2021-04-16perf: Cap allocation order at aux_watermarkAlexander Shishkin
Currently, we start allocating AUX pages half the size of the total requested AUX buffer size, ignoring the attr.aux_watermark setting. This, in turn, makes intel_pt driver disregard the watermark also, as it uses page order for its SG (ToPA) configuration. Now, this can be fixed in the intel_pt PMU driver, but seeing as it's the only one currently making use of high order allocations, there is no reason not to fix the allocator instead. This way, any other driver wishing to add this support would not have to worry about this.

2021-04-16mmc: dw_mmc-rockchip: Just set default sample value for legacy modeShawn Lin
.set_ios() is called from .resume() as well. For SDIO device which sets keep-power-in-suspend, nothing should be changed after resuming, as well as sample tuning value, since this value is tuned already. So we should not overwrite it with the default value.

2021-04-16spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single failsQuanyang Wang
The spi controller supports 44-bit address space on AXI in DMA mode, so set dma_addr_t width to 44-bit to avoid using a swiotlb mapping. In addition, if dma_map_single fails, it should return immediately instead of continuing doing the DMA operation which bases on invalid address. This fixes the following crash which occurs in reading a big block from flash: [ 123.633577] zynqmp-qspi ff0f0000.spi: swiotlb buffer is full (sz: 4194304 bytes), total 32768 (slots), used 0 (slots) [ 123.644230] zynqmp-qspi ff0f0000.spi: ERR:rxdma:memory not mapped [ 123.784625] Unable to handle kernel paging request at virtual address 00000000003fffc0 [ 123.792536] Mem abort info: [ 123.795313] ESR = 0x96000145 [ 123.798351] EC = 0x25: DABT (current EL), IL = 32 bits [ 123.803655] SET = 0, FnV = 0 [ 123.806693] EA = 0, S1PTW = 0 [ 123.809818] Data abort info: [ 123.812683] ISV = 0, ISS = 0x00000145 [ 123.816503] CM = 1, WnR = 1 [ 123.819455] user pgtable: 4k pages, 48-bit VAs, pgdp=0000000805047000 [ 123.825887] [00000000003fffc0] pgd=0000000803b45003, p4d=0000000803b45003, pud=0000000000000000 [ 123.834586] Internal error: Oops: 96000145 [#1] PREEMPT SMP Fixes: 1c26372e5aa9 ("spi: spi-zynqmp-gqspi: Update driver to use spi-mem framework") Signed-off-by: Quanyang Wang <quanyang.wang@windriver.com> Link: https://lore.kernel.org/r/20210416004652.2975446-6-quanyang.wang@windriver.com Signed-off-by: Mark Brown <broonie@kernel.org>

2021-04-16spi: spi-zynqmp-gqspi: fix hang issue when suspend/resumeQuanyang Wang
After calling platform_set_drvdata(pdev, xqspi) in probe, the return value of dev_get_drvdata(dev) is a pointer to struct zynqmp_qspi but not struct spi_controller. A wrong structure type passing to the functions spi_controller_suspend/resume will hang the system. And we should check the return value of spi_controller_suspend, if an error is returned, return it to PM subsystem to stop suspend. Also, GQSPI_EN_MASK should be written to GQSPI_EN_OFST to enable the spi controller in zynqmp_qspi_resume since it was disabled in zynqmp_qspi_suspend before.

2021-04-16spi: spi-zynqmp-gqspi: fix clk_enable/disable imbalance issueQuanyang Wang
The clks "pclk" and "ref_clk" are enabled twice during the probe. The first time is in the function zynqmp_qspi_probe and the second time is in zynqmp_qspi_setup_op which is called by devm_spi_register_controller. Then calling zynqmp_qspi_remove (rmmod this module) to disable these clks will trigger a warning as below: [ 309.124604] Unpreparing enabled qspi_ref [ 309.128641] WARNING: CPU: 1 PID: 537 at drivers/clk/clk.c:824 clk_core_unprepare+0x108/0x110 Since pm_runtime works now, clks can be enabled/disabled by calling zynqmp_runtime_suspend/resume. So we don't need to enable these clks explicitly in zynqmp_qspi_setup_op. Remove them to fix this issue. And remove clk enabling/disabling in zynqmp_qspi_resume because there is no spi transfer operation so enabling ref_clk is redundant meanwhile pclk is not disabled for it is shared with other peripherals. Furthermore replace clk_enable/disable with clk_prepare_enable and clk_disable_unprepare in runtime_suspend/resume functions.

2021-04-16bfq/mq-deadline: remove redundant check for passthrough requestLin Feng
Since commit 01e99aeca39796003 'blk-mq: insert passthrough request into hctx->dispatch directly', passthrough request should not appear in IO-scheduler any more, so blk_rq_is_passthrough checking in addon IO schedulers is redundant. (Notes: this patch passes generic IO load test with hdds under SAS controller and hdds under AHCI controller but obviously not covers all. Not sure if passthrough request can still escape into IO scheduler from blk_mq_sched_insert_requests, which is used by blk_mq_flush_plug_list and has lots of indirect callers.)

Commit 01e99aeca39796003 ("blk-mq: insert passthrough request into hctx->dispatch directly") gives high priority to passthrough requests and bypass underlying IO scheduler.

2021-04-16crypto: qat - enable detection of accelerators hangWojciech Ziemba
Enable the detection of hangs by setting watchdog timers (WDTs) on generations that supports that feature. The default timeout value comes from HW specs. WTDs are reset each time an accelerator wins arbitration and is able to send/read a command to/from an accelerator. The value has added significant margin to make sure there are no spurious timeouts. The scope of watchdog is per QAT device. If a timeout is detected, the firmware resets the accelerator and returns a response descriptor with an appropriate error code.

2021-04-16crypto: arm64/aes-ce - deal with oversight in new CTR carry codeArd Biesheuvel
The new carry handling code in the CTR driver can deal with a carry occurring in the 4x/5x parallel code path, by using a computed goto to jump into the carry sequence at the right place as to only apply the carry to a subset of the blocks being processed. If the lower half of the counter wraps and ends up at exactly 0x0, a carry needs to be applied to the counter, but not to the counter values taken for the 4x/5x parallel sequence. In this case, the computed goto skips all register assignments, and branches straight to the jump instruction that gets us back to the fast path. This produces the correct result, but due to the fact that this branch target does not carry the correct BTI annotation, this fails when BTI is enabled. Let's omit the computed goto entirely in this case, and jump straight back to the fast path after applying the carry to the main counter.

2021-04-16x86/platform/uv: Use x2apic enabled bit as set by BIOS to indicate APIC modeMike Travis
BIOS now sets the x2apic enabled bit (and the ACPI table) for extended APIC modes. Use that bit to indicate if extended mode is set.

2021-04-16Drivers: hv: vmbus: Use after free in __vmbus_open()Dan Carpenter
The "open_info" variable is added to the &vmbus_connection.chn_msg_list, but the error handling frees "open_info" without removing it from the list. This will result in a use after free. First remove it from the list, and then free it.

2021-04-16coresight: etm-perf: Fix define build issue when built as moduleMike Leach
CONFIG_CORESIGHT_SOURCE_ETM4X is undefined when built as module, CONFIG_CORESIGHT_SOURCE_ETM4X_MODULE is defined instead. Therefore code in format_attr_contextid_show() not correctly complied when coresight built as module. Use IS_ENABLED(CONFIG_CORESIGHT_SOURCE_ETM4X) to correct this.
