2017-11-30RISC-V: Flush I$ when making a dirty page executableAndrew Waterman
The RISC-V ISA allows for instruction caches that are not coherent WRT stores, even on a single hart. As a result, we need to explicitly flush the instruction cache whenever marking a dirty page as executable in order to preserve the correct system behavior. Local instruction caches aren't that scary (our implementations actually flush the cache, but RISC-V is defined to allow higher-performance implementations to exist), but RISC-V defines no way to perform an instruction cache shootdown. When explicitly asked to do so we can shoot down remote instruction caches via an IPI, but this is a bit on the slow side. Instead of requiring an IPI to all harts whenever marking a page as executable, we simply flush the currently running harts. In order to maintain correct behavior, we additionally mark every other hart as needing a deferred instruction cache which will be taken before anything runs on it.

2017-11-30net: dsa: bcm_sf2: Set correct CHAIN_ID and slice number maskFlorian Fainelli
When configuring an IPv6 address mask, we should use SLICE_NUM_MASK as the mask in order to make sure all bits are masked by the hardware. Also, we want matching entries to have a CHAIN_ID value set to the same value as the rule index we return to user-space for convenience, so fix that too.

2017-11-30RISC-V: io.h: type fixes for warningsOlof Johansson

Finally, explicitly promote the base address for INB/OUTB functions to avoid some old legacy drivers complaining about int-to-ptr promotions. The drivers are unlikely to work but they're included in allmodconfig so the warnings are noisy. Fixes, among other warnings, these with allmodconfig: ../arch/riscv/include/asm/io.h:24:21: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token extern void __iomem *ioremap(phys_addr_t offset, unsigned long size); sound/pci/echoaudio/echoaudio.c: In function 'snd_echo_free': sound/pci/echoaudio/echoaudio.c:1879:10: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [-Wdiscarded-qualifiers] Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>

2017-11-30xfs: Properly retry failed dquot items in case of error during buffer writebackCarlos Maiolino
Once the inode item writeback errors is already fixed, it's time to fix the same problem in dquot code. Although there were no reports of users hitting this bug in dquot code (at least none I've seen), the bug is there and I was already planning to fix it when the correct approach to fix the inodes part was decided.

Commit 7ebc194d0fd4bb0f ("gpio: 74x164: Introduce 'enable-gpios' property") added a new member gpiod_oe to the end of the struct gen_74x164_chip, after the zero-length buffer array. However, this buffer is a flexible array, allocated together with the structure during .probe(). As the buffer is no longer the last member, writing to it corrupts the newly added member after it. During device removal, the corrupted member will be used as a pointer, leading to a crash. This went unnoticed, as the flexible array was declared as "buffer[0]" instead of "buffer[]", and thus did not trigger a "flexible array member not at end of struct" error from gcc. Move the gpiod_oe field up to fix this, and drop the zero from the array size to prevent future similar bugs.

sub-devices When matching and registering a sub-device from a sub-notifier use the v4l2_device from the root parent notifier. Using the v4l2_dev stored in the sub-notifier itself is incorrect as it might not be set. This can be demonstrated by unbinding and rebinding the adv748x driver and observing that it fails to probe due to the check !v4l2_dev in v4l2_device_register_subdev(). # echo 4-0070 > /sys/bus/i2c/drivers/adv748x/unbind # echo 4-0070 > /sys/bus/i2c/drivers/adv748x/bind adv748x 4-0070: chip found @ 0xe0 revision 2143 adv748x 4-0070: Failed to probe TXA adv748x: probe of 4-0070 failed with error -22 Looking at the commit which adds sub-notifiers to V4L2 it looks like this is the intended behavior of the original commit. With this fix the adv748x can be re-bound and still function properly.

2017-11-30media: v4l2-fwnode: Check subdev count after checking portTomasz Figa
Current implementation of __v4l2_async_notifier_parse_fwnode_endpoints() checks first whether subdev_count >= subdev_max and only then whether the port being parsed matches the given port index. This triggers an error in otherwise valid cases of skipping ports that do not match. Fix this by moving the check below the port index check.

2017-11-30media: rc: partial revert of "media: rc: per-protocol repeat period"Sean Young
Since commit d57ea877af38 ("media: rc: per-protocol repeat period"), most IR protocols have a lower keyup timeout. This causes problems on the ite-cir, which has default IR timeout of 200ms. Since the IR decoders read the trailing space, with a IR timeout of 200ms, the last keydown will have at least a delay of 200ms. This is more than the protocol timeout of e.g. rc-6 (which is 164ms). As a result the last IR will be interpreted as a new keydown event, and we get two keypresses. Revert the protocol timeout to 250ms, except for cec which needs a timeout of 550ms.
