This patch contains a fix that implements proper communication with the

The MMCI driver might end up aborting the initial command and leaving

problem by ensuring that any data sequence is properly cleared out

According to the Tavor and Arbel programmer's reference manuals, the
number of bytes transferred is not provided in the byte_cnt field of
the CQ entry for atomic operation completions. For atomic operations,
the number of bytes transferred is always 8 (when the status is
"success"), and this constant value should always be used by the
driver in the ib_wc entry returned, rather than using the CQE.

There's a problem with how rdma cm events are reported to userspace
that can lead to application crashes.
When a new connection request arrives, a context for the connection is
allocated in the kernel. The connection event is then reported to
userspace. The userspace library retrieves the event and allocates
its own context for the connection. The userspace context is
associated with the kernel's context when accepting. This allows the
kernel to give userspace context with other events.
A problem occurs if a second event for the same connection occurs
before the user has had a chance to call accept. The userspace
context has not yet been set, which causes the librdmacm to crash.
(This has been seen when the app takes too long to call accept,
resulting in the remote side timing out and rejecting the connection)
Fix this by ignoring events for new connections until userspace has
set their context. This can only happen if an error occurs on a new
connection before the user accepts it. This is okay, since the accept
will just fail later.

On ia64, the various functions that make up cn_proc.c cause kernel
unaligned access errors.
If you are using these, for example, to get notification about all tasks
forking and exiting, you get multiple unaligned access errors per process.
Use put_unaligned() in the appropriate palces to fix this.

The HPT37x driver very carefully handles DMA completions and the needed
fixups are done on pci registers 0x50 and 0x52. This is unfortunate
because the actual registers are 0x50 and 0x54. Fixing this offset cures
the second channel problems reported.
Secondly there are some problems with the HPT370 and certain ATA drives.
The filter code however only filters ATAPI devices due to a reversed type
check.

If we reduce permissions on a pte, we must flush the cached copy of the pte
from the guest's tlb.
This is implemented at the moment by flushing the entire guest tlb, and can be
improved by flushing just the relevant virtual address, if it is known.

The mmu sometimes needs memory for reverse mapping and parent pte chains.
however, we can't allocate from within the mmu because of the atomic context.
So, move the allocations to a central place that can be executed before the
main mmu machinery, where we can bail out on failure before any damage is
done.
(error handling is deffered for now, but the basic structure is there)
