A couple of changes to the Tegra maintainership setup:
I'm very glad to bring on Stephen Warren on board as a maintainer. The
work he has done so far is excellent, and the fact that he works for
Nvidia means he has long-term interest in the platform.
Erik Gilling did an astounding amount of work on getting things up and
running but has been a silent partner on the maintainership side for a
while, and is stepping down. Thanks for your contributions so far, Erik.
Finally, update the git URL since I'll take over running the main repo
for a while.
Overall maintainership model isn't changing much at this time: We'll all
three review patches as appropriate, and one of us will collect the main
repo (me at this time).

Rather than open coding a binary search use the standard bsearch() using
the comparison function we're already using for sort() on insert. This
fixes a lockup I was observing due to iterating on min <= max rather
than min < max when we fail to look up.

We shouldn't change the event flags of input devices after they get registered.
Otherwise, udev will not get notified of these flags and cannot setup the
devices properly.
This fixes the probing to set the input event flags on the input_mapped callback
instead of the probe function.

This patch cleans up several issues with VLANs on igb after the recent
changes that were meant to leave the VLANs enabled/disable via the
netdev->features flags.
Specifically the Rx VLAN settings were being dropped after reset due to the
fact that they were not being restored correctly. In addition I removed
the IRQ disable/enable since those were in place to protect the setting of
vlgrp.

This change is meant to cleanup some of the IVAR register configuration.
igb_assign_vector had become pretty large with multiple copies of the same
general code for setting the IVAR. This change consolidates most of that
code by adding the igb_write_ivar function which allows us just to compute
the index and offset and then use that information to setup the IVAR.

There are a number of places where we have values that are stored as u16

Instead of storing most of the data for the TX hot path in the stack until
we are ready to write the descriptor we can save ourselves some time and
effort by pushing the SKB, tx_flags, gso_size, bytecount, and protocol into
the first igb_tx_buffer since that is where we will end up putting it
anyway.

The LEON MMU Model (SRMMU) does not implement MMu Table probing
in hardware, instead it is implemented in software. However the
software implementation does not return the PTE as it should which
always results in INVALID entires and the PROM mappings are not

This change converts two tx_buffer_info index values into pointers. The
advantage to this is that we reduce unnecessary computations and in the case

having any meaning for the index value.

This patch is meant to simplify the transmit path by reducing the overhead
for creating a transmit context descriptor. The current implementation is
split with igb_tso and igb_tx_csum doing two separate implementations on
how to setup the tx_buffer_info structure and the tx_desc. By combining
them it is possible to reduce code and simplify things since now only one
function will create context descriptors.

In order to be able to improve the performance of the TX path it has been
necessary to add addition info to the tx_buffer_info structure. However a
side effect is that the structure has gotten larger and this in turn has
also increased the size of the RX buffer info structure. In order to avoid
this in the future I am splitting the single buffer_info structure into two
separate ones and instead I will join them by making the buffer_info
pointer in the ring a union of the two.

When short packets are received with jumbos enabled on 82579, they can be
interpreted to have a receive address that does not match any configured
address. This is due to a hardware bug that can be worked around by
reducing the number of IPG octets added when the packet is transferred from
the PHY to the MAC.
