Fix error handling in MR allocation for mem-free mode: mthca_free must get an
MR index, not a key.

Roland Dreier 85665c9816 [PATCH] IB/mthca: allocate correct number of doorbell pages
Doorbell record pages are allocated in HCA page size chunks (always 4096
bytes), so we need to divide by 4096 and not PAGE_SIZE when figuring out how
many pages we'll need space for.

Roland Dreier e464b2a6c2 [PATCH] IB/mthca: clean up mthca_dereg_mr()
It's cleaner to kfree mthca_mr, and not rely on the fact that ib_mr is the
first field in mthca_mr.

Roland Dreier e6ded99cbb [PATCH] IPoIB: fix static rate calculation
Correct and simplify calculation of static rate.  We need to round up the
quotient of (local_rate - path_rate) / path_rate.  To round up we add
(path_rate - 1) to the numerator, so the quotient simplifies to (local_rate -
1) / path_rate.

No idea how I came up with the old formula.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
