The default setting depends on the selected boot mode. In boot mode 00

Since none of the users now reference the cache directly we can happily
remove the custom cache code and rely on the regmap cache.
For simplicity we don't bother with the register defaults tables but
instead read the defaults from the device - regmap is capable of doing

During Device Tree enablement of the ab8500 and db8500-prcmu drivers,
a decision was made to omit registration through the MFD API and use
Device Tree directly. However, because MFD devices have a different
address space and the ab8500 and db8500 both use I2C to communicate,
this causes issues with address translation during execution of
of_platform_populate(). So the solution is to make the MFD core aware
of Device Tree and have it assign the correct node pointers instead.
To make this work the MFD core also needs to be awere of IRQ domains,
as Device Tree insists on IRQ domain compatibility. So, instead of
providing an irq-base via platform code, in the DT case we simply
look up the IRQ domain and map to the correct virtual IRQ.

Ocfs2 uses kiocb.*private as a flag of unsigned long size. In
commit a11f7e6 ocfs2: serialize unaligned aio, the unaligned
io flag is involved in it to serialize the unaligned aio. As
*private is not initialized in init_sync_kiocb() of do_sync_write(),
this unaligned io flag may be unexpectly set in an aligned dio.
And this will cause OCFS2_I(inode)->ip_unaligned_aio decreased
to -1 in ocfs2_dio_end_io(), thus the following unaligned dio
will hang forever at ocfs2_aiodio_wait() in ocfs2_file_aio_write().

For simplicity some WM5102 specific code is included in the core driver,

Here are a number of small fixes for the drivers/staging tree, as well as iio
and pstore drivers (which came from the staging tree in the 3.5-rc1 merge).
All of these are tiny, but resolve issues that people have been reporting.
There's also a documentation update to reflect what the iio drivers really are
doing, which is good to get straightened out.

On arches that do not support this_cpu_cmpxchg_double() slab_lock is used
to do atomic cmpxchg() on double word which contains page->_count. The
page count can be changed from get_page() or put_page() without taking
slab_lock. That corrupts page counter.
Fix it by moving page->_count out of cmpxchg_double data. So that slub
does no change it while updating slub meta-data in struct page.

HD-audio power-up sequence, fixes for ASoC pxa-ssp compile issues, and
bunch of ASoC codec and trivial fix patches.
