Looking to get this fix in 3.11.
This is requested for the 3.10 stable tree as well, it fixes a
bug that presents as a scheduler issue when VPHN is active.
VPHN was enabled in the v3.9 window in commit b7abef0.

Enable the driver to function in a Cooperative Memory Overcommitment (CMO)
environment.
The following changes are made to enable the driver for CMO:
* DMA mapping errors will not result in error messages if entitlement has
been exceeded and res
functions need to change
to indicate failure.
* all other platforms will need updates to iommu functions to match the new
calling semantics; they will return 0 on success. The other platforms
default configs have been built, but no further testing was performed.

Activates larger rx buffer pools when the MTU is changed to a larger
value. This patch de-activates the large rx buffer pools when the MTU
changes to a smaller value.

Define a get_io_entitlement function so that it can function in a
Cooperative Memory Overcommitment (CMO) environment (it returns 0 to
indicate that no IO entitlement is required, as the driver does not
perform DMA operations).
