Fix regression in HVR-1800 analog support hue/saturation controls.
The changes made for the cx23888 caused regressions in the analog
support for cx23885/cx23887 based boards (partly due to changes in the
locations of the hue/saturation controls). As a result the wrong
registers were being overwritten.
Add code to use the correct registers if it's a cx23888
Validated with the following boards:
HVR-1800 retail (0070:7801)
HVR-1800 OEM (0070:7809)
HVR-1850 retail (0070:8541)
Thanks to Steven Toth and Hauppauge for loaning me various boards to
regression test with.

The refactoring of the cx25840 driver to support the cx23888 caused breakage
with the existing support for cx23885/cx23887 analog support. Rework the
routines such that the new code is only used for the 888.

Commit 7a6f6c29d264cdd2fe0eb3d923217eed5f0ad134 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

Sometimes it doesn't make any sense for a node to have an address.
In this case device lookup will always be unsuccessful because we
currently assume every node will have a reg property. This patch
changes the semantics so that the resource address and the lookup
address will only be compared if one exists.
Things like AUXDATA() rely on of_dev_lookup to return the lookup
entry of a particular device in order to do things like apply
platform_data to a device. However, this is currently broken for
nodes which do not have a reg property, meaning that platform_data
can not be passed in those cases.

We don't need to open code the divide function, just use div_u64 that
already exists and do the same job. While this is a straightforward
clean up, there is more to that, the real motivation for this.
While building on a cross compiling environment in armel, using gcc
4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5), I was getting the following build
error:
ERROR: "__aeabi_uldivmod" [drivers/mtd/nand/nandsim.ko] undefined!
After investigating with objdump and hand built assembly version
generated with the compiler, I narrowed __aeabi_uldivmod as being
generated from the divide function. When nandsim.c is built with
-fno-inline-functions-called-once, that happens when
CONFIG_DEBUG_SECTION_MISMATCH is enabled, the do_div optimization in
arch/arm/include/asm/div64.h doesn't work as expected with the open
coded divide function: even if the do_div we are using doesn't have a
constant divisor, the compiler still includes the else parts of the
optimized do_div macro, and translates the divisions there to use
__aeabi_uldivmod, instead of only calling __do_div_asm -> __do_div64 and
optimizing/removing everything else out.
So to reproduce, gcc 4.6 plus CONFIG_DEBUG_SECTION_MISMATCH=y and
CONFIG_MTD_NAND_NANDSIM=m should do it, building on armel.
After this change, the compiler does the intended thing even with
-fno-inline-functions-called-once, and optimizes out as expected the
constant handling in the optimized do_div on arm. As this also avoids a
build issue, I'm marking for Stable, as I think is applicable for this
case.

threaded IRQs without a primary handler need to be requested with

IRQF_ONESHOT to input drivers where it is missing. Not modified by
this patch are those drivers where the requested IRQ will always be a

When inbound messages arrive, rpmsg core looks up their associated
endpoint (by destination address) and then invokes their callback.
We've made sure that endpoints will never be de-allocated after they
were found by rpmsg core, but we also need to protect against the
(rare) scenario where the rpmsg driver was just removed, and its
callback function isn't available anymore.
This is achieved by introducing a callback mutex, which must be taken
before the callback is invoked, and, obviously, before it is removed.

When an inbound message arrives, the rpmsg core looks up its
associated endpoint and invokes the registered callback.
If a message arrives while its endpoint is being removed (because
the rpmsg driver was removed, or a recovery of a remote processor
has kicked in) we must ensure atomicity, i.e.:
- Either the ept is removed before it is found
or
- The ept is found but will not be freed until the callback returns
This is achieved by maintaining a per-ept reference count, which,
when drops to zero, will trigger deallocation of the ept.
With this in hand, it is now forbidden to directly deallocate
epts once they have been added to the endpoints idr.

In commit 070ad7e793dc ("floppy: convert to delayed work and
single-thread wq") the 'fd_timeout' timer was converted to a delayed
work. However, the "del_timer(&fd_timeout)" was lost in the process,
and any previous pending timeouts would stay active when we then
re-queued the timeout.
This resulted in the floppy probe sequence having a (stale) 20s timeout
rather than the intended 3s timeout, and thus made booting with the
floppy driver (but no actual floppy controller) take much longer than it
should.
Of course, there's little reason for most people to compile the floppy
driver into the kernel at all, which is why most people never noticed.
Canceling the delayed work where we used to do the del_timer() fixes the
issue, and makes the floppy probing use the proper new timeout instead.
The three second timeout is still very wasteful, but better than the 20s
one.

