2016-03-11staging/rdma/hfi1: fix panic in send engineMike Marciniszyn
The send engine wasn't correctly handling pre-built packets, and worse, the pointer to a packet state's txreq wasn't initialized correctly. To fix: - all waiters need to save any prebuilt packets (smda waits already did) - the progress routine needs to handle a QPs prebuilt packet and initialize the txreq pointer properly To keep SDMA working, the dma send code needs to see if a packet has been built already. If not the code will build it.

2016-03-11IB/qib: Destroy SMI AH before de-allocating the protection domainHarish Chegondi
If SMI AH is not destroyed before de-allocating the PD, it would result in non-zero PD use count when de-allocating the PD, triggering a WARN_ON() at drivers/infiniband/core/verbs.c:284 ib_dealloc_pd+0x69/0xb0 [ib_core]() when unloading the qib driver on systems with dual-port card. This problem has always been there in qib and was detected only after the commit 7dd78647a2c2 ("IB/core: Make ib_dealloc_pd return void") introduced a WARN_ON in ib_dealloc_pd() that triggers if a PD's use count is non-zero before de-allocating the PD.

To do this the s_next_psn is now maintained on post_send() while post_send() related fields are moved to a new cache line. There is an s_avail maintained for the post_send() to mitigate trading cache lines with the send engine. The lock is released/acquired around releasing the just built packet to the egress mechanism.

2016-03-11staging/rdma/hfi1: Fix bug that could block the process on context exitMitko Haralanov
A race was discovred in the user SDMA code, which could result in an process being stuck in the kernel call indefinitely in certain error conditions. If, during the processing of a user SDMA request, there was an error *and* all outstanding SDMA descriptor had been completed by the time the that error case was handled in the calling function, the state of the packet queue would not get correctly updated resulting in the process subsequently getting stuck, thinking that there are more descriptors to be completed. To handle this scenario, the driver now checks the submitted packet count vs. the completed. If all submitted packets have also been completed, the driver can safely free the request and signal user level. Otherwise, this will be handled by the completion callback.

2016-03-11staging/rdma/hfi1: Improve performance of user SDMAMitko Haralanov
To facilitate locked page counting, the user SDMA routines would maintain a list of io vectors, which were freed in the completion callback and then unpin the associated pages during the next call into the kernel. Since the size of this list was unbounded, doing this was bad for performance because the driver ended up spending too much time freeing the io vectors. This commit changes how the io vector freeing is done by moving the actual page unpinning in the callback and maintaining a count of unpinned pages. This count can then be used during the next call into the kernel to update the mm->pinned_vm variable (since that requires process context and the ability to sleep.)
