2016-03-14avr32: fix asm operand constraint in cmpxchg()Mans Rullgard
If the 'old' operand to cmpxchg() is a constant wider than 21 bits, linking fails with a "relocation truncated to fit: R_AVR32_21S" error. Fix this by replacing the "i" constraint with "Ks21" which makes the compiler use a temporary register for out of range constants.

2016-03-14avr32: wire up copy_file_range syscallHans-Christian Egtvedt
This patch wires up the new copy_file_range syscall on AVR32. On AVR32, all parameters beyond the 5th are passed on the stack. System calls don't use the stack -- they borrow a callee-saved register instead. This means that syscalls that take 6 parameters must be called through a stub that pushes the last parameter on the stack. Signed-off-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no>

2016-03-14leds: Add driver for the ISSI IS31FL32xx family of LED controllersDavid Rivshin
The IS31FL32xx family of LED controllers are I2C devices with multiple constant-current channels, each with independent 256-level PWM control. Datasheets: http://www.issi.com/US/product-analog-fxled-driver.shtml This has been tested on the IS31FL3236 and IS31FL3216, on an ARM (TI am335x) platform. The programming paradigm of these devices is similar in the following ways: - All registers are 8 bit - All LED control registers are write-only - Each LED channel has a PWM register (0-255) - PWM register writes are shadowed until an Update register is poked - All have a concept of Software Shutdown, which disables output However, there are some differences in devices: - 3236/3235 have a separate Control register for each LED, (3218/3216 pack the enable bits into fewer registers) - 3236/3235 have a per-channel current divisor setting - 3236/3235 have a Global Control register that can turn off all LEDs - 3216 is unique in a number of ways - OUT9-OUT16 can be configured as GPIOs instead of LED controls - LEDs can be programmed with an 8-frame animation, with programmable delay between frames - LEDs can be modulated by an input audio signal - Max output current can be adjusted from 1/4 to 2x globally - Has a Configuration register instead of a Shutdown register This driver currently only supports the base PWM control function of these devices. The following features of these devices are not implemented, although it should be possible to add them in the future: - All devices are capable of going into a lower-power "software shutdown" mode. - The is31fl3236 and is31fl3235 can reduce the max output current per-channel with a divisor of 1, 2, 3, or 4. - The is31fl3216 can use some LED channels as GPIOs instead. - The is31fl3216 can animate LEDs in hardware. - The is31fl3216 can modulate LEDs according to an audio input. - The is31fl3216 can reduce/increase max output current globally.

2016-03-14leds: core: avoid error message when a USB LED device is unpluggedHeiner Kallweit
When a USB LED device is unplugged the remove call chain calls led_classdev_unregister which tries to switch the LED off. As the device has been removed already this results in a ENODEV error message in dmesg. Avoid this error message by ignoring ENODEV in calls from led_classdev_unregister if the LED device is flagged as pluggable. Therefore a new flag LED_HW_PLUGGABLE was introduced which should be set by all LED drivers handling pluggable LED devices (mainly USB LED devices).

2016-03-13MIPS: smp.c: Fix uninitialised temp_foreign_mapJames Hogan
When calculate_cpu_foreign_map() recalculates the cpu_foreign_map cpumask it uses the local variable temp_foreign_map without initialising it to zero. Since the calculation only ever sets bits in this cpumask any existing bits at that memory location will remain set and find their way into cpu_foreign_map too. This could potentially lead to cache operations suboptimally doing smp calls to multiple VPEs in the same core, even though the VPEs share primary caches. Therefore initialise temp_foreign_map using cpumask_clear() before use.

2016-03-13MIPS: Fix build error when SMP is used without GICHauke Mehrtens
The MIPS_GIC_IPI should only be selected when MIPS_GIC is also selected, otherwise it results in a compile error. smp-gic.c uses some functions from include/linux/irqchip/mips-gic.h like plat_ipi_call_int_xlate() which are only added to the header file when MIPS_GIC is set. The Lantiq SoC does not use the GIC, but supports SMP.

Ingenic SoC declares ZBOOT support, but debug definitions are missing for MACH_JZ4780 resulting in a build failure when DEBUG_ZBOOT is set. The UART addresses are same as with JZ4740, so fix by covering JZ4780 with those as well.

2016-03-13tools/power turbostat: bugfix: TDP MSRs print bits fixingChen Yu
MSR_CONFIG_TDP_NOMINAL: should print all 8 bits of base_ratio (bit 0:7) 0xFF MSR_CONFIG_TDP_LEVEL_1: should print all 15 bits of PKG_MIN_PWR_LVL1 (bit 48:62) 0x7FFF should print all 15 bits of PKG_MAX_PWR_LVL1 (bit 32:46) 0x7FFF should print all 8 bits of LVL1_RATIO (bit 16:23) 0xFF should print all 15 bits of PKG_TDP_LVL1 (bit 0:14) 0x7FFF And the same modification to MSR_CONFIG_TDP_LEVEL_2. MSR_TURBO_ACTIVATION_RATIO: should print all 8 bits of MAX_NON_TURBO_RATIO (bit 0:7) 0xFF Signed-off-by: Chen Yu <yu.c.chen@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
