Pull staging tree changes from Greg Kroah-Hartman:
"Here is the big staging tree pull request for the 3.5-rc1 merge
window.
Loads of changes here, and we just narrowly added more lines than we
added:
622 files changed, 28356 insertions(+), 26059 deletions(-)
But, good news is that there is a number of subsystems that moved out
of the staging tree, to their respective "real" portions of the
kernel.
Code that moved out was:
- iio core code
- mei driver
- vme core and bridge drivers
There was one broken network driver that moved into staging as a step
before it is removed from the tree (pc300), and there was a few new
drivers added to the tree:
- new iio drivers
- gdm72xx wimax USB driver
- ipack subsystem and 2 drivers
All of the movements around have acks from the various subsystem
maintainers, and all of this has been in the linux-next tree for a
while.

Fixed up various trivial conflicts, along with a non-trivial one found
in -next and pointed out by Olof Johanssen: a clean - but incorrect -
merge of the arch/arm/boot/dts/at91sam9g20.dtsi file. Fix up manually
as per Stephen Rothwell.

pstore/ram: Add ECC support
pstore/ram: Switch to persistent_ram routines
...
This is a first step for adding ECC support for pstore RAM backend: we
will use the persistent_ram routines, kindly provided by Google.
Basically, persistent_ram is a set of helper routines to deal with the
[optionally] ECC-protected persistent ram regions.
A bit of Makefile, Kconfig and header files adjustments were needed
because of the move.

This is a transition patch to keep things bisectable, just moves
some routines under '#ifndef MODULE'. The code inside the #ifndef
will go away soon, but so far we must support pstore and ram_console.
So, we are about to use persistent_ram with pstore, with the ability
to compile persistent_ram routines as modules. Some parts of
persistent_ram uses memblock_reserve() routine, which is should be
only used built-in code, and thus it is not exported.
These persistent_ram bits are only used by Android's ram_console,
which is always built-in.
Without this patch, we won't able to compile persistent_ram as a
module:
ERROR: "memblock_reserve" [fs/pstore/ramoops.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
(As alternative, we could export memblock_reserve, but the thing
is: we won't need it later.)

This includes devices' memory (e.g. framebuffers or memory mapped
EEPROMs on a local bus), as well as the normal RAM that we don't use
for the main memory.
For the normal (but unused) ram we could use kmaps, but this assumes
highmem support, so we don't bother and just use the memory via
ioremap.
As a side effect, the following hack is possible: when used together
with pstore_ram (new ramoops) module, we can limit the normal RAM region
with mem= and then point ramoops to use the rest of the memory, e.g.
mem=128M ramoops.mem_address=0x8000000
Sure, we could just reserve the region with memblock_reserve() early in
the arch/ code, and then register a pstore_ram platform device pointing
to the reserved region. It's still a viable option if platform wants
to do so.
Also, we might want to use IO accessors in case of a real device,
but for now we don't bother (the old ramoops wasn't using it either, so
at least we don't make things worse).

The routine just creates a persistent ram zone at a specified address.
For persistent_ram_init_ringbuffer() we'd need to add a
'struct persistent_ram' to the global list, and associate it with a
device. We don't need all this complexity in pstore_ram, so we introduce
the simple function.

This is a longstanding bug, almost unnoticeable when calling
persistent_ram_write() for small buffers.
But when called for large data buffers, the write routine behaves
incorrectly, as the size may never update: instead of clamping
the size to the maximum buffer size, buffer_size_add_clamp() returns
an error (which is never checked by the write routine, btw).
To fix this, we now use buffer_size_add() that actually clamps the
size to the max value.
Also remove buffer_size_add_clamp(), it is no longer needed.

This changes the log initialization to be dynamic, but still
at boot time. These changes are a predecessor to implementing
runtime allocation and freeing of logs, to make the Android logger
less hard-coded.
Change from a fixed set of static log structures, to allocation
at init time into a list. Return proper error numbers on log
allocation failure.

(Life cycle of timed output device driver)
1) register the device as the timed output
2) enable() ops is called via the sysfs
timeout > 0 : timer is activated and device is turned on
timeout = 0 : timer is cancelled and device is off
3) unregister the timed output device if not used any more
So the registered device should be disabled explicitly when the module is removed.
('disabled' means the timer is stopped and the device is turned off)
Rather than implementing that code in each driver,
just call enable() with timeout = 0 to clean up the driver.

The ALARM_ELAPSED_REALTIME clock domain in Android pointed
to the need for something similar in linux system-wide
(instead of limited to just the alarm interface).
Thus CLOCK_BOOTTIME was introduced into the upstream kernel
in 2.6.39.
This patch attempts to convert the android alarm timer to utilize
the kernel's CLOCK_BOOTTIME clockid for ALARM_ELAPSED_REALTIME,
instead of managing it itself.
