a4d61e8480 [PATCH] IB: move include files to include/rdma
Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.

288bdeb4bc [PATCH] IB/mthca: Simplify handling of completions with error
Mem-free HCAs never generate error CQEs that complete multiple WQEs,
so just skip the call to mthca_free_err_wqe() for them rather than
having logic to handle the mem-free case in mthca_free_err_wqe().

87b816706b [PATCH] IB/mthca: Factor out common queue alloc code
Clean up the allocation of memory for queues by factoring out the
common code into mthca_buf_alloc() and mthca_buf_free().  Now CQs and
QPs share the same queue allocation code, which we'll also use for SRQs.

42b1806d5c [IB/mthca]: Fix error CQ entry handling on mem-free HCAs
Fix handling of error CQ entries on mem-free HCAs: the doorbell count
is never valid so we shouldn't look at it.  This fixes problems exposed
by new HCA firmware.

ed878458ee [PATCH] IB/mthca: Align FW command mailboxes to 4K
Future versions of Mellanox HCA firmware will require command mailboxes to be
aligned to 4K.  Support this by using a pci_pool to allocate all mailboxes.
This has the added benefit of shrinking the source and text of mthca.

a03a5a67b2 [PATCH] IB/mthca: Move mthca_is_memfree checks
Make mthca_table_put() and mthca_table_put_range() NOPs if the device is not
mem-free, so that we don't have to have "if (mthca_is_memfree())" tests in the
callers of these functions.  This makes our code more readable and
maintainable, and saves a couple dozen bytes of text in ib_mthca.ko as well.

64dc81fca7 [PATCH] IB/mthca: Use dma_alloc_coherent instead of pci_alloc_consistent
Switch all allocations of coherent memory from pci_alloc_consistent() to
dma_alloc_coherent(), so that we can pass GFP_KERNEL.  This should help when
the system is low on memory.

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!
