Mike Marciniszyn b6eac931b9 IB/hfi1: Prevent kernel QP post send hard lockups ... The driver progress routines can call cond_resched() when a timeslice is exhausted and irqs are enabled. If the ULP had been holding a spin lock without disabling irqs and the post send directly called the progress routine, the cond_resched() could yield allowing another thread from the same ULP to deadlock on that same lock. Correct by replacing the current hfi1_do_send() calldown with a unique one for post send and adding an argument to hfi1_do_send() to indicate that the send engine is running in a thread. If the routine is not running in a thread, avoid calling cond_resched().
