2016-01-18ARM: debug-ll: fix BCM63xx entry for multiplatformArnd Bergmann
During my randconfig build testing, I found that a kernel with DEBUG_AT91_UART and ARCH_BCM_63XX fails to build: arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror] It turns out that the DEBUG_UART_BCM63XX option is enabled whenever the ARCH_BCM_63XX is, and that breaks multiplatform kernels because we then end up using the UART address from BCM63XX rather than the one we actually configured (if any). This changes the BCM63XX options to only have one Kconfig option, and only enable that if the user explicitly turns it on.

2016-01-18ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHzGeert Uytterhoeven
On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from 25 MHz to 24 MHz to fix this. This matches the Armadillo-800 EVA Product Manual, which claims the main crystal runs at 24 MHz, and the old legacy/reference board code.

2016-01-17Merge tag 'gpio-v4.5-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "Here is the bulk of GPIO changes for v4.5. Notably there are big refactorings mostly by myself, aimed at getting the gpio_chip into a shape that makes me believe I can proceed to preserve state for a proper userspace ABI (character device) that has already been proposed once, but resulted in the feedback that I need to go back and restructure stuff. So I've been restructuring stuff. On the way I ran into brokenness (return code from the get_value() callback) and had to fix it. Also, refactored generic GPIO to be simpler. Some of that is still waiting to trickle down from the subsystems all over the kernel that provide random gpio_chips, I've touched every single GPIO driver in the kernel now, oh man I didn't know I was responsible for so much... Apart from that we're churning along as usual. I took some effort to test and retest so it should merge nicely and we shook out a couple of bugs in -next. Infrastructural changes: - In struct gpio_chip, rename the .dev node to .parent to better reflect the fact that this is not the GPIO struct device abstraction. We will add that soon so this would be totallt confusing. - It was noted that the driver .get_value() callbacks was sometimes reporting negative -ERR values to the gpiolib core, expecting them to be propagated to consumer gpiod_get_value() and gpio_get_value() calls. This was not happening, so as there was a mess of drivers returning negative errors and some returning "anything else than zero" to indicate that a line was active. As some would have bit 31 set to indicate "line active" it clashed with negative error codes. This is fixed by the largeish series clamping values in all drivers with !!value to [0,1] and then augmenting the code to propagate error codes to consumers. (Includes some ACKed patches in other subsystems.) - Add a void *data pointer to struct gpio_chip. The container_of() design pattern is indeed very nice, but we want to reform the struct gpio_chip to be a non-volative, stateless business, and keep states internal to the gpiolib to be able to hold on to the state when adding a proper userspace ABI (character device) further down the road. To achieve this, drivers need a handle at the internal state that is not dependent on their struct gpio_chip() so we add gpiochip_add_data() and gpiochip_get_data() following the pattern of many other subsystems. All the "use gpiochip data pointer" patches transforms drivers to this scheme. - The Generic GPIO chip header has been merged into the general <linux/gpio/driver.h> header, and the custom header for that removed. Instead of having a separate mm_gpio_chip struct for these generic drivers, merge that into struct gpio_chip, simplifying the code and removing the need for separate and confusing includes. Misc improvements: - Stabilize the way GPIOs are looked up from the ACPI legacy specification. - Incremental driver features for PXA, PCA953X, Lantiq (patches from the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48 New drivers: - Add a GPIO chip to the ALSA SoC AC97 driver. - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but the branch is merged here too to account for infrastructural changes). - The sx150x driver now supports the sx1502" * tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (220 commits) gpio: generic: make bgpio_pdata always visible gpiolib: fix chip order in gpio list gpio: mpc8xxx: Do not use gpiochip_get_data() in mpc8xxx_gpio_save_regs() gpio: mm-lantiq: Do not use gpiochip_get_data() in ltq_mm_save_regs() gpio: brcmstb: Allow building driver for BMIPS_GENERIC gpio: brcmstb: Set endian flags for big-endian MIPS gpio: moxart: fix build regression gpio: xilinx: Do not use gpiochip_get_data() in xgpio_save_regs() leds: pca9532: use gpiochip data pointer leds: tca6507: use gpiochip data pointer hid: cp2112: use gpiochip data pointer bcma: gpio: use gpiochip data pointer avr32: gpio: use gpiochip data pointer video: fbdev: via: use gpiochip data pointer gpio: pch: Optimize pch_gpio_get() Revert "pinctrl: lantiq: Implement gpio_chip.to_irq" pinctrl: nsp-gpio: use gpiochip data pointer pinctrl: vt8500-wmt: use gpiochip data pointer pinctrl: exynos5440: use gpiochip data pointer pinctrl: at91-pio4: use gpiochip data pointer ...

