This patch adds an additional field to the mm_owner callbacks. This field
is required to get to the mm that changed. Hold mmap_sem in write mode
before calling the mm_owner_changed callback

A series of patches introduce a generic header file for the software
IO/TLB implementation in lib/swiotlb.c.  Currently each architecture using
this code defines the prototypes itself.  The prototypes are moved to
include/linux/swiotlb.h and this file is included in architecture specific
code for X86 and IA64.

This patch:

Create include/linux/swiotlb.h file which contains all function prototypes
for the lib/swiotlb.c file.

(akpm: the dependent patches will be trickled through arch trees)

Commit 8006479c introduced a spinlock in
input_dev->event_lock, which is locked when handling input events.
However, the hid-pidff driver sleeps when handling events as it waits for
reports being sent to the device before changing the report contents
again.
This causes a system lockup when trying to use force feedback with a PID
device, a regression introduced in 2.6.24 and 2.6.23.15.

Fix it by extracting the raw report data from struct hid_report
immediately when hid_submit_report() is called, therefore allowing
drivers to change the contents of struct hid_report immediately without
affecting the already-queued transfer.

In hid-pidff, re-add the removed usbhid_wait_io() to
pidff_erase_effect() instead, to prevent a full report queue from causing
the submission to fail, thus not freeing up device memory.
pidff_erase_effect() is not called while dev->event_lock is held.

Make a bus from hid core. This is the first step for converting all the

It's implemented to change behaviour in very tiny manner, so that no driver
needs to be changed this time.

Also add generic drivers for both usb and bt into usbhid or hidp
respectively which will bind all non-blacklisted device. Those blacklisted
will be either grabbed by special drivers or by nobody if they are broken at

The WM8350 has an interrupt line to the CPU which is shared by the
devices on the CPU. This patch adds support for the interrupt
controller within the WM8350 which identifies which identifies the
interrupt cause. In common with other similar chips this is done
outside the standard interrupt framework due to the need to access
the interrupt controller over an interrupt-driven bus.

This code was all originally written by Liam Girdwood with updates for
submission by me.

Some functions of the WM8350 require board-specific initialisation on
startup. Provide a callback to the WM8350 driver in platform data
for platforms to use to configure the chip.  Use of a callback allows
platforms to control the ordering of initialisation which can be
important.

The WM8350 provides a number of user-configurable pins providing access
to various signals generated by the functions on the chip. These are
referred to as GPIO pins in the device documentation but in Linux terms
they are more general than that, providing configuration of alternate
functions.

This patch implements support for selecting the alternate functions for
these pins. They can also be used as GPIOs in the normal Linux sense -
a subsequent patch will add support for doing so.

This code was all written by Liam Girdwood and has had minor updates
and rearrangements by Mark Brown.
