2013-12-20ARM: s3c64xx: get rid of custom <mach/gpio.h>Linus Walleij26-10/+33
This isolates the custom S3C64xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x64xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead roof the number of GPIOs for this platform: First sum up all the GPIO banks from A to Q: 187 GPIOs. Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA, 128, so in total maximum 187+16+128 = 331 GPIOs, so let's take the same roof as for S3C24XX: 512. This way we can do away with the GPIO calculation macros for GPIO_BOARD_START, BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff. The biggest this can ever be for the S3C24XX is CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512 is the absolute roof value on this platform. So we set the size of ARCH_NR_GPIO to this and the GPIOs array will fit any S3C24XX platform, as per pattern from other archs. ChangeLog v2->v3: - Move the movement of the S3C64XX gpio.h file out of this patch and into the follow-up patch where it belongs. ChangeLog v1->v2: - Added an #ifdef ARCH_S3C24XX around the header inclusion in drivers/gpio/gpio-samsung.c as we would otherwise have colliding definitions when compiling S3C64XX. - Rename inclusion guard in the header file.

2013-12-12gpiolib: return -ENOENT if no GPIO mapping existsAlexandre Courbot2-18/+22
Some devices drivers make use of optional GPIO parameters. For such drivers, it is important to discriminate between the case where no GPIO mapping has been defined for the function they are requesting, and the case where a mapping exists but an error occured while resolving it or when acquiring the GPIO. This patch changes the family of gpiod_get() functions such that they will return -ENOENT if and only if no GPIO mapping is defined for the requested function. Other error codes are used when an actual error occured during the GPIO resolution.

2013-12-09gpio: better lookup method for platform GPIOsAlexandre Courbot3-72/+85
Change the format of the platform GPIO lookup tables to make them less confusing and improve lookup efficiency. The previous format was a single linked-list that required to compare the device name and function ID of every single GPIO defined for each lookup. Switch that to a list of per-device tables, so that the lookup can be done in two steps, omitting the GPIOs that are not relevant for a particular device. The matching rules are now defined as follows: - The device name must match *exactly*, and can be NULL for GPIOs not assigned to a particular device, - If the function ID in the lookup table is NULL, the con_id argument of gpiod_get() will not be used for lookup. However, if it is defined, it must match exactly. - The index must always match.

This was prevalent when FTRACE_SELFTEST was enabled which enables all events several times, and caused the system bootup to pause for over a minute. This was tracked down to an addition of a synchronize_sched() performed when system call tracepoints are unregistered. The synchronize_sched() is needed between the unregistering of the system call tracepoint and a deletion of a tracing instance buffer. But placing the synchronize_sched() in the unreg of *every* system call tracepoint is a bit overboard.

2013-12-05tracing: Only run synchronize_sched() at instance deletion timeSteven Rostedt2-10/+3
It has been reported that boot up with FTRACE_SELFTEST enabled can take a very long time. There can be stalls of over a minute. This was tracked down to the synchronize_sched() called when a system call event is disabled. As the self tests enable and disable thousands of events, this makes the synchronize_sched() get called thousands of times. The synchornize_sched() was added with d562aff93bfb53 "tracing: Add support for SOFT_DISABLE to syscall events" which caused this regression (added in 3.13-rc1). The synchronize_sched() is to protect against the events being accessed when a tracer instance is being deleted. When an instance is being deleted all the events associated to it are unregistered. The synchronize_sched() makes sure that no more users are running when it finishes. Instead of calling synchronize_sched() for all syscall events, we only need to call it once, after the events are unregistered and before the instance is deleted. The event_mutex is held during this action to prevent new users from enabling events.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "A usual pattern of half ASoC and half HD-audio fixes, although HD-audio fixups have more volumes, in addition to a couple of trivial fixes. Nothing to worry much is found here. For ASoC side: a few fixes for PCM rate constraints calculations, regmap byte-order fix, the rest driver specific fixes (atmel, fsl, omap, kirkwood, wm codecs).

2013-12-05blk-mq: fix use-after-free of requestMing Lei1-2/+2
If accounting is on, we will do the IO completion accounting after we have freed the request. Fix that by moving it sooner instead. Signed-off-by: Jens Axboe <axboe@kernel.dk>

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 and EFI fixes from Peter Anvin: "Half of these are EFI-related: The by far biggest change is the change to hold off the deletion of a sysfs entry while a backend scan is in progress. This is to avoid calling kmemdup() while under a spinlock. The other major change is for each entry in the EFI pstore backend to get a unique identifier, as required by the pstore filesystem proper. The other changes are: A fix to the recent consolidation and optimization of using "asm goto" with read-modify-write operation, which broke the bitops; specifically in such a way that we could end up generating invalid code. A build hack to make sure we compile with -mno-sse. icc, and most likely future versions of gcc, can generate SSE instructions unless we tell it not to. A comment-only patch to a change the was due in part to an unpublished erratum; now when the erratum is published we want to add a comment explaining why" * 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/apic, doc: Justification for disabling IO APIC before Local APIC x86, bitops: Correct the assembly constraints to testing bitops x86-64, build: Always pass in -mno-sse efi-pstore: Make efi-pstore return a unique id x86/efi: Fix earlyprintk off-by-one bug efivars, efi-pstore: Hold off deletion of sysfs entry until the scan is completed
