2020-09-02ARM: dts: exynos: Correct S3C RTC bindings in Tiny4412Krzysztof Kozlowski
The S3C RTC requires 32768 Hz clock as input which is provided by PMIC. However the PMIC is not described in DTS at all so at least add a workaround to model its clock with fixed-clock. This fixes S3C RTC and silences dtbs_check warnings like: arch/arm/boot/dts/exynos4412-tiny4412.dt.yaml: rtc@10070000: clocks: [[7, 346]] is too short arch/arm/boot/dts/exynos4412-tiny4412.dt.yaml: rtc@10070000: clock-names: ['rtc'] is too short Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200830135200.24304-32-krzk@kernel.org

2020-09-02ARM: dts: exynos: Override thermal by label in Exynos4412 OdroidsKrzysztof Kozlowski
Using full paths to extend or override a device tree node is error prone since if there was a typo error, a new node will be created instead of extending the node as it was desired. This will lead to run-time errors that could be hard to detect. A mistyped label on the other hand, will cause a dtc compile error (during build time).

2020-08-16parisc: fix PMD pages allocation by restoring pmd_alloc_one()Mike Rapoport
Commit 1355c31eeb7e ("asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()") converted parisc to use generic version of pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for PMD. Restore the original version of pmd_alloc_one() for parisc, just use GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and memset.

2020-08-15io_uring: short circuit -EAGAIN for blocking read attemptJens Axboe
One case was missed in the short IO retry handling, and that's hitting -EAGAIN on a blocking attempt read (eg from io-wq context). This is a problem on sockets that are marked as non-blocking when created, they don't carry any REQ_F_NOWAIT information to help us terminate them instead of perpetually retrying. Fixes: 227c0c9673d8 ("io_uring: internally retry short reads") Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-08-15io_uring: sanitize double poll handlingJens Axboe
There's a bit of confusion on the matching pairs of poll vs double poll, depending on if the request is a pure poll (IORING_OP_POLL_ADD) or poll driven retry. Add io_poll_get_double() that returns the double poll waitqueue, if any, and io_poll_get_single() that returns the original poll waitqueue. With that, remove the argument to io_poll_remove_double(). Finally ensure that wait->private is cleared once the double poll handler has run, so that remove knows it's already been seen.
