Due to the default case handling the older chipsets, a bunch of the newer
ones ended up having the wrong tiling regs used. This commit switches the
default case to handle the newest chipsets.
This also makes nv4e touch the "extra" tiling regs. "nv" doesn't touch
them for C51 but traces of the NVIDIA binary driver show it being done
there.
I couldn't find NV41/NV45 traces to confirm the behaviour there, but an
educated guess was taken at each of them.

PCI: SR-IOV quirk for Intel 82576 NIC
If BIOS doesn't allocate resources for the SR-IOV BARs, zero the Flash
BAR and program the SR-IOV BARs to use the old Flash Memory Space.
Please refer to Intel 82576 Gigabit Ethernet Controller Datasheet
section 7.9.2.14.2 for details.

This quirk was added before SR-IOV was in production and now all machines that
originally had this issue alreayd have bios updates to correct the issue. The
quirk itself is no longer needed and in fact causes bugs if run. Remove it.

There are two spellings in use for 'freeze' + 'able' - 'freezable' and
'freezeable'. The former is the more prominent one. The latter is
mostly used by workqueue and in a few other odd places. Unify the
spelling to 'freezable'.

On systems where the temperature sensor is actually used, the BIOS is
likely to have locked the alarm registers. In that case, all writes
through the corresponding sysfs files would be silently ignored.
To prevent this, detect the locks and make the affected sysfs files
read-only.

If the gpu is hung, then whatever was inside the render cache is lost
and there is little point waiting for it. Or complaining if we see an
EIO or EAGAIN instead. So, if the GPU is indeed in its death throes when
we need to rewrite the registers for a new framebuffer, just ignore the
error and proceed with the update.

'mdp' devices are md devices with preallocated device numbers
for partitions. As such it is possible to mknod and open a partition
before opening the whole device.
this causes md_probe() to be called with a device number of a
partition, which in-turn calls mddev_find with such a number.
However mddev_find expects the number of a 'whole device' and
does the wrong thing with partition numbers.
So add code to mddev_find to remove the 'partition' part of
a device number and just work with the 'whole device'.

If the desired size of an array is set (via sysfs) before the array is
active (which is the normal sequence), we currrently call set_capacity
immediately.
This means that a subsequent 'open' (as can be caused by some
udev-triggers program) will notice the new size and try to probe for
partitions. However as the array isn't quite ready yet the read will
fail. Then when the array is read, as the size doesn't change again
we don't try to re-probe.
So when setting array size via sysfs, only call set_capacity if the
array is already active.

Request_region should be used with release_region, not release_resource.
The local variable mem, storing the result of request_mem_region, is
dropped and instead the pointer res is stored in the drvdata field of the
platform device. This information is retrieved in omap_rng_remove to
release the region. The drvdata field is not used elsewhere.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>

(
*x = request_region(...)

Right now the platform device and its platform data is included in one big
struct which requires its custom ->release function. The problem with the
release function within the driver is that it might be called after the
driver was removed because someone was holding a reference to it and it
was not called right after platform_device_unregister(). So we also free
the platform device memory to which one might hold a reference.
This patch uses the normal pdev functions so this kind of race does not
occur.
