Add support for MR pages larger than 4K on eHCA2. This reduces
firmware memory consumption.  If enabled via the mr_largepage module
parameter, the MR page size will be determined based on the MR length
and the hardware capabilities -- if the MR is >= 16M, 16M pages are
used, for example.

The error handling code at err_wrid in create_qp_common() does not
handle a userspace QP attached to an SRQ correctly, since it ends up
in the else clause of the if statement.  This means it tries to
kfree() the uninitialized qp->sq.wrid and qp->rq.wrid pointers.  Fix
this so we only free the wrid arrays for kernel QPs.

The FW command token is currently only updated on a command completion
event. This means that on command timeout, the same token will be
reused for new command, which results in a mess if the timed out
command *does* eventually complete.

This is the same change as the patch for mthca from Michael
S. Tsirkin <mst@dev.mellanox.co.il> that was just merged.  It seems
sensible to avoid gratuitous differences in FW command processing
between mthca and mlx4.

The ipath_layer.[ch] code was an attempt to provide a single interface
for the ipath verbs and ipath_ether code to use.  As verbs
functionality increased, the layer's functionality became insufficient
and the verbs code broke away to interface directly to the driver.
The failed attempt to get ipath_ether upstream was the final nail in
the coffin and now it sits quietly in a dark kernel.org corner waiting
for someone to notice the smell and send it along to it's final
resting place.  Roland Dreier was that someone -- this patch expands
on his work...

The current scheme works on static interpretation of text names, which
is wrong.

The output-device setting, for example, must be resolved via an alias
or similar to a full path name to the console device.

Paths also contain an optional set of 'options', which starts with a
colon at the end of the path.  The option area is used to specify
which of two serial ports ('a' or 'b') the path refers to when a
device node drives multiple ports.  'a' is assumed if the option
specification is missing.

This was caught by the UltraSPARC-T1 simulator.  The 'output-device'
property was set to 'ttya' and we didn't pick upon the fact that this
is an OBP alias set to '/virtual-devices/console'.  Instead we saw it
as the first serial console device, instead of the hypervisor console.

The infrastructure is now there to take advantage of this to resolve
the console correctly even in multi-head situations in fbcon too.

We ignore all the generated files called "vmlinux*" from the top-level
gitignore, but that also ends up catching a few files that we track, and
that people do edit.  Notably the "vmlinux.lds.S" file, that each
architecture has.

You can always use "git add -f" to override the ignore file, but we
might as well just make it explicit for this file.

The VBI DMA is handled in a special way and is marked with a bit.
However, that bit was set at the wrong time and could be cleared
by mistake if a PCM (or other) DMA request would arrive before the
VBI DMA was completed. So on completion of the VBI DMA the driver
no longer knew that that DMA transfer was for VBI data. And this
in turn caused havoc with the card's DMA engine.
