staging:iio:core add in kernel interface mapping and getting IIO channels.
Lifted from proposal for in kernel interface built on the out of staging
branch.
Two elements here:
* Map as defined in "inkern.h"
* Matching code to actually get the iio_dev and channel
that we want from the global list of IIO devices.
V4: Everything now built if iio is built (rather than being optional)
Removal race condition prevented by using info pointer as a check
of removal under a lock.
V3: Drop the option of registering / getting channels using dev pointer.
Stick to name only as suggested by Mark Brown (this has caused user
confusion in the regulator framework.)
V2: As per Greg KH suggestion, move over to registration by passing
the tables into the provider drivers (how regulator does it).
This does not prevent us using the original more flexible approach
if at a later date there is a usecase that demands it.

staging:iio:core set the iio_dev.info pointer to null on unregister under lock.
This prevents use of provider callbacks after it has been unregistered.
Note that all code using this that can be called from a consumer *must*
check the pointer before using and hold the info_exist_lock throughout
the usage of the callbacks in info.
In order to detect it at runtime, we need the code handling wdt
clock available at runtime to decide whether to enable or disable
based on the baseimage symbols. Default timeout has been set to 5
seconds.
Downside is that we will lose the option to set a custom timeout
for overflow, but than can be added (if needed) as part of debugfs.

In tmem.[ch], new "repatriate" (provoke async get) and "localify" (handle
incoming data resulting from an async get) routines combine with a handful
of changes to existing pamops interfaces allow the generic tmem code
to support asynchronous operations. Also, a new tmem_xhandle struct
groups together key information that must be passed to remote tmem stores.
Zcache-main.c is augmented with a large amount of ramster-specific code
to handle remote operations and "foreign" pages on both ends of the
"remotify" protocol. New "foreign" pools are auto-created on demand.
A "selfshrinker" thread periodically repatriates remote persistent pages
when local memory conditions allow. For certain operations, a queue is
necessary to guarantee strict ordering as out-of-order puts/flushes can
cause strange race conditions. Pampd pointers now either point to local
memory OR describe a remote page; to allow the same 64-bits to describe
either, the LSB is used to differentiate. Some acrobatics must be performed
to ensure local memory is available to handle a remote persistent get,
or deal with the data directly anyway if the malloc failed. Lots
of ramster-specific statistics are available via sysfs.

we can remove duplicated stuff later on.
In order to include the initdef.h we have to rename the header guards.

Staging tree patches for 3.3-rc3
Big things here is the deletion of the Android pmem driver, as it's
obsolete and no one uses it, the gma500 driver as it's already in the
drm portion of the kernel tree, and the pohmelfs filesystem as it's
obsolete and a rewritten version is being proposed for the fs/ section
of the kernel.
Other than that, a smattering of different bugfixes and regressions, and
some omap drm api merge fixups that were needed due to api changes in
the main portion of the drm tree, allowing this code to build properly
again.

staging: zcache: fix serialization bug in zv stats
In a multithreaded workload, the zv_curr_dist_counts
and zv_cumul_dist_counts statistics are being corrupted
because the increments and decrements in zv_create
and zv_free are not atomic.
This patch converts these statistics and their corresponding
increments/decrements/reads to atomic operations.

Reduce the number of expensive division instructions done by _parse_integer()
_parse_integer() does one or two division instructions (which are slow)
per digit parsed to perform the overflow check.
Furthermore, these are particularly expensive examples of division
instruction as the number of clock cycles required to complete them may
go up with the position of the most significant set bit in the dividend:
if (*res > div_u64(ULLONG_MAX - val, base))
which is as maximal as possible.
Worse, on 32-bit arches, more than one of these division instructions
may be required per digit.
So, assuming we don't support a base of more than 16, skip the check if the
top nibble of the result is not set at this point.

[ Changed it to not dereference the pointer all the time - even if the
compiler can and does optimize it away, the code just looks cleaner.
And edited the top nybble test slightly to make the code generated on
x86-64 better in the loop - test against a hoisted constant instead of
shifting and testing the result ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

staging:iio:adc:adt7310/7410 sticking plaster fix for broken event attrs.
Neither of these drivers has ever been anywhere near the iio abi.
Probably as a result of this the fact they had two event groups
each was not picked up when we restricted IIO to having only
1 event line per device (as part of the chrdev merge set).
As such these definitely didn't work before. This patch squishes
the only element from the 'comparator' event line that isn't in the
'interrupt' one into it and kills off the 'comparator' one.
Ultimately both of these drivers belong in hwmon not IIO and are just
waiting here because I don't want to kill off a driver that may
prove useful to someone. (Ultimately I will ask Greg to scrap
these two if no one steps up to deal with them.)
