6cd3209967 powerpc/powermac: New windfarm driver for PowerMac G5 (AGP) and Xserve G5
This replaces the old therm_pm72 using the same windfarm infrastructure
that was used for other PowerMac G5 models. The fan speeds and sensors
should now be visible in the same location in sysfs.

The driver is split into separate core modules for PowerMac7,2 (and 7,3)
and RackMac3,1, with a lot of the shared code now in the separate sensor
and control modules.

d839ba2ab2 powerpc/windfarm: Updates to lm75 and max6690 sensors
This allows those modules to load on PowerMac7,2 PowerMac7,3
and RackMac3,1 and add the sensor name conversion for those
machines.

This will be used by the corresponding new windfarm modules
for those machines.

Note that since therm_pm72 is linked first, it will still
take priority on those i2c devices if built-in. If using modules
it will depend which is loaded first, but you should avoid building
therm_pm72 if you are using the new windfarm drivers

81e5d8646f i2c/powermac: Register i2c devices from device-tree
This causes i2c-powermac to register i2c devices exposed in the
device-tree, enabling new-style probing of devices.

Note that we prefix the IDs with "MAC," in order to prevent the
generic drivers from matching. This is done on purpose as we only
want drivers specifically tested/designed to operate on powermacs
to match.

This removes the special case we had for the AMS driver, and updates
the driver's match table instead.

3a69ddd6f8 drm/i915: Set the Stencil Cache eviction policy to non-LRA mode.
Clearing bit 5 of CACHE_MODE_0 is necessary to prevent GPU hangs in
OpenGL programs such as Google MapsGL, Google Earth, and gzdoom when
using separate stencil buffers.  Without it, the GPU tries to use the
LRA eviction policy, which isn't supported.  This was supposed to be off
by default, but seems to be on for many machines.

This cannot be done in gen6_init_clock_gating with most of the other
workaround bits; the render ring needs to exist.  Otherwise, the
register write gets dropped on the floor (one printk will show it
changed, but a second printk immediately following shows the value
reverts to the old one).

Pull Xen fixes from Konrad Rzeszutek Wilk:
 "Some of these had been in existence since the 2.6.27 days, some since
  3.0 - and some due to new features added in v3.4.

  The one that is most interesting is David's one - in the low-level
  assembler code we had be checking events needlessly.  With his patch
  now we do it when the appropriate flag is set - with the added benefit
  that we can process events faster.  Stefano's is fixing a mistake
  where the Linux IRQ numbers were ACK-ed instead of the Xen IRQ,
  resulting in missing interrupts.  The other ones are bootup related
  that can show up on various hardware."

 - In the low-level assembler code we would jump to check events even if
   none were present.  This incorrect behavior had been there since
   2.6.27 days!
 - When using the fast-path for ACK-ing interrupts we were using the
   Linux IRQ numbers instead of the Xen ones (and they can differ) and
   missing interrupts in process.
 - Fix bootup crashes when ACPI hotplug CPUs were present and they would
   expand past the set number of CPUs we were allocated.
 - Deal with broken BIOSes when uploading C-states to the hypervisor.
 - Disable the cpuid check for MWAIT_LEAF if the ACPI PAD driver is
   loaded.  If the ACPI PAD driver is used it will crash, so lets not
   export the functionality so the ACPI PAD driver won't load.

Pull build fixes for less mainstream architectures from Paul Gortmaker:
 "These are fixes for frv(1), blackfin(2), powerpc(1) and xtensa(4).

  Fortunately the touches are nearly all specific to files just used by
  the arch in question.  The two touches to shared/common files
  [kernel/irq/debug.h and drivers/pci/Makefile] are trivial to assess as
  no risk to anyone.

  Half of them relate to xtensa directly.  It was only when I fixed the
  last xtensa issue that I realized that the arch has been broken for a
  significant time, and isn't a specific v3.4 regression.  So if you
  wanted, we could leave xtensa lying bleeding in the street for a
  couple more weeks and queue those for 3.5.  But given they are no risk
  to anyone outside of xtensa, I figured to just leave them in.

  If you are OK with taking the xtensa fixes, then please pull to get:

   - one last implicit include uncovered by system.h that is in a file
     specific to just one powerpc defconfig.  (I'd sync'd with BenH).

   - fix an oversight in the PCI makefile where shared code wasn't being
     compiled for ARCH=frv

   - fix a missing include for GPIO in blackfin framebuffer.

   - audit and tag endif in blackfin ezkit board file, in order to find
     and fix the misplaced endif masking a block of code.

   - fix irq/debug.h choice of temporary macro names to be more internal
     so they don't conflict with names used by xtensa.

