FUJITA Tomonori 3a2baff783 IB/mthca: Use the dma state API instead of pci equivalents
The DMA API is preferred; no functional change.

Roland Dreier f3781d2e89 RDMA: Remove subversion $Id tags
They don't get updated by git and so they're worse than useless.

Roland Dreier 5a4e6dccbc IB/mthca: Use IRQ safe locks to protect allocation bitmaps
It is supposed to be OK to call mthca_create_ah() and mthca_destroy_ah()
from any context.  However, for mem-full HCAs, these functions use the
mthca_alloc() and mthca_free() bitmap helpers, and those helpers use
non-IRQ-safe spin_lock() internally.  Lockdep correctly warns that
this could lead to a deadlock.  Fix this by changing mthca_alloc() and
mthca_free() to use spin_lock_irqsave().

Roland Dreier 69e9fbb460 IB/mthca: Clean up mthca array index mask
Define a constant MTHCA_ARRAY_MASK to replace repeated uses of
(PAGE_SIZE / sizeof (void *) - 1) in mthca array code.

Michael S. Tsirkin bf74c7479e IB/mthca: Fix mthca_array_clear() thinko
mthca_array_clear() does not clear the slot if the used count is
positive. This leads to crashes in mthca_qp_event() since that uses
mthca_array_get() to check that the qp is valid.

Discovered by Ali Ayoub.

Roland Dreier 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.

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!
