Older UltraSPARC chips had an address space hole due to the MMU only supporting 44-bit virtual addresses. The top end of this hole also has the same value as the current definition of PAGE_OFFSET, so this can be confusing. Consolidate the defines for the userspace mmap exclusion range into page_64.h and use them in sys_sparc_64.c and hugetlbpage.c Signed-off-by: NDavid S.

Pull GPIO changes from Linus Walleij: "Here is the bulk of GPIO changes for the v3.13 development cycle. I've got ACKs for the things that affect other subsystems (or it's my own subsystem, like pinctrl). Most of that pertain to an attempt from my side to consolidate and get rid of custom GPIO implementations in the ARM tree. I will continue doing this. The main change this time is the new GPIO descriptor API, background for this can be found in Corbet's summary from this january in LWN: http://lwn.net/Articles/533632/ Summary: - Merged the GPIO descriptor API from Alexandre Courbot. This is a first step toward trying to get rid of the global GPIO numberspace for the future. - Add an API so that driver can flag that a certain GPIO line is being used by a irqchip backend for generating IRQs, so that we can enforce checks, like not allowing users to switch that line to an output at runtime, since this makes no sense. Implemented corresponding calls in a few select drivers. - ACPI GPIO cleanups, refactorings and switch to using the descriptor-based interface. - Support for the TPS80036 Palmas GPIO variant. - A new driver for the Broadcom Kona GPIO SoC IP block. - Device tree support for the PCF857x driver. - A set of ARM GPIO refactorings with the goal of getting rid of a bunch of custom GPIO implementations from the arch/arm/* tree: * Move the IOP GPIO driver to the GPIO subsystem and fix all users to use the gpiolib API for accessing GPIOs. Delete the old custom GPIO implementation. * Delete the unused custom PXA GPIO implemention. * Convert all users of the IXP4 custom GPIO implementation to use gpiolib and delete the custom implementation. * Delete the custom Gemini GPIO implementation, also completely unused. - Various cleanups and renamings" * tag 'gpio-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (85 commits) gpio: gpio-mxs: Remove unneeded dt checks gpio: pl061: don't depend on CONFIG_ARM gpio: bcm-kona: add missing .owner to struct gpio_chip gpiolib: provide a declaration of seq_file in gpio/driver.h gpiolib: include gpio/consumer.h in of_gpio.h for desc_to_gpio() gpio: provide stubs for devres gpio functions gpiolib: devres: add missing headers gpiolib: make GPIO_DEVRES depend on GPIOLIB gpiolib: devres: fix devm_gpiod_get_index() gpiolib / ACPI: document the GPIO descriptor based interface gpiolib / ACPI: allow passing GPIOF_ACTIVE_LOW for GpioInt resources gpiolib / ACPI: add ACPI support for gpiod_get_index() gpiolib / ACPI: convert to gpiod interfaces gpiolib: add gpiod_get() and gpiod_put() functions gpiolib: port of_ functions to use gpiod gpiolib: export descriptor-based GPIO interface Fixup "MAINTAINERS: GPIO-INTEL-MID: add maintainer" gpio: bcm281xx: Don't print addresses of GPIO area in probe() gpio: tegra: use new gpio_lock_as_irq() API gpio: rcar: Include linux/of.h header ...