   - fix a reference to an undeclared local var in xtensa's signal.c

   - fix an implicit bug.h usage in xtensa's asm/io.h uncovered by my
     removing bug.h from kernel.h

   - fix xtensa to properly indicate it is using asm-generic/hardirq.h
     in order to resolve the link error - undefined ack_bad_irq

  The xtensa still fails final link as my latest binutils does something
  evil when ld forward-relocates unlikely() blocks, but in theory people
  who have older/valid toolchains could now use the thing."

ea505bc99f spi/pl022: Allow request for higher frequency than maximum possible
Currently, if we request for frequency greater than maximum possible, spi driver
returns error.

For example, if the spi block src frequency is 333/4 MHz, i.e. 83.33.. MHz,
maximum frequency programmable would be src/2. Which would come around 41.6...

It is difficult to pass frequency in these figures. We normally try to program
in round figures, like 42 MHz and it should get programmed to <=
requested_frequency, i.e. 41.6...

For this to happen, we must not return error even if requested freq is higher
than max possible. But should program it to max possible.

cde4384e10 spi/bcm63xx: convert to the pump message infrastructure
This patch converts the bcm63xx SPI driver to use the SPI infrastructure
pump message queue. Since we were previously sleeping in the SPI
driver's transfer() function (which is not allowed) this is now fixed as well.

To complete that conversion a certain number of changes have been made:
- the transfer len is split into multiple hardware transfers in case its
  size is bigger than the hardware FIFO size
- the FIFO refill is no longer done in the interrupt context, which was a
  bad idea leading to quick interrupt handler re-entrancy

d4b9b578cb spi/spi-ep93xx.c: use dma_transfer_direction instead of dma_data_direction
A new enum indicating the dma channel direction was introduced by:

commit 49920bc669
    dmaengine: add new enum dma_transfer_direction

The following commit changed spi-ep93xx to use the new enum:

commit a485df4b44
    spi, serial: move to dma_transfer_direction

In doing so a sparse warning was introduced:

warning: mixing different enum types
   int enum dma_data_direction  versus
   int enum dma_transfer_direction

This is produced because the 'dir' passed in ep93xx_spi_dma_prepare
is an enum dma_data_direction and is being used to set the
dma_slave_config 'direction' which is now an enum dma_transfer_direction.

Fix this by converting spi-ep93xx to use the new enum type in all
places.

usb: fixes for v3.4-rc cycle

A few more fixes for v3.4-rc cycle.

It includes a couple of fixes to the ordering of the methods in udc-core.c.
Without these two patches, we will have issues when either unregistering a
gadget driver (triggered with dummy_hcd only) or issuing a device-initiated
disconnect through sysfs.

There's also a fix on dummy_hcd to not call ->pullup() from udc_stop() because
udc-core.c already handles that.

A fix to MUSB as promised, to kill the compile warnings regarding deprecated
interfaces. We are essentially dropping the __deprecated flag because it
doesn't look like we will ever be able to live without it when we consider the
amount of silicon issues we find on different MUSB instantiations.

A couple of other fixes are also available, one adding the missing transceiver
events to gpio_vbus and another adding a missing unregister call to MUSB's
davinci glue layer.

320cd1e750 usb: gadget: udc-core: fix incompatibility with dummy-hcd
This patch (as1548) fixes a recently-introduced incompatibility
between the UDC core and the dummy-hcd driver.  Commit
8ae8090c82 (usb: gadget: udc-core: fix
asymmetric calls in remove_driver) moved the usb_gadget_udc_stop()
call in usb_gadget_remove_driver() below the usb_gadget_disconnect()
call.

As a result, usb_gadget_disconnect() gets called at a time when the
gadget driver believes it has been unbound but dummy-hcd believes
it has not.  A nasty error ensues when dummy-hcd calls the gadget
driver's disconnect method a second time.

To fix the problem, this patch moves the gadget driver's unbind
notification after the usb_gadget_disconnect() call.  Now nothing
happens between the two unbind notifications, so nothing goes wrong.

From Daniel Vetter

- VGA load-detect fix. This bug seems to be as old as the load-detect code
  (2.6.30), but needs stupid userspace (upowerd trying to detect
  connectors on dpms-off outputs) to actually kill the machine. And
  obviously a machine without VGA-hotplug, otherwise we don't do load
  detect.
- 2 interger overflow fixes for unpriviledged ioctls from Xi Wang.
- Fix SDVO regression for low-res (pixelclock < 100MHz) digital outputs,
 introduce in 2.6.36.

b95ace54a2 ARM: pxa: fix gpio wakeup setting
In 3.3, gpio wakeup setting was broken. The call
enable_irq_wake() didn't set up the PXA gpio registers
(PWER, ...) anymore.

Fix it at least for pxa27x. The driver doesn't seem to be
used in pxa25x (weird ...), and the fix doesn't extend to
pxa3xx and pxa95x (which don't have a gpio_set_wake()
available).
