Stephane Chatty 57fd637ad9 HID: Multitouch support for the N-Trig touchscreen
Adds support for multitouch interaction on the N-Trig touchscreen, using the
new ABS_MT_* input constants. Single touch support works as previously. This
code was tested against two versions of the N- Trig firmware: one that supports
dual pen/finger single touch, and one that supports finger multitouch but no
pen at all. Copyright notices that looked wrong were removed, as it seems that
there is only code written in 2009 by Rafin Rubin and Stephane Chatty in this
file.

Stephane Chatty 89f536ccfa HID: add new multitouch and digitizer contants
Added constants to hid.h for all digitizer usages (including the new multitouch
ones that are not yet in the official USB spec but are being pushed by Microsft
as described in their paper "Digitizer Drivers for Windows Touch and Pen-Based
Computers"). Updated hid-debug.c to support the new MT input constants such as
ABS_MT_POSITION_X.

Maciej Sosnowski 4f005dbe55 ioatdma: fix "ioatdma frees DMA memory with wrong function"
as reported by Alexander Beregalov <a.beregalov@gmail.com>

ioatdma 0000:00:08.0: DMA-API: device driver frees DMA memory with
wrong function [device address=0x000000007f76f800] [size=2000 bytes]
[map
ped as single] [unmapped as page]

The ioatdma driver was unmapping all regions
(either allocated as page or single) using unmap_page.
This patch lets dma driver recognize if unmap_single or unmap_page should be used.
It introduces two new dma control flags:
DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE.
They should be set to indicate dma driver to do dma-unmapping as single
(first one for the source, tha latter for the destination).
If respective flag is not set, the driver assumes dma-unmapping as page.

Harald Welte ee1ef82c7e viafb: make it work on x86_64
Fix a bug in viafb on x86_64 builds (e.g. for VIA Nano CPU).

You cannot make the assumption that sizeof(unsigned int) ==
sizeof(unsigned long), so the parsing of the default mode (640x480) fails,
leading to a division by zero during insmod of the driver.

Tejun Heo 9aa7a7d5da alpha: unbreak percpu again
Commit 9b8de7479d ("FRV: Fix the section
attribute on UP DECLARE_PER_CPU()") cleaned up DECLARE/DEFINE_PER_CPU()
macros and in the process made alpha percpu.h include
include/asm-generic/percpu.h which breaks compilation due to duplicate
definitions.

Remove inclusion of generic asm helper file and define whatever necessary
in alpha header proper.

In the longer term, percpu definitions will be unified and all these
little subtlties will be removed.
