2012-01-04of/address: Add reg-names property to name an iomem resourceBenoit Cousson
Add a reg-names property to allow for reg regions to be reference by name instead of by index. Some devices have multiple register regions which are more naturally referenced by name.

2012-01-03IB/mlx4: Fix SL to 802.1Q priority-bits mapping for IBoEOr Gerlitz
For IBoE, SLs 0-7 are mapped to Ethernet 802.1Q user priority bits (pbits) which are part of the VLAN tag, SLs 8-15 are reserved. Under Ethernet, the ConnectX firmware treats (decode/encode) the four bit SL field in various constructs such as QPC / UD WQE / CQE as PPP0 and not as 0PPP. This correlates well to the fact that within the vlan tag the pbits are located in bits 15-13 and not 12-14. The current code wasn't consistent around that area - the encoding was correct for the IBoE QPC.path.schedule_queue field, but was wrong for IBoE CQEs and when MLX header was built. These inconsistencies resulted in wrong SL <--> wire 802.1Q pbits mapping, which is fixed by using SL <--> PPP0 all around the place.

2012-01-03IB/qib: Default some module parameters optimallyMike Marciniszyn
Minimize the need for users to have to set module parameters to get good performance. The following two parameters are changed: - rcvhdrcnt to twice the rcvegrcnt - pcie_caps=0x51 The rcvhdrcnt at twice the egrcount allows the preemptive NAK code during reception to function in 100% of the cases rather than a sender jiffies-based timeout. The pcie_caps default of 0x51 will set the proposed MaxPayload and MaxReceiveReqest to 256 and 4096 respectively. The capabilities on the root complex will be used to limit those values.

2012-01-03IB/qib: Optimize locking for get_txreq()Mike Marciniszyn
The current code locks the QP s_lock, followed by the pending_lock, I guess to to protect against the allocate failing. This patch only locks the pending_lock, assuming that the empty case is an exeception, in which case the pending_lock is dropped, and the original code is executed. This will save a lock of s_lock in the normal case. The observation is that the sdma descriptors will deplete at twice the rate of txreq's, so this should be rare.

2012-01-03IB/uverbs: Protect QP multicast listEli Cohen
Userspace verbs multicast attach/detach operations on a QP are done while holding the rwsem of the QP for reading. That's not sufficient since a reader lock allows more than one reader to acquire the lock. However, multicast attach/detach does list manipulation that can corrupt the list if multiple threads run in parallel. Fix this by acquiring the rwsem as a writer to serialize attach/detach operations. Add idr_write_qp() and put_qp_write() to encapsulate this. This fixes oops seen when running applications that perform multicast joins/leaves.

2012-01-04power_supply: Add initial Charger-Manager driverDonggeun Kim
Because battery health monitoring should be done even when suspended, it needs to wake up and suspend periodically. Thus, userspace battery monitoring may incur too much overhead; every device and task is woken up periodically. Charger Manager uses suspend-again to provide in-suspend monitoring. This patch allows to monitor battery health in-suspend state.
