A lot of ipath layer code was only called in one place. Now that the ipath_core and ib_ipath drivers are merged, it's more sensible to simply inline the simple stuff that the layer code was doing.

Ordering of writethrough store buffers needs to be forced, and we need to use ifdef to get writethrough behavior to InfiniPath buffers, because there is no generic way to specify that at this time (similar to code in char/drm/drm_vm.c and block/z2ram.c).

Improve performance of userspace post receive, post SRQ receive, and poll CQ operations for ipath by allowing userspace to directly mmap() receive queues and completion queues.

The SM LID used to send traps to is incorrectly set to port LID. This is a regression from 2.6.17 -- after a PortInfo MAD is received, no traps are sent to the SM LID. The traps go to the loopback interface instead, and are dropped there. The SM LID should be taken from the sm_lid of the PortInfo response.

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(). Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Leave all SRQ methods out of the device's uverbs_cmd_mask if the device doesn't have SRQ support (because of ancient firmware) so that we don't allow userspace to call the driver's create_srq method. This fixes a userspace-triggerable oops caused by ib_uverbs_create_srq() following the device's ->create_srq function pointer, which will be NULL if the device doesn't support SRQs.

When destroying a QP, mthca locks both the QP's send CQ and receive CQ. However, the following scenario is perfectly valid: QP_a: send_cq == CQ_x, recv_cq == CQ_y QP_b: send_cq == CQ_y, recv_cq == CQ_x The old mthca code simply locked send_cq and then recv_cq, which in this case could lead to an AB-BA deadlock if QP_a and QP_b were destroyed simultaneously. We can fix this by changing the locking code to lock the CQ with the lower CQ number first, which will create a consistent lock ordering. Also, the second CQ is locked with spin_lock_nested() to tell lockdep that we know what we're doing with the lock nesting. This bug was found by lockdep.

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.

ipath_skip_sge() doesn't exactly duplicate the side effects of ipath_copy_sge() if num_sge > 1 since it doesn't decrement ss->num_sge. This could result in the sg_list being accessed out of bounds. Since ipath_skip_sge() is almost always called with num_sge == 1, the original "optimization" is almost never used.

mthca: initialize send and receive queue locks separately lockdep identifies a lock by the call site of its initialization. By initializing the send and receive queue locks in mthca_wq_init() we confuse lockdep. It warns that that the ordered acquiry of both locks in mthca_modify_qp() is recursive acquiry of one lock: ============================================= [ INFO: possible recursive locking detected ] --------------------------------------------- modprobe/1192 is trying to acquire lock: (&wq->lock){....}, at: [<f892b4db>] mthca_modify_qp+0x60/0xa7b [ib_mthca] but task is already holding lock: (&wq->lock){....}, at: [<f892b4ce>] mthca_modify_qp+0x53/0xa7b [ib_mthca] Initializing the locks separately in mthca_alloc_qp_common() stops the warning and will let lockdep enforce proper ordering on paths that acquire both locks.
