Pull bulk of gpio updates from Linus Walleij: "A pretty big chunk of changes this time, but it has all been on rotation in linux-next and had some testing. Of course there will be some amount of fixes on top... - Merged in a branch of irqchip changes from Thomas Gleixner: we need to have new callbacks from the irqchip to determine if the GPIO line will be eligible for IRQs, and this callback must be able to say "no". After some thinking I got the branch from tglx and have switched all current users over to use this. - Based on tglx patches, we have added some generic irqchip helpers in the gpiolib core. These will help centralize code when GPIO drivers have simple chained/cascaded IRQs. Drivers will still define their irqchip vtables, but the gpiolib core will take care of irqdomain set-up, mapping from local offsets to Linux irqs, and reserve resources by marking the GPIO lines for IRQs. - Initially the PL061 and Nomadik GPIO/pin control drivers have been switched over to use the new gpiochip-to-irqchip infrastructure with more drivers expected for the next kernel cycle. The factoring of just two drivers still makes it worth it so it is already a win. - A new driver for the Synopsys DesignWare APB GPIO block. - Modify the DaVinci GPIO driver to be reusable also for the new TI Keystone architecture. - A new driver for the LSI ZEVIO SoCs. - Delete the obsolte tnetv107x driver. - Some incremental work on GPIO descriptors: have gpiod_direction_output() use a logical level, respecting assertion polarity through ACTIVE_LOW flags, adding gpiod_direction_output_raw() for the case where you want to set that very value. Add gpiochip_get_desc() to fetch a GPIO descriptor from a specific offset on a certain chip inside driver code. - Switch ACPI GPIO code over to using gpiochip_get_desc() and get rid of gpio_to_desc(). - The ACPI GPIO event handling code has been reworked after encountering an actual real life implementation. - Support for ACPI GPIO operation regions. - Generic GPIO chips can now be assigned labels/names from platform data. - We now clamp values returned from GPIO drivers to the boolean [0,1] range. - Some improved documentation on how to use the polarity flag was added. - a large slew of incremental driver updates and non-critical fixes.

Add code to check sizes of on-disk data of metadata files such as inode size, segment usage size, DAT entry size, and checkpoint size. Although these sizes are read from disk, the current implementation doesn't check them. If these sizes are not sane on disk, it can cause out-of-range access to metadata or memory access overrun on metadata block buffers due to overflow in sundry calculations. Both lower limit and upper limit of metadata sizes are verified to prevent these issues. Signed-off-by:

With this ioctl the segment usage entries in the SUFILE can be updated from userspace. This is useful, because it allows the userspace GC to modify and update segment usage entries for specific segments, which enables it to avoid unnecessary write operations. If a segment needs to be cleaned, but there is no or very little reclaimable space in it, the cleaning operation basically degrades to a useless moving operation. In the end the only thing that changes is the location of the data and a timestamp in the segment usage information. With this ioctl the GC can skip the cleaning and update the segment usage entries directly instead. This is basically a shortcut to cleaning the segment. It is still necessary to read the segment summary information, but the writing of the live blocks can be skipped if it's not worth it.

The patch "rtc: verify a critical argument to rtc_update_irq() before using it" introduces validation for rtc_device in the RTC core, so there are no need to check this argument for rtc_update_irq() from the drivers.

NO_IRQ may be defined as '(unsigned int) -1' in some architectures (arm, sh ...), and either may not be defined in some architectures (arm64) which can enable RTC_DRV_S3C. Also since platform_get_irq returns err-code in case of any error, we do not need to intialize s3c_rtc_alarmno and s3c_rtc_tickno. Signed-off-by:

Using platform_get_irq_byname() to retrieve the IRQ number returns the VIRQ number rather than the local IRQ number for the device. Passing that value then into regmap_irq_get_virq() causes a failure because the function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc). This patch removes use of regmap_irq_get_virq() to prevent this failure from happening Signed-off-by:
