Probably more
to come since I haven't yet checked the other archs.

f8cfa618dc [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback
Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

        int (*suspend)          (struct pcmcia_device *dev);
        int (*resume)           (struct pcmcia_device *dev);

9ad3d6ccf5 [PATCH] USB: Remove USB private semaphore
This patch (as605) removes the private udev->serialize semaphore,
relying instead on the locking provided by the embedded struct device's
semaphore.  The changes are confined to the core, except that the
usb_trylock_device routine now uses the return convention of
down_trylock rather than down_read_trylock (they return opposite values
for no good reason).

A couple of other associated changes are included as well:

	Now that we aren't concerned about HCDs that avoid using the
	hcd glue layer, usb_disconnect no longer needs to acquire the
	usb_bus_lock -- that can be done by usb_remove_hcd where it
	belongs.

	Devices aren't locked over the same scope of code in
	usb_new_device and hub_port_connect_change as they used to be.
	This shouldn't cause any trouble.

Along with the preceding driver core patch, this needs a lot of testing.

baefbc39d8 [PATCH] USB: wakeup flag updates (2/3) uhci-hcd
This makes UHCI stop using the HCD glue wakeup flags to report whether
the controller can wake the system.  The existing code was wrong anyway;
having a PCI PM capability doesn't imply it reports PME# is supported.

I skimmed Intel's ICH7 datasheet and that basically says the wakeup
signaling gets routed only through ACPI registers.  (On the other hand,
many VIA chips provide the PCI PM capabilities...)  I think that doing
this correctly with UHCI is going to require the ACPI folk to associate
the /proc/acpi/wakeup identifiers (and wakeup enable/disable flags)
with the relevant /sys/devices/pci*/...  devices.

d97cc2f2e9 [PATCH] USB: ehci fix driver model wakeup flags
On some systems, EHCI seems to be getting IRQs too early during driver
setup ... before the root hub is allocated, in particular, making trouble
for any code chasing down root hub pointers!  In this case, it seems to
be safe to just ignore the root hub setting.  Thanks to Rafael J. Wysocki
for getting this properly tested.

legacy mode; the PCI PM capability would always do the job.)

6912354a89 [PATCH] USB: EHCI: fix conflation of buf == 0 with len == 0
When the ehci-hcd driver prepares a control URB, it tests for a
zero-length data stage by looking at the transfer_dma value instead of
the transfer_buffer_length.  (In fact it does this even for non-control
URBs, which is an additional aspect of the same bug.)

However, under certain circumstances it's possible for transfer_dma to
be 0 while transfer_buffer_length is non-zero.  This can happen when a
freshly allocated page (mapped to address 0 and marked Copy-On-Write,
but never written to) is used as the source buffer for an OUT transfer.
This patch (as598) fixes the problem.

959eea2191 [PATCH] USB: isp116x-hcd: cleanup
The attached patch makes a cleanup of isp116x-hcd. Most of the volume of
the patch comes from 2 sources: moving the code around to get rid of a
few function prototypes and reworking register dumping functions/macros.
Among other things, switched over from using procfs to debugfs.

Cleanup. The following changes were made:

- Rework register dumping code so it can be used for dumping
  to both syslog and debugfs.
- Switch from procfs to debugfs..
- Die gracefully on Unrecoverable Error interrupt.
- Fix memory leak in isp116x_urb_enqueue(), if HC happens to
  die in a narrow time window.
- Fix a 'sparce' warning (unnecessary cast).
- Report Devices Removable for root hub ports by default
  (was Devices Permanently Attached).
- Move bus suspend/resume functions down in code to get rid of
  a few function prototypes.
- A number of one-line cleanups.
- Add an entry to MAINTAINERS.

535488fcf1 [PATCH] USB: isp116x-hcd: support reiniting HC on resume
Until now the isp116x-hcd had no support to reinitialize the HC on

basically the same as the one tested by Ivan Kalatchev, who reported the
problem, on 2.6.13.

8de9840265 [PATCH] USB: Fix USB suspend/resume crasher (#2)
This patch closes the IRQ race and makes various other OHCI & EHCI code
path safer vs. suspend/resume.
I've been able to (finally !) successfully suspend and resume various
Mac models, with or without USB mouse plugged, or plugging while asleep,
or unplugging while asleep etc... all without a crash.

Alan, please verify the UHCI bit I did, I only verified that it builds.
It's very simple so I wouldn't expect any issue there. If you aren't
confident, then just drop the hunks that change uhci-hcd.c

I also made the patch a little bit more "safer" by making sure the store
to the interrupt register that disables interrupts is not posted before
I set the flag and drop the spinlock.

Without this patch, you cannot reliably sleep/wakeup any recent Mac, and
I suspect PCs have some more sneaky issues too (they don't frankly crash
with machine checks because x86 tend to silently swallow PCI errors but
that won't last afaik, at least PCI Express will blow up in those
situations, but the USB code may still misbehave).

188075211c [PATCH] USB: EHCI updates split init/reinit logic for resume
Moving the PCI-specific parts of the EHCI driver into their own file
created a few issues ... notably on resume paths which (like swsusp)
require re-initializing the controller.  This patch:

 - Splits the EHCI startup code into run-once HCD setup code and
   separate "init the hardware" reinit code.  (That reinit code is
   a superset of the "early usb handoff" code.)

 - Then it makes the PCI init code run both, and the resume code only
   run the reinit code.

 - It also removes needless pci wrappers around EHCI start/stop methods.

 - Removes a byteswap issue that would be seen on big-endian hardware.

The HCD glue still doesn't actually provide a good way to do all this
run-one init stuff in one place though.

f03c17fc9a [PATCH] USB: EHCI updates
This fixes some bugs in EHCI suspend/resume that joined us over the past
few releases (as usbcore, PCI, pmcore, and other components evolved):

  - Removes suspend and resume recursion from the EHCI driver, getting
    rid of the USB_SUSPEND special casing.

  - Updates the wakeup mechanism to work again; there's a newish usbcore
    call it needs to use.

  - Provide simpler tests for "do we need to restart from scratch", to
    address another case where PCI Vaux was lost.  (In this case it was
    restoring a swsusp snapshot, but there could be others.)

Un-exports a symbol that was temporarily exported.

A notable change from previous version is that this doesn't move
the spinlock init, so there's still a resume/reinit path bug.

462aae65f6 [USB]: Make early handoff a final fixup instead of a header one.
At header fixup time, it is not yet legal to ioremap() PCI
device registers, yet that is what this quirk code needs to
do.

541ab4af11 Don't touch USB controller IO registers when they are disabled
The USB "handoff" code is an early PCI quirk to make sure we own the USB
controller (as opposed to the BIOS/SMM).  But if the controller isn't
even enabled yet, don't try to access it.

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

478a3bab8c [PATCH] USB: Always do usb-handoff
This revised patch (as586b) makes usb-handoff permanently true and no
longer a kernel boot parameter.  It also removes the piix3_usb quirk code;
that was nothing more than an early version of the USB handoff code
(written at a time when Intel's PIIX3 was about the only motherboard with
USB support).  And it adds identifiers for the three PCI USB controller
classes to pci_ids.h.
