2017-04-13brcmfmac: properly align buffers on certain platforms with 64 bit DMAHeiner Kallweit
Systems with 64 bit DMA at least partially require buffers to be used for DMA to be 8-byte-aligned. One example is Amlogic Meson GX. Switching the MMC/SDIO driver for this platform to SG DMA mode resulted in problems due to unaligned buffers. Fortunately the brcmfmac driver has a global define for the alignment.

2017-04-13perf trace: Add usage of --no-syscalls in man pageRavi Bangoria
perf trace supports --no-syscalls option but it's not listed in the man page. (Though, I see an example using --no-syscalls in EXAMPLES section.) Committer note: The --no-syscalls option tells 'perf trace' not to automagically ask for raw_syscalls:sys_{enter,exit} to then format it in a strace like way. This become more used as 'perf trace' got support for arbitrary events, such as tracepoints, so more and more we use: # perf trace --no-syscalls -e nmi:* 0.000 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 36649 handled: 1) 0.019 nmi:nmi_handler:nmi_cpu_backtrace_handler() delta_ns: 2907 handled: 0) 0.676 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 9401 handled: 1) 0.680 nmi:nmi_handler:nmi_cpu_backtrace_handler() delta_ns: 288 handled: 0) 0.701 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 4977 handled: 1) 0.703 nmi:nmi_handler:nmi_cpu_backtrace_handler() delta_ns: 67 handled: 0) 0.736 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 8549 handled: 1) ^C# Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexis Berlemont <alexis.berlemont@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1492063332-5745-1-git-send-email-ravi.bangoria@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2017-04-13perf stat: Fix bug in handling events in error stateStephane Eranian
(This is a patch has been sitting in the Intel CQM/CMT driver series for a while, despite not depend on it. Sending it now independently since the series is being discarded.) When an event is in error state, read() returns 0 instead of sizeof() buffer. In certain modes, such as interval printing, ignoring the 0 return value may cause bogus count deltas to be computed and thus invalid results printed. This patch fixes this problem by modifying read_counters() to mark the event as not scaled (scaled = -1) to force the printout routine to show <NOT COUNTED>.

2017-04-13hwmon: (lm87) Add OF device ID tableJavier Martinez Canillas
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

2017-04-13wil6210: fix memory access violation in wil_memcpy_from/toio_32Dedy Lansky
In case count is not multiple of 4, there is a read access in wil_memcpy_toio_32() from outside src buffer boundary. In wil_memcpy_fromio_32(), in case count is not multiple of 4, there is a write access to outside dst io memory boundary. Fix these issues with proper handling of the last 1 to 4 copied bytes.

2017-04-13wil6210: fix check for sparrow D0 FW fileHamad Kadmany
Driver fails to load FW for sparrow D0 devices in some cases. Fix this by returning correct value from wil_fw_verify_file_exists when D0 FW file is not detected for any reason.

2017-04-13wil6210: protect against sporadic interrupt during suspend flowMaya Erez
During the suspend flow, wil6210 HW can send sporadic interrupts, while PCIe bus is not operational. To prevent that, keep the interrupts disabled during the suspend flow and re-enable them only after PCIe enablement in resume.

2017-04-13wil6210: fix protection against connections during resetHamad Kadmany
Existing code that ignores connection events during reset flow will never take effect since it locks the same mutex taken by the reset flow. In addition, in case of unsolicited disconnect events ignore those as well since device is about to get reset.

2017-04-13wil6210: support 8KB RX buffersLior David
The 11ad spec requires 11ad devices to be able to receive 8KB packets over the air. Currently this is only possible by loading the driver with mtu_max=7912 but this also forces a smaller block ACK window size which reduces performance for stations which transmit normal sized packets (<2KB). Fix this problem as follows: 1. Add a module parameter rx_large_buf that when set, will allocate 8KB RX buffers regardless of mtu_max setting. 2. When receiving block ACK request agree to any window size not above our maximum, regardless of the mtu_max setting. This means if the other side transmits small packets (2KB) it can still set up block ACK with a large window size, and get better performance.

2017-04-13wil6210: restore power save state after internal FW resetLazar Alexei
The power save profile is set to default state in case of FW reset, regardless of the state before the reset took place. Fix this by saving the current power save profile and restore it in case of FW reset.