2016-01-16Kconfig: remove HAVE_LATENCYTOP_SUPPORTWill Deacon
As illustrated by commit a3afe70b83fd ("[S390] latencytop s390 support."), HAVE_LATENCYTOP_SUPPORT is defined by an architecture to advertise an implementation of save_stack_trace_tsk. However, as of 9212ddb5eada ("stacktrace: provide save_stack_trace_tsk() weak alias") a dummy implementation is provided if STACKTRACE=y. Given that LATENCYTOP already depends on STACKTRACE_SUPPORT and selects STACKTRACE, we can remove HAVE_LATENCYTOP_SUPPORT altogether.

2016-01-15kvm: rename pfn_t to kvm_pfn_tDan Williams
To date, we have implemented two I/O usage models for persistent memory, PMEM (a persistent "ram disk") and DAX (mmap persistent memory into userspace). This series adds a third, DAX-GUP, that allows DAX mappings to be the target of direct-i/o. It allows userspace to coordinate DMA/RDMA from/to persistent memory. The implementation leverages the ZONE_DEVICE mm-zone that went into 4.3-rc1 (also discussed at kernel summit) to flag pages that are owned and dynamically mapped by a device driver. The pmem driver, after mapping a persistent memory range into the system memmap via devm_memremap_pages(), arranges for DAX to distinguish pfn-only versus page-backed pmem-pfns via flags in the new pfn_t type. The DAX code, upon seeing a PFN_DEV+PFN_MAP flagged pfn, flags the resulting pte(s) inserted into the process page tables with a new _PAGE_DEVMAP flag. Later, when get_user_pages() is walking ptes it keys off _PAGE_DEVMAP to pin the device hosting the page range active. Finally, get_page() and put_page() are modified to take references against the device driver established page mapping. Finally, this need for "struct page" for persistent memory requires memory capacity to store the memmap array. Given the memmap array for a large pool of persistent may exhaust available DRAM introduce a mechanism to allocate the memmap from persistent memory. The new "struct vmem_altmap *" parameter to devm_memremap_pages() enables arch_add_memory() to use reserved pmem capacity rather than the page allocator. This patch (of 18): The core has developed a need for a "pfn_t" type [1]. Move the existing pfn_t in KVM to kvm_pfn_t [2].

2016-01-15mm: differentiate page_mapped() from page_mapcount() for compound pagesKirill A. Shutemov
Let's define page_mapped() to be true for compound pages if any sub-pages of the compound page is mapped (with PMD or PTE). On other hand page_mapcount() return mapcount for this particular small page. This will make cases like page_get_anon_vma() behave correctly once we allow huge pages to be mapped with PTE. Most users outside core-mm should use page_mapcount() instead of page_mapped(). Signed-off-by: Kirill A.

2016-01-14arm: mm: support ARCH_MMAP_RND_BITSDaniel Cashman
arm: arch_mmap_rnd() uses a hard-code value of 8 to generate the random offset for the mmap base address. This value represents a compromise between increased ASLR effectiveness and avoiding address-space fragmentation. Replace it with a Kconfig option, which is sensibly bounded, so that platform developers may choose where to place this compromise. Keep 8 as the minimum acceptable value.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The bulk of this has appeared in -next and independently received a build success notification from the kbuild robot. The 'for-4.5/block- dax' topic branch was rebased over the weekend to drop the "block device end-of-life" rework that Al would like to see re-implemented with a notifier, and to address bug reports against the badblocks integration. There is pending feedback against "libnvdimm: Add a poison list and export badblocks" received last week. Linda identified some localized fixups that we will handle incrementally. Summary: - Media error handling: The 'badblocks' implementation that originated in md-raid is up-levelled to a generic capability of a block device. This initial implementation is limited to being consulted in the pmem block-i/o path. Later, 'badblocks' will be consulted when creating dax mappings. - Raw block device dax: For virtualization and other cases that want large contiguous mappings of persistent memory, add the capability to dax-mmap a block device directly. - Increased /dev/mem restrictions: Add an option to treat all io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is actively using an address range. This behavior is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the existing "iomem=relaxed" kernel command line option. - Miscellaneous fixes include a 'pfn'-device huge page alignment fix, block device shutdown crash fix, and other small libnvdimm fixes" * tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (32 commits) block: kill disk_{check|set|clear|alloc}_badblocks libnvdimm, pmem: nvdimm_read_bytes() badblocks support pmem, dax: disable dax in the presence of bad blocks pmem: fail io-requests to known bad blocks libnvdimm: convert to statically allocated badblocks libnvdimm: don't fail init for full badblocks list block, badblocks: introduce devm_init_badblocks block: clarify badblocks lifetime badblocks: rename badblocks_free to badblocks_exit libnvdimm, pmem: move definition of nvdimm_namespace_add_poison to nd.h libnvdimm: Add a poison list and export badblocks nfit_test: Enable DSMs for all test NFITs md: convert to use the generic badblocks code block: Add badblock management for gendisks badblocks: Add core badblock management code block: fix del_gendisk() vs blkdev_ioctl crash block: enable dax for raw block devices block: introduce bdev_file_inode() restrict /dev/mem to idle io memory ranges arch: consolidate CONFIG_STRICT_DEVM in lib/Kconfig.debug ...

