With dma based spi transmission, data corruption is observed
occasionally. With dma buffers located right next to msg and
xfer fields, cache lines correctly flushed in preparation for
dma usage may be polluted again when writing to fields in the
same cache line.
Make sure cache fields used with dma do not share cache lines
with fields changed during dma handling. As both fields are part
of a struct that is allocated via kzalloc, thus cache aligned,
moving the fields to the 1st position and insert padding for
alignment does the job.

The corgi touchscreen is now deprecated in favour of the generic ads7846.c
driver. The noise reduction technique used in corgi_ts.c, which is to wait
till vsync before ADC sampling, is also integrated into ads7846 driver now.
Provided that the original driver is not generic and is difficult to maintain,
it will be removed now.

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

The time interval between consecutive interrupts depends on a number of
tunables: first_conversion_delay, acquisition_time, averaging and foremost
the pen_down_acc_interval.
Since the mod_timer() action for the PEN UP event happens in the
spi_async() callback function, latencies incurred by the spi bus drivers
also need to be taken into account.
So all in all, give the PEN UP event a bit more wiggle room and increase
timeout to 100ms.

The AD7873 is almost identical to the ADS7846; the only difference is
related to the Power Management bits PD0 and PD1. This results in a
slightly different PENIRQ enable behavior. For the AD7873, VREF should
be turned off during differential measurements.
So, add the AD7873/43 to the list of driver supported devices, and prevent
VREF usage during differential/ratiometric conversion modes.

S3C24XX touchscreen driver, originally written by Arnaud Patard and
other contributors. The driver has had substantial testing as well as
a number of tidying up passes done by Ben Dooks, as noted:
- added kernel-doc comments to most of the routines
- removed old code from pre adc framework days
- updated device probe code to use platform id list matching
- cleaned up debug, since printk() now has timestamp feature
- ensure code uses dev_() reporting macros where necessary
- remove ABS_PRESSURE reporting, tslib can be fixed
- ensure timer is removed on driver exit
- move to using dev_pmops for power management
