2015-02-04net/mlx4_core: Fix mpt_entry initialization in mlx4_mr_rereg_mem_write()Maor Gottlieb
a) Previously, mlx4_mr_rereg_write filled the MPT's start and length with the old MPT's values. Fixing the initialization to take the new start and length. b) In addition access flags in mpt_status were initialized instead of status due to bad boolean operation. Fixing the operation. c) Initialization of pd_slave caused a protection error. Fix - removing this initialization. d) In resource_tracker.c: Fixing vf encoding to be one-based.

2015-02-04IB/mlx4: Load balance ports in port aggregation modeMoni Shoua
When the mlx4 IB (RoCE) device works in link aggregation mode, it exposes a single port to upper layers. Therefore, applications always set '1' in port_num attribute when modifying a QP or creating an address handle. To make sure that a node uses all available ports the mlx4 driver will override the port_num attribute with a round robin policy.

2015-02-04net/mlx4_core: Port aggregation upper layer interfaceMoni Shoua
Supply interface functions to bond and unbond ports of a mlx4 internal interfaces. Example for such an interface is the one registered by the mlx4 IB driver under RoCE. There are 1. Functions to go in/out to/from bonded mode 2. Function to remap virtual ports to physical ports The bond_mutex prevents simultaneous access to data that keep status of the device in bonded mode. The upper mlx4 interface marks to the mlx4 core module that they want to be subject for such bonding by setting the MLX4_INTFF_BONDING flag. Interface which goes to/from bonded mode is re-created. The mlx4 Ethernet driver does not set this flag when registering the interface, the IB driver does.

2015-02-04regmap: Fix i2c word access when using SMBus access functionsGuenter Roeck
SMBus access functions assume that 16-bit values are formatted as little endian numbers. The direct i2c access functions in regmap, however, assume that 16-bit values are formatted as big endian numbers. As a result, the current code returns different values if an i2c chip's 16-bit registers are accessed through i2c access functions vs. SMBus access functions. Use regmap_smbus_read_word_swapped and regmap_smbus_write_word_swapped for 16-bit SMBus accesses if a chip is configured as REGMAP_ENDIAN_BIG. If the chip is configured as REGMAP_ENDIAN_LITTLE, keep using regmap_smbus_write_word_data and regmap_smbus_read_word_data. Otherwise reject registration if the controller does not support direct i2c accesses. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Mark Brown <broonie@kernel.org>

It calculates data_direction + exp_data_len for the new tcm_vhost_cmd descriptor by walking both outgoing + incoming iovecs using iov_iter, assuming the layout of outgoing request header + T10_PI + Data payload comes first. It also uses copy_from_iter() to copy leading virtio-scsi request header that may or may not include SCSI CDB, that returns a re-calculated iovec to start of T10_PI or Data SGL memory.

2015-02-04iser-target: Use WQ_UNBOUND for completion workqueueSagi Grimberg
Bound workqueues might be too restrictive since they allow only a single core per session for processing completions. WQ_UNBOUND will allow bouncing to another CPU if the running CPU is currently busy. Luckily, our workqueues are NUMA aware and will first try to bounce within the same NUMA socket. My measurements with NULL backend devices show that there is no (noticeable) additional latency as a result of the change. I'd expect even to gain performance when working with fast devices that also allocate MSIX interrupt vectors. While we're at it, make it WQ_HIGHPRI since processing completions is really a high priority for performance.

When founding a component that has orphan connections, we should validate if it match the newly added device. If it does not match, only then should the @still_orphan flag should be set. The tested result as follows. pre: /sys/bus/coresight/devices # echo 1 > e3c42000.etb/enable_sink /sys/bus/coresight/devices # echo 1 > e3c7c000.ptm/enable_source [ 15.527692] Unable to handle kernel NULL pointer dereference at virtual address 00000124 [ 15.555142] pgd = c2294000 [ 15.564226] [00000124] *pgd=3d393831, *pte=00000000, *ppte=00000000 [ 15.585391] Internal error: Oops: 817 [#1] PREEMPT SMP ARM [ 15.603807] CPU: 0 PID: 144 Comm: sh Not tainted 3.17.0-rc1-12634-g1222fe0-dirty #3 [ 15.629490] task: ed3803c0 ti: c213a000 task.ti: c213a000 [ 15.647627] PC is at coresight_build_paths+0x1c/0x314 [ 15.664579] LR is at coresight_build_paths+0x6c/0x314 [ 15.681526] pc : [<c02da20c>] lr : [<c02da25c>] psr: 20000013 [ 15.681526] sp : c213be88 ip : c02da800 fp : 00000000 [ 15.720023] r10: 00000002 r9 : ed13250c r8 : 00000001 [ 15.737549] r7 : c213bee8 r6 : ffffffea r5 : 00000000 r4 : 00000124 [ 15.759446] r3 : ed216f24 r2 : 00000001 r1 : c213bee8 r0 : 00000000 [ 15.781346] Flags: nzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user post: /sys/bus/coresight/devices # echo 1 > e3c42000.etb/enable_sink /sys/bus/coresight/devices # echo 1 > e3c7c000.ptm/enable_source [ 59.934255] coresight-etb10 e3c42000.etb: ETB enabled [ 59.951317] coresight-replicator replicator0: REPLICATOR enabled [ 59.971581] coresight-funnel e3c41000.funnel: FUNNEL inport 0 enabled [ 59.993334] coresight-etm3x e3c7c000.ptm: ETM tracing enabled Signed-off-by: Kaixu Xia <xiakaixu@huawei.com> Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-02-04usb: musb: fix device hotplug behind hubBin Liu
The commit 889ad3b "usb: musb: try a race-free wakeup" breaks device hotplug enumeraitonn when the device is connected behind a hub while usb autosuspend is enabled. Adding finish_resume_work into runtime resume callback fixes the issue. Also resume root hub is required to resume the bus from runtime suspend, so move musb_host_resume_root_hub() back to its original location, where handles RESUME interrupt.

2015-02-04usb: dwc2: Fix a bug in reading the endpoint directions from reg.Roshan Pius
According to the DWC2 datasheet, the HWCFG1 register stores the configured endpoint directions for endpoints 0-15 in bit positions 0-31. ========================== Endpoint Direction (EpDir) This 32-bit field uses two bits per endpoint to determine the endpoint direction. Endpoint Bits [31:30]: Endpoint 15 direction Bits [29:28]: Endpoint 14 direction .... Bits [3:2]: Endpoint 1 direction Bits[1:0]: Endpoint 0 direction (always BIDIR) ========================== The DWC2 driver is currently interpreting the contents of the register as directions for endpoints 1-15 which leads to an error in determining the configured endpoint directions in the core because the first 2 bits determine the direction of endpoint 0 and not 1. This is based on testing/next branch in Felipe's git. Signed-off-by: Roshan Pius <rpius@chromium.org> Acked-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
