Create a separate mode_config IDR lock for simplicity. The core DRM
config structures (connector, mode, etc. lists) are still protected by
the mode_config mutex, but the CRTC IDR (used for the various identifier
IDs) is now protected by the mode_config idr_mutex. Simplifies the
locking a bit and removes a warning.
All objects are protected by the config mutex, we may in the future,
split the object further to have reference counts.

Commit 3ada8b7e ("block: struct device - replace bus_id with dev_name(),
dev_set_name()") deleted the code in register_disk() that changed a '/'
to a '!' in the device name when registering a disk, but dev_set_name()
does not perform this conversion.
This leads to amusing problems with disks that have '/' in their names:
for example a failure to boot with the root partition on a cciss device,
even though the kernel says it knows about the root device:
VFS: Cannot open root device "cciss/c0d0p6" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
6800 71652960 cciss/c0d0 driver: cciss
6802 1 cciss/c0d0p2
6805 2931831 cciss/c0d0p5
6806 34354908 cciss/c0d0p6
6810 71652960 cciss/c0d1 driver: cciss
Fix this by adding code to change '/' to '!' in dev_set_name() to handle
this until dev_set_name() is converted to use kobject_set_name().

i.MX3x SoCs contain an Image Processing Unit, consisting of a Control
Module (CM), Display Interface (DI), Synchronous Display Controller (SDC),
Asynchronous Display Controller (ADC), Image Converter (IC), Post-Filter
(PF), Camera Sensor Interface (CSI), and an Image DMA Controller (IDMAC).
CM contains, among other blocks, an Interrupt Generator (IG) and a Clock
and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are
supported over dmaengine and irq-chip APIs respectively.
IDMAC is a specialised DMA controller, its DMA channels cannot be used for
general-purpose operations, even though it might be possible to configure
a memory-to-memory channel for memcpy operation. This driver will not work
with generic dmaengine clients, clients, wishing to use it must use
respective wrapper structures, they also must specify which channels they
require, as channels are hard-wired to specific IPU functions.

A pointer to wm8400_regulator_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

There is a problem in our handling of suspend-resume of PCI devices that
many of them have their standard config registers restored with
interrupts enabled and they are put into the full power state with
interrupts enabled as well. This may lead to the following scenario:
* an interrupt vector is shared between two or more devices
* one device is resumed earlier and generates an interrupt
* the interrupt handler of another device tries to handle it and
attempts to access the device the config space of which hasn't been
restored yet and/or which still is in a low power state
* the system crashes as a result
To prevent this from happening we should restore the standard
configuration registers of all devices with interrupts disabled and we
should put them into the D0 power state right after that.
Unfortunately, this cannot be done using the existing
pci_set_power_state(), because it can sleep. Also, to do it we have to
make sure that the config spaces of all devices were actually saved
during suspend.

The current work request posting code writes the LSO segment before
writing any data segments. This leaves a window where the LSO segment
overwrites the stamping in one cacheline that the HCA prefetches
before the rest of the cacheline is filled with the correct data
segments. When the HCA processes this work request, a local
protection error may result.
Fix this by saving the LSO header size field off and writing it only
after all data segments are written. This fix is a cleaned-up version
of a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>.