This aids improved helpers and should make certain abstractions easier in the future. Also causes a lot of churn, helped along by some automated code transformations - add more core support for detecting (and "correcting") bitflips in erased pages; requires opt-in by drivers, but at least we kill a few bad implementations and hopefully stave off future ones - pxa3xx_nand: cleanups, a few fixes, and PM improvements - new JZ4780 NAND driver SPI NOR: - provide default erase function, for controllers that just want to send the SECTOR_ERASE command directly - fix some module auto-loading issues with device tree ("jedec,spi-nor") - error handling fixes - new Mediatek QSPI flash driver Other: - cfi: force valid geometry Kconfig (finally!)

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull oower management and ACPI updates from Rafael Wysocki: "As far as the number of commits goes, ACPICA takes the lead this time, followed by cpufreq and the device properties framework changes. The most significant new feature is the debugfs-based interface to the ACPICA's AML debugger added in the previous cycle and a new user space tool for accessing it. On the cpufreq front, the core is updated to handle governors more efficiently, particularly on systems where a single cpufreq policy object is shared between multiple CPUs, and there are quite a few changes in drivers (intel_pstate, cpufreq-dt etc). The device properties framework is updated to handle built-in (ie included in the kernel itself) device properties better, among other things by adding a fallback mechanism that will allow drivers to provide default properties to be used in case the plaform firmware doesn't provide the properties expected by them. The Operating Performance Points (OPP) framework gets new DT bindings and debugfs support. A new cpufreq driver for ST platforms is added and the ACPI driver for AMD SoCs will now support the APM X-Gene ACPI I2C device. The rest is mostly fixes and cleanups all over. Specifics: - Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki). In particular, the previously added erroneous support for the _SUB object is dropped, the concatenate operator will support all ACPI objects now, the Debug Object handling is improved, the SuperName handling of parameters being control methods is fixed, the ObjectType operator handling is updated to follow ACPI 5.0A and the handling of CondRefOf and RefOf is updated accordingly, module- level code will be executed after loading each ACPI table now (instead of being run once after all tables containing AML have been loaded), the Operation Region handlers management is updated to fix some reported problems and a the ACPICA code in the kernel is more in line with the upstream now. - Update the ACPI backlight driver to provide information on whether or not it will generate key-presses for brightness change hotkeys and update some platform drivers (dell-wmi, thinkpad_acpi) to use that information to avoid sending double key-events to users pace for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht). - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard). - Fix the handling of the list of device IDs of device objects found in the ACPI namespace and add a helper for checking if there is a device object for a given device ID (Lukas Wunner). - Change the logic in the ACPI namespace scanning code to create struct acpi_device objects for all ACPI device objects found in the namespace even if _STA fails for them which helps to avoid device enumeration problems on Microsoft Surface 3 (Aaron Lu). - Add support for the APM X-Gene ACPI I2C device to the ACPI driver for AMD SoCs (Loc Ho). - Fix the long-standing issue with the DMA controller on Intel SoCs where ACPI tables have no power management support for the DMA controller itself, but it can be powered off automatically when the last (other) device on the SoC is powered off via ACPI and clean up the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts to fix that problem (Andy Shevchenko). - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King, Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki, Sinan Kaya). - Update the device properties framework for better handling of built-in properties, add support for built-in properties to the platform bus type, update the MFD subsystem's handling of device properties and add support for passing default configuration data as device properties to the intel-lpss MFD drivers, convert the designware I2C driver to use the unified device properties API and add a fallback mechanism for using default built-in properties if the platform firmware fails to provide the properties as expected by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus, Andrew Morton). - Add new Device Tree bindings to the Operating Performance Points (OPP) framework and update the exynos4412 DT binding accordingly, introduce debugfs support for the OPP framework (Viresh Kumar, Bartlomiej Zolnierkiewicz). - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng Chen). - Update the cpufreq core to make the handling of governors more efficient, especially on systems where policy objects are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki). - Fix cpufreq governor handling on configurations with CONFIG_HZ_PERIODIC set (Chen Yu). - Clean up the cpufreq core code related to the boost sysfs knob support and update the ACPI cpufreq driver accordingly (Rafael Wysocki). - Add a new cpufreq driver for ST platforms and corresponding Device Tree bindings (Lee Jones). - Update the intel_pstate driver to allow the P-state selection algorithm used by it to depend on the CPU ID of the processor it is running on, make it use a special P-state selection algorithm (with an IO wait time compensation tweak) on Atom CPUs based on the Airmont and Silvermont cores so as to reduce their energy consumption and improve intel_pstate documentation (Philippe Longepe, Srinivas Pandruvada). - Update the cpufreq-dt driver to support registering cooling devices that use the (P * V^2 * f) dynamic power draw formula where V is the voltage, f is the frequency and P is a constant coefficient provided by Device Tree and update the arm_big_little cpufreq driver to use that support (Punit Agrawal). - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq, blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob Tanenbaum, Markus Elfring). - cpuidle core tweaks related to polling and measured_us calculation (Rik van Riel). - Removal of modularity from a few cpuidle drivers (clps711x, ux500, exynos) that cannot be built as modules in practice (Paul Gortmaker). - PM core update to prevent devices from being probed during system suspend/resume which is generally problematic and may lead to inconsistent behavior (Grygorii Strashko). - Assorted updates of the PM core and related code (Julia Lawall, Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf Hansson). - PNP bus type updates (Christophe Le Roy, Heiner Kallweit). -

