2023-08-22blk-mq: prealloc tags when increase tagset nr_hw_queuesChengming Zhou
Just like blk_mq_alloc_tag_set(), it's better to prepare all tags before using to map to queue ctxs in blk_mq_map_swqueue(), which now have to consider empty set->tags[]. The good point is that we can fallback easily if increasing nr_hw_queues fail, instead of just mapping to hctx[0] when fail in blk_mq_map_swqueue(). And the fallback path already has tags free & clean handling, so all is good.

2023-08-22blk-mq: fix tags leak when shrink nr_hw_queuesChengming Zhou
Although we don't need to realloc set->tags[] when shrink nr_hw_queues, we need to free them. Or these tags will be leaked. How to reproduce: 1. mount -t configfs configfs /mnt 2. modprobe null_blk nr_devices=0 submit_queues=8 3. mkdir /mnt/nullb/nullb0 4. echo 1 > /mnt/nullb/nullb0/power 5. echo 4 > /mnt/nullb/nullb0/submit_queues 6. rmdir /mnt/nullb/nullb0 In step 4, will alloc 9 tags (8 submit queues and 1 poll queue), then in step 5, new_nr_hw_queues = 5 (4 submit queues and 1 poll queue). At last in step 6, only these 5 tags are freed, the other 4 tags leaked.

Move user SDMA system memory page-pinning code from user_sdma.c to pin_system.c. Put declarations for non-static functions in pinning.h. System memory pinning is necessary for processing user SDMA requests but actual steps are invisible to user SDMA request-processing code. Moving system memory pinning code for user SDMA to its own file makes this distinction apparent. These changes have no effect on userspace.

2023-08-22RDMA/efa: Fix wrong resources deallocation orderYonatan Nachum
When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If the device fails, the object isn't fully destroyed so the user/IB core can try to destroy the object again which will lead to underflow when trying to decrease an already zeroed refcount. Deallocate resources in reverse order of allocating them to safely free them.

2023-08-22phy: exynos5-usbdrd: Add Exynos850 supportSam Protsenko
Implement Exynos850 USB 2.0 DRD PHY controller support. Exynos850 has quite a different PHY controller than Exynos5 compatible controllers, but it's still possible to implement it on top of existing exynos5-usbdrd driver infrastructure. Only UTMI+ (USB 2.0) PHY interface is implemented, as Exynos850 doesn't support USB 3.0. Only two clocks are used for this controller: - phy: bus clock, used for PHY registers access - ref: PHY reference clock (OSCCLK) Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20230819031731.22618-7-semen.protsenko@linaro.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
2023-08-22phy: exynos5-usbdrd: Add 26MHz ref clk supportSam Protsenko
Modern Exynos chips (like Exynos850) might have 26 MHz OSCCLK external clock, which is also used as a PHY reference clock. For some USB PHY controllers (e.g USB DRD PHY block on Exynos850) there is no need to set the refclk frequency at all (and corresponding bits in CLKRSTCTRL[7:5] are marked RESERVED), so that value won't be set in the driver. But even in that case, 26 MHz support still has to be added, otherwise exynos5_rate_to_clk() fails, which leads in turn to probe error. Add the correct value for 26MHz refclk to make it possible to add support for new Exynos USB DRD PHY controllers.

Provide a way to use different PHY ops for different chips. Right now all chips are using exynos5_usbdrd_phy_ops, but it won't always be the case. For example, Exynos850 has very different USB PHY block, so there will be another PHY ops implementation for that chip. No functional change.

During rebase of qcom-qmp-combo series a call to devm_clk_bulk_get_all() got moved by git from qmp_combo_parse_dt_legacy() to phy_dp_clks_register(). This doesn't have any serious effect, since the clocks will be set in both legacy and non-legacy paths. However let's move it back to place anyway, to prevent the driver from fetching clocks twice.
