[PATCH v4 1/1] dmaengine: dw: Select only supported masters for ACPI devices

by Andy Shevchenko

From: Serge Semin <fancer.lancer(a)gmail.com> The recently submitted fix-commit revealed a problem in the iDMA 32-bit platform code. Even though the controller supported only a single master the dw_dma_acpi_filter() method hard-coded two master interfaces with IDs 0 and 1. As a result the sanity check implemented in the commit b336268dde75 ("dmaengine: dw: Add peripheral bus width verification") got incorrect interface data width and thus prevented the client drivers from configuring the DMA-channel with the EINVAL error returned. E.g., the next error was printed for the PXA2xx SPI controller driver trying to configure the requested channels: > [ 164.525604] pxa2xx_spi_pci 0000:00:07.1: DMA slave config failed > [ 164.536105] pxa2xx_spi_pci 0000:00:07.1: failed to get DMA TX descriptor > [ 164.543213] spidev spi-SPT0001:00: SPI transfer failed: -16 The problem would have been spotted much earlier if the iDMA 32-bit controller supported more than one master interfaces. But since it supports just a single master and the iDMA 32-bit specific code just ignores the master IDs in the CTLLO preparation method, the issue has been gone unnoticed so far. Fix the problem by specifying the default master ID for both memory and peripheral devices in the driver data. Thus the issue noticed for the iDMA 32-bit controllers will be eliminated and the ACPI-probed DW DMA controllers will be configured with the correct master ID by default.

This is a problem for s390x KVM, which explicitly remaps all PMD-mapped THPs to be PTE-mapped in s390_enable_sie()->thp_split_mm(), before starting the VM. For example, starting a VM backed on a file system with large folios supported makes the VM crash when the VM tries accessing such a mapping using KVM. Is it also a problem when the HW disabled THP using TRANSPARENT_HUGEPAGE_UNSUPPORTED? At least on x86 this would be the case without X86_FEATURE_PSE. In the future, we might be able to do better on s390x and only disallow PMD mappings -- what s390x and likely TRANSPARENT_HUGEPAGE_UNSUPPORTED really wants. For now, fix it by essentially performing the same check as would be done in __thp_vma_allowable_orders() or in shmem code, where this works as expected, and disallow PMD mappings, making us fallback to PTE mappings.

[PATCH v2] arm64: dts: mediatek: mt8186-corsola-voltorb: Merge speaker codec nodes

by Chen-Yu Tsai

The Voltorb device uses a speaker codec different from the original Corsola device. When the Voltorb device tree was first added, the new codec was added as a separate node when it should have just replaced the existing one. Merge the two nodes. The only differences are the compatible string and the GPIO line property name. This keeps the device node path for the speaker codec the same across the MT8186 Chromebook line. Also rename the related labels and node names from having rt1019p to speaker codec. Cc: <stable(a)vger.kernel.org> # v6.11+ Signed-off-by: Chen-Yu Tsai <wenst(a)chromium.org> --- This is technically not a fix, but having the same device tree structure in stable kernels would be more consistent for consumers of the device tree. Hence the request for a stable backport.

During testing, it was found that we can get PMD mappings in processes where THP (and more precisely, PMD mappings) are supposed to be disabled. While it works as expected for anon+shmem, the pagecache is the problematic bit. For s390 KVM this currently means that a VM backed by a file located on filesystem with large folio support can crash when KVM tries accessing the problematic page, because the readahead logic might decide to use a PMD-sized THP and faulting it into the page tables will install a PMD mapping, something that s390 KVM cannot tolerate. This might also be a problem with HW that does not support PMD mappings, but I did not try reproducing it. Fix it by respecting the ways to disable THPs when deciding whether we can install a PMD mapping. khugepaged should already be taking care of not collapsing if THPs are effectively disabled for the hw/process/vma. This patch (of 2): Add vma_thp_disabled() and thp_disabled_by_hw() helpers to be shared by shmem_allowable_huge_orders() and __thp_vma_allowable_orders().
