Fixing and cleaning up several remoteproc and rpmsg issues.
In addition, remoteproc's resource table is converted to a collection
of type-value members, instead of a rigid array of homogeneous structs.
This enables remoteproc to support registration of generic virtio devices,
and not only a single VIRTIO_ID_RPMSG virtio device.
But perhaps more importantly, the resource table overhaul makes it possible
to easily extend it in the future without breaking older images (simply by
defining a new member type, while continuing to support older types).

When destroying a listening cmid, the iwcm first marks the state of
the cmid as DESTROYING, then releases the lock and calls into the
iWARP provider to destroy the endpoint. Since the cmid is not locked,
its possible for the iWARP provider to pass a connection request event
to the iwcm, which will be silently dropped by the iwcm. This causes
the iWARP provider to never free up the resources from this connection
because the assumption is the iwcm will accept or reject this connection.
The solution is to reject these connection requests.

Further, passing the flag variable from iwch_modify_qp() is just wrong

Tegra PCIe driver waits for PLL to lock using busy loop.
If PLL fails to lock for some reason, this leads to silent lockup
while booting (as PCIe code is not modular).
Fix by adding timeout, so if PLL doesn't lock in a couple
of seconds, just PCIe driver fails and machine continues to boot.

This patch splits the DMM off into a separate sub-device, in order to
utilize the platform device information that was created as part of
the OMAP hwmod entry for the DMM.
The driver probe function queries the iomem resource and IRQ using
standard platform_get functions.
The OMAP DRM driver now calls the platform_driver_register() function
for the subordinate DMM driver inside its probe function. This
guarantees the required order for the DMM and ensures the DMM resources
are available for use by the DRM driver.

tsl2563 probe function has two minor issues with it's error handling paths:
1) it is silent (did not report errors to dmesg)
2) did not return failure code (mixed up use of ret and err)
and two major issues:
3) goto fail2 would corrupt a free memory pool ("double free")
4) device registration failure did NOT cancel/flush delayed work.
(and thus dereference a freed data structure later)
The "double free" is subtle and was introduced with this change:
Author: Jonathan Cameron <jic23@cam.ac.uk>
Date: Mon Apr 18 12:58:55 2011 +0100
staging:iio:tsl2563 take advantage of new iio_device_allocate private data.
Originally, chip was allocated seperately. Now it's appended to the
indio_dev by iio_allocate_device(sizeof(*chip)). So we only need one
kfree call as well (in iio_free_device()).
Gory details of tracking this down are here:
http://crosbug.com/26819
Despite iio_device_registration failing, system can at least now boot.
Will follow up with a fix to "double register : in_intensity_both_raw"
error that is included in the bug report.

The lowmemorykiller registers an atomic notifier for notfication of when
the task is freed. From this atomic notifier callback, it removes the
atomic notifier via task_free_unregister(). This is incorrect because
atomic_notifier_chain_unregister() calls syncronize_rcu(), which can
sleep, which shouldn't be done from an atomic notifier.
Fix this by registering the notifier during init, and only unregister it
if the lowmemorykiller is unloaded.
