For ethernet support, we need to reserve QPs for the ethernet and
fibre channel driver. The QPs are reserved at the end of the QP
table. (This way we assure that they are aligned to their size)
We need to consider these reserved ranges in bitmap creation, so we
extend the mlx4 bitmap utility functions to allow reserved ranges at
both the bottom and the top of the range.

Update existing Mellanox copyright lines to 2008, and add such lines

Commit ee49bd93 ("mlx4_core: Reset device when internal error is
detected") introduced some section mismatch problems when
CONFIG_HOTPLUG=n, because the error recovery code tears down and
reinitializes the device after everything is loaded, which ends up
calling into lots of code marked __devinit and __devexit from regular
.text. Fix this by getting rid of these now-incorrect section
markers.

mlx4_srq_query() returns a big-endian 16-bit value through an int *,
which screws up sparse checking. Fix this so that a CPU-endian value
is returned.

Add an InfiniBand driver for Mellanox ConnectX adapters. Because
these adapters can also be used as ethernet NICs and Fibre Channel
HBAs, the driver is split into two modules:
mlx4_core: Handles low-level things like device initialization and
processing firmware commands. Also controls resource allocation
so that the InfiniBand, ethernet and FC functions can share a
device without stepping on each other.
mlx4_ib: Handles InfiniBand-specific things; plugs into the
InfiniBand midlayer.
