2017-06-25staging: ccree: register setkey for none hash macsGilad Ben-Yossef
The original ccree driver was registering a useless setkey method even for non-MAC hash transformations. Somewhere around v4.9 a check was added that failed hash operations if a setkey method was registered but was not called, so during the initial upstream port code was added to only register the setkey method for MAC type hash transform. Unfortunately, the ccree driver also registers non-hash based MAC transforms and the code had a logic error that stopped it registering a setkey callback even for those, thus rendering them useless. This commit fixes the logic mistake, thus correctly registering a setkey method only for MAC transformations, leaving it out for non-MAC ones, whether they are hash based on not.

2017-06-24hwmon: (aspeed-pwm-tacho) reduce fan_tach periodPatrick Venture
Reduce the fan_tach period such that the fan controller uses a shorter period to measure the rpm. The original period of 0x1000 was chosen as a conversative value from the reference implementation. Through experimentation on the quanta-q71l board, I was able to drive the number down which ultimately reduced the time the controller would use to determine the fan_tach. This value was recently tested and accepted downstream on the IBM Zaius board which uses the ast2500. Future work: It may be worthwhile as this is a tunable parameter to the system, to allow overriding it through the device tree. Testing: Tested on an ast2400 sitting on a quanta-q71l and ast2500 on power9. Signed-off-by: Patrick Venture <venture@google.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2017-06-24ARM: cpuidle: Support asymmetric idle definitionDaniel Lezcano
Some hardware have clusters with different idle states. The current code does not support this and fails as it expects all the idle states to be identical. Because of this, the Mediatek mtk8173 had to create the same idle state for a big.Little system and now the Hisilicon 960 is facing the same situation. Solve this by simply assuming the multiple driver will be needed for all the platforms using the ARM generic cpuidle driver which makes sense because of the different topologies we can support with a single kernel for ARM32 or ARM64. Every CPU has its own driver, so every single CPU can specify in the DT the idle states. This simple approach allows to support the future dynamIQ system, current SMP and HMP.

2017-06-24cpufreq: intel_pstate: Remove max/min fractions to limit performanceSrinivas Pandruvada
In the current model the max/min perf limits are a fraction of current user space limits to the allowed max_freq or 100% for global limits. This results in wrong ratio limits calculation because of rounding issues for some user space limits. Initially we tried to solve this issue by issue by having more shift bits to increase precision. Still there are isolated cases where we still have error. This can be avoided by using ratios all together. Since the way we get cpuinfo.max_freq is by multiplying scaling factor to max ratio, we can easily keep the max/min ratios in terms of ratios and not fractions. For example: if the max ratio = 36 cpuinfo.max_freq = 36 * 100000 = 3600000 Suppose user space sets a limit of 1200000, then we can calculate max ratio limit as = 36 * 1200000 / 3600000 = 12 This will be correct for any user limits. The other advantage is that, we don't need to do any calculation in the fast path as ratio limit is already calculated via set_policy() callback.

2017-06-23bnxt_en: Fix netpoll handling.Michael Chan
To handle netpoll properly, the driver must only handle TX packets during NAPI. Handling RX events cause warnings and errors in netpoll mode. The ndo_poll_controller() method should call napi_schedule() directly so that a NAPI weight of zero will be used during netpoll mode. The bnxt_en driver supports 2 ring modes: combined, and separate rx/tx. In separate rx/tx mode, the ndo_poll_controller() method will only process the tx rings. In combined mode, the rx and tx completion entries are mixed in the completion ring and we need to drop the rx entries and recycle the rx buffers. Add a function bnxt_force_rx_discard() to handle this in netpoll mode when we see rx entries in combined ring mode.

2017-06-23net: ena: add support for out of order rx buffers refillNetanel Belgazal
ENA driver post Rx buffers through the Rx submission queue for the ENA device to fill them with receive packets. Each Rx buffer is marked with req_id in the Rx descriptor. Newer ENA devices could consume the posted Rx buffer in out of order, and as result the corresponding Rx completion queue will have Rx completion descriptors with non contiguous req_id(s) In this change the driver holds two rings. The first ring (called free_rx_ids) is a mapping ring. It holds all the unused request ids. The values in this ring are from 0 to ring_size -1. When the driver wants to allocate a new Rx buffer it uses the head of free_rx_ids and uses it's value as the index for rx_buffer_info ring. The req_id is also written to the Rx descriptor Upon Rx completion, The driver took the req_id from the completion descriptor and uses it as index in rx_buffer_info. The req_id is then return to the free_rx_ids ring. This patch also adds statistics to inform when the driver receive out of range or unused req_id. Note: free_rx_ids is only accessible from the napi handler, so no locking is required Signed-off-by: Netanel Belgazal <netanel@amazon.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Respect the XDP_FLAGS_HW_MODE. When it's set install the program on the NIC and skip enabling XDP in the driver. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-23nfp: bpf: release the reference on offloaded programsJakub Kicinski
The xdp_prog member of the adapter's data path structure is used for XDP in driver mode. In case a XDP program is loaded with in HW-only mode, we need to store it somewhere else. Add a new XDP prog pointer in the main structure and use that when we need to know whether any XDP program is loaded, not only a driver mode one. Only release our reference on adapter free instead of immediately after netdev unregister to allow offload to be disabled first.

2017-06-23nfp: bpf: don't offload XDP programs in DRV_MODEJakub Kicinski
DRV_MODE means that user space wants the program to be run in the driver. Do not try to offload. Only offload if no mode flags have been specified. Remember what the mode is when the program is installed and refuse new setup requests if there is already a program loaded in a different mode. This should leave it open for us to implement simultaneous loading of two programs - one in the drv path and another to the NIC later.

2017-06-23nfp: xdp: move driver XDP setup into a separate functionJakub Kicinski
In preparation of XDP offload flags move the driver setup into a function. Otherwise the number of conditions in one function would make it slightly hard to follow. The offload handler may now be called with NULL prog, even if no offload is currently active, but that's fine, offload code can handle that.

2017-06-23staging: wlan-ng: Fix struct definition's and variable typeSuniel Mahesh
le16_to_cpu() accepts argument of type __le16 and cpu_to_le16() returns an argument of type __le16. This patch fixes: (a) the type of the variable that end's up getting return from cpu_to_le16(). (b) the member types of struct hfa384x_host_scan_request_data, struct hfa384x_bytestr32 and struct hfa384x_hscan_result_sub. The following type mismatch warnings reported by sparse have been fixed: warning: incorrect type in assignment (different base types) warning: cast to restricted __le16 Signed-off-by: Suniel Mahesh <sunil.m@techveda.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Remove unnecassary casts in the argument to kfree. Found using Coccinelle.

The previous patch which updated screen resolution was tested under wrong environment. sm750 driver does not support 24bpp. It only supports 8bpp, 16bpp and 32bpp. Lets update the default screen resolution to use 32bpp for a better screen performance.