2016-01-11ARM: dts: Fix omap5 PMIC control lines for RTC writesTony Lindgren
The palmas PMIC has two control lines that need to be muxed properly for things to work. The sys_nirq pin is used for interrupts, and msecure pin is used for enabling writes to some PMIC registers. Without these pins configured properly things can fail in mysterious ways. For example, we can't update the RTC registers on palmas PMIC unless the msecure pin is configured. And this is probably the reason why we had RTC missing from the omap5 dts file. According to "OMAP5430 ES2.0 Data Manual [Public] VErsion A (Rev. F)" swps052f.pdf, mux mode 1 is for sys_drm_msecure so in theory there's should be no need to configure it as a GPIO pin. However, it seems there are some reliability issues using the msecure mux mode. And the TI trees configure the msecure pin as GPIO out high instead. As the PMIC only cares that the msecure line is high to allow access to the RTC registers, let's use a GPIO hog as suggested by Nishanth Menon <nm@ti.com>. Also the use of the internal pull was considered but supposedly that may not be capable of keeping the line high in a noisy environment. If we ever see high security omap5 products in the mainline tree, those need to skip the msecure pin muxing and ignore setting the GPIO hog. Chances are the related pin mux registers are locked in that case and the msecure pin is managed by whatever software may be running in the ARM TrustZone. Who knows what the original intention of the msecure pin was. Maybe it was supposed to prevent the system time to be set back for some game demo modes to time out? Anyways, it seems that later PMICs like tps659037 have recycled this pin for "powerhold" and devices like beagle-x15 do not need changes to the msecure pin configuration. To avoid further confusion with TWL variant PMICs, beagle-x15 does not have a back-up battery for RTC palmas. Instead the mcp79410 RTC is used with rtc-ds1307 driver. There is a "powerhold" jumper j5 holes near the palmas PMIC, and shorting it seems to power up beagle-x15 automatically. It is unknown if it also has other side effects to the beagle-x15 power up sequence. Cc: stable@vger.kernel.org # v4.4 Signed-off-by: Tony Lindgren <tony@atomide.com>

Looks like we have a GPMC bus timing bug that has gone unnoticed because of bootloader configured registers until few days ago. We are not detecting the onenand clock rate properly unless we have CONFIG_OMAP_GPMC_DEBUG set and this causes onenand corruption that can be easily be reproduced. There seems to be also an additional bug still lurking around for onenand corruption. But that is still being investigated and it does not seem to be GPMC timings related. Meanwhile, it would be good to get this fix into v4.4 to prevent wrong timings from corrupting onenand. * tag 'omap-for-v4.4/onenand-corruption' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruption
