2014-09-24gpio: Fix ngpio in gpio-xilinx driverGernot Vormayr
If one adds gpio-controller; to the chip in the devicetree, then initialization fails with 'gpiochip_find_base: cannot find free range', because ngpio is 0. This patch fixes the bug. This version includes the suggestions from Linus Walleij. Tested on ml507 board. Signed-off-by: Gernot Vormayr <gvormayr@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2014-09-23gpio: omap: Fix interrupt namesNishanth Menon
When viewing the /proc/interrupts, there is no information about which GPIO bank a specific gpio interrupt is hooked on to. This is more than a bit irritating as such information can esily be provided back to the user and at times, can be crucial for debug. So, instead of displaying something like: 31: 0 0 GPIO 0 palmas 32: 0 0 GPIO 27 mmc0 Display the following with appropriate device name: 31: 0 0 4ae10000.gpio 0 palmas 32: 0 0 4805d000.gpio 27 mmc0 This requires that we create irq_chip instance specific for each GPIO bank which is trivial to achieve.

2014-09-23gpio: Increase ARCH_NR_GPIOs to 512Mika Westerberg
Some newer Intel SoCs, like Braswell already have more than 256 GPIOs available so the default limit is exceeded. Instead of adding more architecture specific gpio.h files with custom ARCH_NR_GPIOs we increase the gpiolib default limit to be twice the current. Current generic ARCH_NR_GPIOS limit is 256 which starts to be too small for newer Intel SoCs like Braswell. In order to support GPIO controllers on these SoCs we increase ARCH_NR_GPIOS to be 512 which should be sufficient for now. The kernel size increases a bit with this change. Below is an example of x86_64 kernel image. ARCH_NR_GPIOS=256 text data bss dec hex filename 11476173 1971328 1265664 14713165 e0814d vmlinux ARCH_NR_GPIOS=512 text data bss dec hex filename 11476173 1971328 1269760 14717261 e0914d vmlinux So the BSS size and this the kernel image size increases by 4k.

2014-09-16gpio: syscon: reuse for keystone 2 socsGrygorii Strashko
On Keystone SOCs, ARM host can send interrupts to DSP cores using the DSP GPIO controller IP. Each DSP GPIO controller provides 28 IRQ signals for each DSP core. This is one of the component used by the IPC mechanism used on Keystone SOCs. Keystone 2 DSP GPIO controller has specific features: - each GPIO can be configured only as output pin; - setting GPIO value to 1 causes IRQ generation on target DSP core; - reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still pending. This patch updates gpio-syscon driver to be reused by Keystone 2 SoCs, because the Keystone 2 DSP GPIO controller is controlled through Syscon devices and, as requested by Linus Walleij, such kind of GPIO controllers should be integrated with drivers/gpio/gpio-syscon.c driver.

"gpio,syscon-dev" has following format: gpio,syscon-dev = <&syscon_dev data_reg_offset [direction_reg_offset]>; where - syscon_dev - phandle on syscon node - data_reg_offset - offset of data register (in bytes) - direction_reg_offset - offset of dirrection register (optional, in bytes) for example: gpio,syscon-dev = <&devctrl 0x254>; In such way, the support of multiple Syscon GPIO devices is added.

The current prototype of gpiochip_request_own_desc() requires to obtain a pointer to a descriptor. This is in contradiction to all other GPIO request schemes, and imposes an extra step of obtaining a descriptor to drivers. Most drivers actually cannot even perform that step since the function that does it (gpichip_get_desc()) is gpiolib-private.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull fix for ftrace function tracer/profiler conflict from Steven Rostedt: "The rewrite of the ftrace code that makes it possible to allow for separate trampolines had a design flaw with the interaction between the function and function_graph tracers. The main flaw was the simplification of the use of multiple tracers having the same filter (like function and function_graph, that use the set_ftrace_filter file to filter their code). The design assumed that the two tracers could never run simultaneously as only one tracer can be used at a time. The problem with this assumption was that the function profiler could be implemented on top of the function graph tracer, and the function profiler could run at the same time as the function tracer. This caused the assumption to be broken and when ftrace detected this failed assumpiton it would spit out a nasty warning and shut itself down. Instead of using a single ftrace_ops that switches between the function and function_graph callbacks, the two tracers can again use their own ftrace_ops. But instead of having a complex hierarchy of ftrace_ops, the filter fields are placed in its own structure and the ftrace_ops can carefully use the same filter. This change took a bit to be able to allow for this and currently only the global_ops can share the same filter, but this new design can easily be modified to allow for any ftrace_ops to share its filter with another ftrace_ops. The first four patches deal with the change of allowing the ftrace_ops to share the filter (and this needs to go to 3.16 as well). The fifth patch fixes a bug that was also caused by the new changes but only for archs other than x86, and only if those archs implement a direct call to the function_graph tracer which they do not do yet but will in the future. It does not need to go to stable, but needs to be fixed before the other archs update their code to allow direct calls to the function_graph trampoline" * tag 'trace-fixes-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Use current addr when converting to nop in __ftrace_replace_code() ftrace: Fix function_profiler and function tracer together ftrace: Fix up trampoline accounting with looping on hash ops ftrace: Update all ftrace_ops for a ftrace_hash_ops update ftrace: Allow ftrace_ops to use the hashes from other ops

2014-08-24aio: fix reqs_available handlingBenjamin LaHaise
As reported by Dan Aloni, commit f8567a3845ac ("aio: fix aio request leak when events are reaped by userspace") introduces a regression when user code attempts to perform io_submit() with more events than are available in the ring buffer. Reverting that commit would reintroduce a regression when user space event reaping is used. Fixing this bug is a bit more involved than the previous attempts to fix this regression. Since we do not have a single point at which we can count events as being reaped by user space and io_getevents(), we have to track event completion by looking at the number of events left in the event ring. So long as there are as many events in the ring buffer as there have been completion events generate, we cannot call put_reqs_available(). The code to check for this is now placed in refill_reqs_available(). A test program from Dan and modified by me for verifying this bug is available at http://www.kvack.org/~bcrl/20140824-aio_bug.c .
