Revert the fix for the deadlock between uvn_io() and uvn_flush(). This fix (ab)use the vnode lock to serialize access to some fields of the corresponding pages associated with UVM vnode object and this will create new deadlocks with the introduction of a per-uobj lock. ok anton@ |

| message |
Fix the deadlock between uvn_io() and uvn_flush() by restarting the fault. Do not allow a faulting thread to sleep on a contended vnode lock to prevent lock ordering issues with upcoming per-uobj lock. Also reduce the sleep value for VM_PAGER_AGAIN from 1sec to 5nsec to not add visible slowdown when starting a multi-threaded application with threads that fault on the same vnode (chromium, firefox, etc).

Remove code which was needed to support old firmware images from iwx(4). Tested with cc-a0-63 and QuZ-a0-hr-b0-63 firmware by myself. Tested with Qu-c0-hr-b0-63 firmware by Fredrik Engberg. |

| message |
Explicitly stop iwx(4) Rx block ack when roaming between access points. This is similar to a recent fix committed to iwm(4). Unlike iwm(4) we do not need to disable Tx aggregation queues in iwx(4). Attempting to do so would cause fatal firmware errors. Tested by jmc@ and myself. |

| message |
Make our old BSSID available to iwx_newstate_task() when roaming. ic_bss->ni_bssid has already been overwritten once we enter iwx_newstate_task() to perform the state transitions necessary for roaming to our new access point (RUN->AUTH->ASSOC->RUN). We do however use the BSSID in commands sent to firmware. Cache our BSSID in struct iwx_node such that firmware commands keep using the old BSSID while we are still tearing things down. Switch to the new BSSID only once we start back up in iwx_auth(). This should be consistent from the firmware's point of view. Same fix as committed for iwm(4) recently. |

Introduce a dummy uvm_obj_destroy() interface. This function will be used in the near future (by mpi@) to improve the locking for uvm objects. Introducing this function now will me allow me to call it in the appropriate place in the drm code. ok mpi@, jsg@ |

Remove misleading uvm reference counting that isn't actually used. Make sure uvm_obj_init() is only called once. Call uvm_obj_destroy() when we release the GEM object that wraps an uvm object for which we called uvm_obj_init(). ok mpi@, jsg@ |
