2014-10-31Input: max77693-haptic - fix potential overflowDmitry Torokhov
Expression haptic->pwm_dev->period * haptic->magnitude is of type 'unsigned int' and may overflow. We need to convert one of the operands to u64 before multiplying, instead of casting result (potentially overflown) to u64.

2014-10-16Input: xen-kbdfront - free grant table entry in xenkbd_disconnect_backendChang Huaixin
xenkbd_disconnect_backend doesn't free grant table entry. This bug affects live migration. xenkbd_disconnect_backend uses gnttab_end_foreign_access_ref to handle grant table entry which doesn't really free an entry. Thus every time we do xenkbd_resume, grant table entry increses by one. As an grant table entry occupies 8 bytes, an grant table page has at most 512 entries. Every 512 times we do xenkdb_resume, grant table pages increses by one. After around 3500 times of live migration, grant table pages will increase by 7, causing too many pages to populate and hitting max_pages limit when assigning pages.Thus assign_pages will fail, so will live migration.

ACPI device enumeration mechanism changed a lot since 3.16-rc1. ACPI device objects with _HID will be enumerated to platform bus by default. For the existing PNP drivers that probe the PNPACPI devices, the device ids are listed explicitly in drivers/acpi/acpi_pnp.c. But ACPI folks will continue their effort on shrinking this id list by converting the PNP drivers to platform drivers, for the devices that don't belong to PNP bus in nature.

2014-09-11Input: introduce palmas-pwrbuttonNishanth Menon
Many palmas family of PMICs have support for interrupt based power button. This allows the device to notify the processor of external push button events over the shared palmas interrupt. However, this event is generated only during a "press" operation. Software is supposed to poll(sigh!) for detecting a release event. The PMIC also supports ability to power off independent of the software decisions when the button is pressed for a long duration if the PMIC is appropriately configured on the platform. Even though the function is similar to twl4030_pwrbutton, it is substantially different in operation to belong to a new driver of it's own.

2014-07-21sparcspkr: use sbus_*() primitives for IOSam Ravnborg
The memory are mapped using of_ioremap() which is an indication this is sbus memory. Shift all uses of inb/outb to the sbus variants. The inb/outb methods uses ASI_PHYS_BYPASS_EC_E_L, whereas sbus_ variants uses ASI_PHYS_BYPASS_EC_E. The difference is if the reads/writes are done in native or little endian. But for byte reads/writes there is no difference so this does not matter for inb/outb - and this driver only uses the byte variants.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "These cleanup patches are mainly move stuff around and should all be harmless. They are mainly split out so that other branches can be based on top to avoid conflicts. Notable changes are: - We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no longer used (Uwe Kleine-König) - The Qualcomm MSM platform is split out into legacy mach-msm and new-style mach-qcom, to allow easier maintainance of the new hardware support without regressions (Kumar Gala) - A rework of some of the Kconfig logic to simplify multiplatform support (Rob Herring) - Samsung Exynos gets closer to supporting multiplatform (Sachin Kamat and others) - mach-bcm3528 gets merged into mach-bcm (Stephen Warren) - at91 gains some common clock framework support (Alexandre Belloni, Jean-Jacques Hiblot and other French people)" * tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (89 commits) ARM: hisi: select HAVE_ARM_SCU only for SMP ARM: efm32: allow uncompress debug output ARM: prima2: build reset code standalone ARM: at91: add PWM clock ARM: at91: move sam9261 SoC to common clk ARM: at91: prepare common clk transition for sam9261 SoC ARM: at91: updated the at91_dt_defconfig with support for the ADS7846 ARM: at91: dt: sam9261: Device Tree support for the at91sam9261ek ARM: at91: dt: defconfig: Added the sam9261 to the list of DT-enabled SOCs ARM: at91: dt: Add at91sam9261 dt SoC support ARM: at91: switch sam9rl to common clock framework ARM: at91/dt: define main clk frequency of at91sam9rlek ARM: at91/dt: define at91sam9rl clocks ARM: at91: prepare common clk transition for sam9rl SoCs ARM: at91: prepare sam9 dt boards transition to common clk ARM: at91: dt: sam9rl: Device Tree for the at91sam9rlek ARM: at91/defconfig: Add the sam9rl to the list of DT-enabled SOCs ARM: at91: Add at91sam9rl DT SoC support ARM: at91: prepare at91sam9rl DT transition ARM: at91/defconfig: refresh at91sam9260_9g20_defconfig ...
