2019-03-07net: stmmac: Avoid sometimes uninitialized Clang warningsNathan Chancellor
When building with -Wsometimes-uninitialized, Clang warns: drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:495:3: warning: variable 'ns' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:495:3: warning: variable 'ns' is used uninitialized whenever '&&' condition is false [-Wsometimes-uninitialized] drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:532:3: warning: variable 'ns' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:532:3: warning: variable 'ns' is used uninitialized whenever '&&' condition is false [-Wsometimes-uninitialized] drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:741:3: warning: variable 'sec_inc' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:741:3: warning: variable 'sec_inc' is used uninitialized whenever '&&' condition is false [-Wsometimes-uninitialized] Clang is concerned with the use of stmmac_do_void_callback (which stmmac_get_timestamp and stmmac_config_sub_second_increment wrap), as it may fail to initialize these values if the if condition was ever false (meaning the callbacks don't exist). It's not wrong because the callbacks (get_timestamp and config_sub_second_increment respectively) are the ones that initialize the variables. While it's unlikely that the callbacks are ever going to disappear and make that condition false, we can easily avoid this warning by zero initialize the variables.

2019-03-07ravb: Decrease TxFIFO depth of Q3 and Q2 to oneMasaru Nagai
Hardware has the CBS (Credit Based Shaper) which affects only Q3 and Q2. When updating the CBS settings, even if the driver does so after waiting for Tx DMA finished, there is a possibility that frame data still remains in TxFIFO. To avoid this, decrease TxFIFO depth of Q3 and Q2 to one. This patch has been exercised this using netperf TCP_MAERTS, TCP_STREAM and UDP_STREAM tests run on an Ebisu board. No performance change was detected, outside of noise in the tests, both in terms of throughput and CPU utilisation.

2019-03-07platform/x86: wmi: add WMI support to MODULE_DEVICE_TABLE()Mattias Jacobsson
The kernel provides the macro MODULE_DEVICE_TABLE() where driver authors can specify their device type and their array of device_ids and thereby trigger the generation of the appropriate MODULE_ALIAS() output. This is opposed to having to specify one MODULE_ALIAS() for each device. The WMI device type is currently not supported. While using MODULE_DEVICE_TABLE() does increase the complexity as well as spreading out the implementation across the kernel, it does come with some benefits too; * It makes different drivers look more similar; if you can specify the array of device_ids any device type specific input to MODULE_ALIAS() will automatically be generated for you. * It helps each driver avoid keeping multiple versions of the same information in sync. That is, both the array of device_ids and the potential multitude of MODULE_ALIAS()'s. Add WMI support to MODULE_DEVICE_TABLE() by adding info about struct wmi_device_id in devicetable-offsets.c and add a WMI entry point in file2alias.c. The type argument for MODULE_DEVICE_TABLE(type, name) is wmi.

Therefore update wmi_dev_match()'s loop to check for an empty guid_string instead of a NULL pointer.

2019-03-07pblk: fix max_io calculationJavier González
When calculating the maximun I/O size allowed into the buffer, consider the write size (ws_opt) used by the write thread in order to cover the case in which, due to flushes, the mem and subm pointers are disaligned by (ws_opt - 1). This case currently translates into a stall when an I/O of the largest possible size is submitted.

2019-03-07cpuidle: menu: Avoid overflows when computing varianceRafael J. Wysocki
The variance computation in get_typical_interval() may overflow if the square of the value of diff exceeds the maximum for the int64_t data type value which basically is the case when it is of the order of UINT_MAX. However, data points so far in the future don't matter for idle state selection anyway, so change the initial threshold value in get_typical_interval() to INT_MAX which will cause more "outlying" data points to be discarded without affecting the selection result.

2019-03-07libbpf: force fixdep compilation at the start of the buildStanislav Fomichev
libbpf targets don't explicitly depend on fixdep target, so when we do 'make -j$(nproc)', there is a high probability, that some objects will be built before fixdep binary is available. Fix this by running sub-make; this makes sure that fixdep dependency is properly accounted for. For the same issue in perf, see commit abb26210a395 ("perf tools: Force fixdep compilation at the start of the build").
