Expect arguments, blk_mq_put_driver_tag_hctx() and blk_mq_put_driver_tag() is same. We can just use argument 'request' to put tag by blk_mq_put_driver_tag(). Then we can remove the unused blk_mq_put_driver_tag_hctx(). Signed-off-by:

Pull io_uring fixes and improvements from Jens Axboe: "The first five in this series are heavily inspired by the work Al did on the aio side to fix the races there. The last two re-introduce a feature that was in io_uring before it got merged, but which I pulled since we didn't have a good way to have BVEC iters that already have a stable reference. These aren't necessarily related to block, it's just how io_uring pins fixed buffers" * tag 'io_uring-20190323' of git://git.kernel.dk/linux-block: block: add BIO_NO_PAGE_REF flag iov_iter: add ITER_BVEC_FLAG_NO_REF flag io_uring: mark me as the maintainer io_uring: retry bulk slab allocs as single allocs io_uring: fix poll races io_uring: fix fget/fput handling io_uring: add prepped flag io_uring: make io_read/write return an integer io_uring: use regular request ref counts

Pull powerpc fixes from Michael Ellerman: "One fix for a boot failure on 32-bit, introduced during the merge window. A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing the wall clock across the Y2038 boundary could cause CLOCK_MONOTONIC to jump forward and backward. Our spectre_v2 reporting was a bit confusing due to a bug I introduced. On some systems it was reporting that the count cache was disabled and also that we were flushing the count cache on context switch. Only the former is true, and given that the count cache is disabled it doesn't make any sense to flush it. No one reported it, so presumably the presence of any mitigation is all people check for. Finally a small build fix for zsmalloc on 32-bit.

If a 32 bit allocation request is too big to possibly succeed, it early exits with a failure and then should never update max32_alloc_ size. This patch fixes current code, now the size is only updated if the slow path failed while walking the tree.

Setting max_blk_count to 1 here was causing the mmc block layer to always use the MMC_READ_SINGLE_BLOCK command here, which the driver does not DMA-accelerate. Drop the max_blk_ settings here. The mmc host defaults suffice, along with the max_segs and max_seg_size settings, which I have now documented in more detail. Now each MMC command reads 4 512-byte blocks, using DMA instead of PIO. On my SD card, this increases read performance (measured with dd) from 167kb/sec to 4.6mb/sec.

After commit 6d5cd068 ("mmc: sdhci: use WP GPIO in sdhci_check_ro()") and commit 39ee32ce ("mmc: sdhci-omap: drop ->get_ro() implementation"), sdhci-omap relied on SDHCI_PRESENT_STATE to check if the card is read-only, if wp-gpios is not populated in device tree. However SDHCI_PRESENT_STATE in sdhci-omap does not have correct read-only state. sdhci-omap can be used by platforms with both micro SD slot and standard SD slot with physical write protect pin (using GPIO). Set caps2 to MMC_CAP2_NO_WRITE_PROTECT based on if wp-gpios property is populated or not. This fix is required since existing device-tree node doesn't have "disable-wp" property and to preserve old-dt compatibility.

When I updated the spectre_v2 reporting to handle software count cache flush I got the logic wrong when there's no software count cache enabled at all. The result is that on systems with the software count cache flush disabled we print: Mitigation: Indirect branch cache disabled, Software count cache flush Which correctly indicates that the count cache is disabled, but incorrectly says the software count cache flush is enabled. The root of the problem is that we are trying to handle all combinations of options. But we know now that we only expect to see the software count cache flush enabled if the other options are false. So split the two cases, which simplifies the logic and fixes the bug. We were also missing a space before "(hardware accelerated)". The result is we see one of: Mitigation: Indirect branch serialisation (kernel only) Mitigation: Indirect branch cache disabled Mitigation: Software count cache flush Mitigation: Software count cache flush (hardware accelerated) Fixes: ee13cb24 ("powerpc/64s: Add support for software count cache flush") Cc: stable@vger.kernel.org # v4.19+ Signed-off-by:

MIXER on Exynos5 SoCs uses different synchronisation method than Exynos4 to update internal state (shadow registers). Apparently the driver implements it incorrectly. The rule should be as follows: - do not request updating registers until previous request was finished, ie. MXR_CFG_LAYER_UPDATE_COUNT must be 0. - before setting registers synchronisation on VSYNC should be turned off, ie. MXR_STATUS_SYNC_ENABLE should be reset, - after finishing MXR_STATUS_SYNC_ENABLE should be set again. The patch hopefully implements it correctly.
