2017-08-22IB/hfi1: Enable RDMA_CAP_OPA_AH in hfi driver to support extended LIDsDasaratharaman Chandramouli
Enabling this bit helps core components query for extended address support using the rdma_cap_opa_ah interface.

2017-08-22IB/hfi1: Enhance PIO/SDMA send for 16BDon Hiatt
PIO/SDMA send logic now uses the hdr_type field to determine the type of packet that has been constructed. Based on the hdr_type, certain things such as PBC flags, padding count and the LT extra trailing bytes are determined.

2017-08-22IB/hf1: User context locking is inconsistentMichael J. Ruhl
There is a mixture of mutex and spinlocks to protect receive context (rcd/uctxt) information. This is not used consistently. Use the mutex to protect device receive context information only. Use the spinlock to protect sub context information only. Protect access to items in the rcd array with a spinlock and reference count. Remove spinlock around dd->rcd array cleanup. Since interrupts are disabled and cleaned up before this point, this lock is not useful.

2017-08-22IB/hfi1: Use host_link_state to read state when DC is shut downBartlomiej Dudek
When DC is shut down (by e.g. disconnecting the cable), the driver should use host_link_state to get port's current physical state. This is due to the fact that physical state is read from DC's CSRs and when DC is shut down and state is changed, its registers are not impacted.

2017-08-22drm: Release driver tracking before making the object available againChris Wilson
This is the same bug as we fixed in commit f6cd7daecff5 ("drm: Release driver references to handle before making it available again"), but now the exposure is via the PRIME lookup tables. If we remove the object/handle from the PRIME lut, then a new request for the same object/fd will generate a new handle, thus for a short window that object is known to userspace by two different handles. Fix this by releasing the driver tracking before PRIME.
