2016-05-26IB/hfi1: Fix hard lockup due to not using save/restore spin lockMike Marciniszyn1-2/+3
Commit b9b06cb6feda ("IB/hfi1: Fix missing lock/unlock in verbs drain callback") added a spin lock. Unfortunately, the new lock code can be called from a base level interrupt state, and an interrupt that can get stacked will attempt to get the same lock. Fix by using the flag save/restore spin lock variation.

2016-05-26IB/hfi1: Move driver out of stagingDennis Dalessandro1-0/+973
The TODO list for the hfi1 driver was completed during 4.6. In addition other objections raised (which are far beyond what was in the TODO list) have been addressed as well. It is now time to remove the driver from staging and into the drivers/infiniband sub-tree.
