A recent patch which added an 'unlocked' version of rxe_alloc introduced a
bug causing kzalloc(..., GFP_KERNEL) to be called while holding a spin
lock. This patch corrects that error.
rxe_alloc_nl() should always be called while holding the pool->pool_lock
so the 2nd argument to kzalloc there should be GFP_ATOMIC.
rxe_alloc() prior to the change only locked the code around checking that
pool->state is RXE_POOL_STATE_VALID to avoid races between working threads
and a thread shutting down the rxe driver. This patch reverts rxe_alloc()
to this behavior so the lock is not held when kzalloc() is called.

Currently, polling a umad device will always works, even if the device was
disassociated. A disassociated device should immediately return EPOLLERR
from poll(). Otherwise userspace is endlessly hung on poll() with no idea
that the device has been removed from the system.

MAD message received by the user has EINVAL error in all flows
including when the device is disassociated. That makes it impossible
for the applications to treat such flow differently.
Change it to return EIO, so the applications will be able to perform
disassociation recovery.

The cited commit disallowed creating any QP which isn't raw ethernet, reg
umr or the special UD qp for testing WC, this proved too strict.
While modify can't be done (no GIDS/GID table for example) just creating a
QP is okay.
This patch partially reverts the bellow mentioned commit and places the
restriction at the modify QP stage and not at the creation. DEVX commands
should be used to manipulate such QPs.

An INI QP doesn't require receive CQ, the creation flow sets the recv counts
to zero:
if (cmd->qp_type == IB_QPT_XRC_INI) {
cmd->max_recv_wr = 0;
cmd->max_recv_sge = 0;
The new IOCTL path also does not set the rcq, so make things the same.

Dma-buf based memory region requires one extra parameter and is processed
quite differently. Adding a separate method allows clean separation from
regular memory regions.

Dma-buf is a standard cross-driver buffer sharing mechanism that can be
used to support peer-to-peer access from RDMA devices.
Device memory exported via dma-buf is associated with a file descriptor.
This is passed to the user space as a property associated with the buffer
allocation. When the buffer is registered as a memory region, the file
descriptor is passed to the RDMA driver along with other parameters.
Implement the common code for importing dma-buf object and mapping dma-buf
pages.
