mmc: core: Add SD card quirk for broken discard

2022-10-30T08:41:19Z

commit 07d2872bf4c864eb83d034263c155746a2fb7a3b upstream. Some SD-cards from Sandisk that are SDA-6.0 compliant reports they supports discard, while they actually don't. This might cause mk2fs to fail while trying to format the card and revert it to a read-only mode. To fix this problem, let's add a card quirk (MMC_QUIRK_BROKEN_SD_DISCARD) to indicate that we shall fall-back to use the legacy erase command instead.

kvm: Add support for arch compat vm ioctls

2022-10-30T08:41:15Z

commit ed51862f2f57cbce6fed2d4278cfe70a490899fd upstream. We will introduce the first architecture specific compat vm ioctl in the next patch. Add all necessary boilerplate to allow architectures to override compat vm ioctls when necessary.

io_uring/af_unix: defer registered files gc to io_uring release

2022-10-26T11:25:55Z

[ upstream commit 0091bfc81741b8d3aeb3b7ab8636f911b2de6e80 ] Instead of putting io_uring's registered files in unix_gc() we want it to be done by io_uring itself. The trick here is to consider io_uring registered files for cycle detection but not actually putting them down. Because io_uring can't register other ring instances, this will remove all refs to the ring file triggering the ->release path and clean up with io_ring_ctx_free().

iommu/iova: Fix module config properly

2022-10-26T11:25:42Z

[ Upstream commit 4f58330fcc8482aa90674e1f40f601e82f18ed4a ] IOMMU_IOVA is intended to be an optional library for users to select as and when they desire. Since it can be a module now, this means that built-in code which has chosen not to select it should not fail to link if it happens to have selected as a module by someone else. Replace IS_ENABLED() with IS_REACHABLE() to do the right thing.

serial: 8250: Toggle IER bits on only after irq has been set up

2022-10-26T11:25:36Z

[ Upstream commit 039d4926379b1d1c17b51cf21c500a5eed86899e ] Invoking TIOCVHANGUP on 8250_mid port on Ice Lake-D and then reopening the port triggers these faults during serial8250_do_startup(): DMAR: DRHD: handling fault status reg 3 DMAR: [DMA Write NO_PASID] Request device [00:1a.0] fault addr 0x0 [fault reason 0x05] PTE Write access is not set If the IRQ hasn't been set up yet, the UART will have zeroes in its MSI address/data registers. Disabling the IRQ at the interrupt controller won't stop the UART from performing a DMA write to the address programmed in its MSI address register (zero) when it wants to signal an interrupt. The UARTs (in Ice Lake-D) implement PCI 2.1 style MSI without masking capability, so there is no way to mask the interrupt at the source PCI function level, except disabling the MSI capability entirely, but that would cause it to fall back to INTx# assertion, and the PCI specification prohibits disabling the MSI capability as a way to mask a function's interrupt service request. The MSI address register is zeroed by the hangup as the irq is freed. The interrupt is signalled during serial8250_do_startup() performing a THRE test that temporarily toggles THRI in IER. The THRE test currently occurs before UART's irq (and MSI address) is properly set up. Refactor serial8250_do_startup() such that irq is set up before the THRE test. The current irq setup code is intermixed with the timer setup code. As THRE test must be performed prior to the timer setup, extract it into own function and call it only after the THRE test. The ->setup_timer() needs to be part of the struct uart_8250_ops in order to not create circular dependency between 8250 and 8250_base modules.

ata: fix ata_id_has_dipm()

2022-10-26T11:25:35Z

[ Upstream commit 630624cb1b5826d753ac8e01a0e42de43d66dedf ] ACS-5 section 7.13.6.36 Word 78: Serial ATA features supported states that: If word 76 is not 0000h or FFFFh, word 78 reports the features supported by the device. If this word is not supported, the word shall be cleared to zero. (This text also exists in really old ACS standards, e.g. ACS-3.) The problem with ata_id_has_dipm() is that the while it performs a check against 0 and 0xffff, it performs the check against ATA_ID_FEATURE_SUPP (word 78), the same word where the feature bit is stored. Fix this by performing the check against ATA_ID_SATA_CAPABILITY (word 76), like required by the spec. The feature bit check itself is of course still performed against ATA_ID_FEATURE_SUPP (word 78). Additionally, move the macro to the other ATA_ID_FEATURE_SUPP macros (which already have this check), thus making it more likely that the next ATA_ID_FEATURE_SUPP macro that is added will include this check.