The changes hitting arch/blackfin are ACKed by the Blackfin maintainer, and the device tree bindings are ACKed to the extent possible by someone from the device tree maintainers group. - Blackfin ADI pin control driver, we move yet another architecture under this subsystem umbrella. - Incremental updates to the Renesas Super-H PFC pin control driver. New subdriver for the r8a7791 SoC. - Non-linear GPIO ranges from the gpiolib side of things, this enabled simplified device tree bindings by referring entire groups of pins on some pin controller to act as back-end for a certain GPIO-chip driver. - Add the Abilis TB10x pin control driver used on the ARC architecture. Also the corresponding GPIO driver is merged through this tree, so the ARC has full support for pins and GPIOs after this. - Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller instances. The i.MX1 and i.MX27 is an entirely new family (silicon) of controllers whereas i.MX50 is a variant of the previous supported controller. - Then the usual slew of fixes, cleanups and incremental updates" The ARC DT changes are apparently still pending, that hopefully gets sorted out in a timely manner. * tag 'pinctrl-for-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (48 commits) pinctrl: imx50: add pinctrl support code for the IMX50 SoC pinctrl: at91: copy define to driver pinctrl: remove minor dead code pinctrl: imx: fix using pin->input_val wrongly pinctrl: imx1: fix return value check in imx1_pinctrl_core_probe() gpio: tb10x: fix return value check in tb10x_gpio_probe() gpio: tb10x: use module_platform_driver to simplify the code pinctrl: imx27: imx27 pincontrol driver pinctrl: imx1 core driver pinctrl: sh-pfc: r8a7791 PFC support sh-pfc: r8a7778: Add CAN pin groups gpio: add TB10x GPIO driver pinctrl: at91: correct a few typos pinctrl: mvebu: remove redundant of_match_ptr pinctrl: tb10x: use module_platform_driver to simplify the code pinctrl: tb10x: fix the error handling in tb10x_pinctrl_probe() pinctrl: add documentation for pinctrl_get_group_pins() pinctrl: rockchip: emulate both edge triggered interrupts pinctrl: rockchip: add rk3188 specifics pinctrl: rockchip: remove redundant check ...

Pull perf updates from Ingo Molnar: "As a first remark I'd like to note that the way to build perf tooling has been simplified and sped up, in the future it should be enough for you to build perf via: cd tools/perf/ make install (ie without the -j option.) The build system will figure out the number of CPUs and will do a parallel build+install. The various build system inefficiencies and breakages Linus reported against the v3.12 pull request should now be resolved - please (re-)report any remaining annoyances or bugs. Main changes on the perf kernel side: * Performance optimizations: . perf ring-buffer code optimizations, by Peter Zijlstra . perf ring-buffer code optimizations, by Oleg Nesterov . x86 NMI call-stack processing optimizations, by Peter Zijlstra . perf context-switch optimizations, by Peter Zijlstra . perf sampling speedups, by Peter Zijlstra . x86 Intel PEBS processing speedups, by Peter Zijlstra * Enhanced hardware support: . for Intel Ivy Bridge-EP uncore PMUs, by Zheng Yan . for Haswell transactions, by Andi Kleen, Peter Zijlstra * Core perf events code enhancements and fixes by Oleg Nesterov: . for uprobes, if fork() is called with pending ret-probes . for uprobes platform support code * New ABI details by Andi Kleen: . Report x86 Haswell TSX transaction abort cost as weight Main changes on the perf tooling side (some of these tooling changes utilize the above kernel side changes): * 'perf report/top' enhancements: . Convert callchain children list to rbtree, greatly reducing the time taken for callchain processing, from Namhyung Kim. . Add new COMM infrastructure, further improving histogram processing, from Frédéric Weisbecker, one fix from Namhyung Kim. . Add /proc/kcore based live-annotation improvements, including build-id cache support, multi map 'call' instruction navigation fixes, kcore address validation, objdump workarounds. From Adrian Hunter. . Show progress on histogram collapsing, that can take a long time, from Namhyung Kim. . Add --max-stack option to limit callchain stack scan in 'top' and 'report', improving callchain processing when reducing the stack depth is an option, from Waiman Long. . Add new option --ignore-vmlinux for perf top, from Willy Tarreau. * 'perf trace' enhancements: . 'perf trace' now can can use a 'perf probe' dynamic tracepoints to hook into the userspace -> kernel pathname copy so that it can map fds to pathnames without reading /proc/pid/fd/ symlinks. From Arnaldo Carvalho de Melo. . Show VFS path associated with fd in live sessions, using a 'vfs_getname' 'perf probe' created dynamic tracepoint or by looking at /proc/pid/fd, from Arnaldo Carvalho de Melo. .
