[PATCH 0 of 18] [RFC] ipath - almost-final round of patches for submission

["Bryan O'Sullivan" <bos@pathscale.com>]

This is another round of ipath driver patches for review.  I believe
the driver is almost ready for submission.  We have addressed all prior
feedback that I am aware of.

Major changes since the last round of review comments:

  - Layered drivers now do the right thing when the underlying devices
    get hotplugged.

  - The memory leak that Linus, Hugh, and others have been so helpful with
    during the past week is fixed; we now use remap_pfn_range instead of a
    nopage handler.

  - There are no longer any binary or multiple-valued files in sysfs.
    Instead, we've added an ipathfs filesystem for that stuff.

There are two things left to do:

  - ipath_rc.c contains some enormous functions that we are in the
    process of breaking up into more digestible chunks.

  - The ipathfs filesystem doesn't handle hotplugged devices.

If you have any comments or suggestions, please let me know.  If the
current code looks OK, I expect to make a final submission for 2.6.17
in a day or two, once we have the above two items completed.
