may not be visible to userspace at all at present and would just have a

That could be easily added (provided the string is not too long).

Not on sane platforms I guess. We would have problems much worse than MC API

To maintain compatibility with drivers that rely on v4l2_device storing
a pointer to itself in the device's drvdata, v4l2_device_register() will
keep doing so if the drvdata is NULL.

If the TRM uses two underscores I'm fine with it.

My understanding is that Linus will remove all ARM defconfigs in 2.6.36,
unless someone can convince him not to. Board-specific defconfigs won't be
allowed anymore, the number of defconfigs needs to be reduced drastically
(ideally to one or two only).

The IOMMU virtual memory mapping API requires page-aligned buffers.
There's no hardware reason behind such a restriction. Remove it by
rounding the address of the first page entry down, and adding the offset
back to the IOMMU virtual address.

If the pipeline is misconfigured, the isp_video_far_end function could