Pull block bits from Jens Axboe:
"As vacation is coming up, thought I'd better get rid of my pending
changes in my for-linus branch for this iteration. It contains:
- Two patches for mtip32xx. Killing a non-compliant sysfs interface
and moving it to debugfs, where it belongs.
- A few patches from Asias. Two legit bug fixes, and one killing an
interface that is no longer in use.
- A patch from Jan, making the annoying partition ioctl warning a bit
less annoying, by restricting it to !CAP_SYS_RAWIO only.
- Three bug fixes for drbd from Lars Ellenberg.
- A fix for an old regression for umem, it hasn't really worked since
the plugging scheme was changed in 3.0.
- A few fixes from Tejun.
- A splice fix from Eric Dumazet, fixing an issue with pipe
resizing."

A recursive lockdep warning occurs if you call
regulator_set_optimum_mode() on a regulator with a supply because
there is no nesting annotation for the rdev->mutex. To avoid this
warning, get the supply's load before locking the regulator's
mutex to avoid grabbing the same class of lock twice.

The below commit introduced a bug in __clk_set_parent()
which could cause it to *skip* the parent validation
which makes sure the parent passed to the api is a valid
one.
commit 7975059db572eb47f0fb272a62afeae272a4b209
Author: Rajendra Nayak <rnayak@ti.com>
Date: Wed Jun 6 14:41:31 2012 +0530
clk: Allow late cache allocation for clk->parents
This was identified by the following compiler warning..
drivers/clk/clk.c: In function '__clk_set_parent':
drivers/clk/clk.c:1083:5: warning: 'i' may be used uninitialized in this function [-Wuninitialized]
.. as reported by Marc Kleine-Budde.
There were various options discussed on how to fix this, one
being initing 'i' to clk->num_parents, but the below approach
was found to be more appropriate as it also makes the 'parent
validation' code simpler to read.

Currently the gpio _runtime_resume/suspend functions are calling the
get_context_loss_count() platform function if the function is populated for
a gpio bank. This function is used to determine if the gpio bank logic state
needs to be restored due to a power transition. This function will be populated
for all banks, but it should only be called for banks that have the
"loses_context" variable set. It is pointless to call this if loses_context is
false as we know the context will never be lost and will not need restoring.
For all OMAP2+ devices gpio bank-0 is in an always-on power domain and so will
never lose context. We found that the get_context_loss_count() was being called
for bank-0 during the probe and returning 1 instead of 0 indicating that the
context had been lost. This was causing the context restore function to be
called at probe time for this bank and because the context had never been saved,
was restoring an invalid state. This ultimately resulted in a crash [1].
This issue is a regression that was exposed by commit 1b1287032 (gpio/omap: fix
missing check in *_runtime_suspend()).
There are multiple bugs here that need to be addressed ...
1. Why the always-on power domain returns a context loss count of 1? This needs
to be fixed in the power domain code [2]. However, the gpio driver should not
assume the loss count is 0 to begin with.
2. The omap gpio driver should never be calling get_context_loss_count for a
gpio bank in a always-on domain. This is pointless and adds unneccessary
overhead.
3. The OMAP gpio driver assumes that the initial power domain context loss count
will be 0 at the time the gpio driver is probed. However, it could be
possible that this is not the case and an invalid context restore could be
performed during the probe. To avoid this only populate the
get_context_loss_count() function pointer after the initial call to
pm_runtime_get() has occurred. This will ensure that the first
pm_runtime_put() initialised the loss count correctly.
This patch addresses issues 2 and 3 above.

If CONFIG_DM_DEBUG_SPACE_MAPS is enabled and memory is fragmented and a
sufficiently-large metadata device is used in a thin pool then the space
map checker will fail to allocate the memory it requires.
Switch from kmalloc to vmalloc to allow larger virtually contiguous
allocations for the space map checker's internal count arrays.
