2022-06-09netfs: Fix gcc-12 warning by embedding vfs inode in netfs_i_contextDavid Howells
While randstruct was satisfied with using an open-coded "void *" offset cast for the netfs_i_context <-> inode casting, __builtin_object_size() as used by FORTIFY_SOURCE was not as easily fooled. This was causing the following complaint[1] from gcc v12: In file included from include/linux/string.h:253, from include/linux/ceph/ceph_debug.h:7, from fs/ceph/inode.c:2: In function 'fortify_memset_chk', inlined from 'netfs_i_context_init' at include/linux/netfs.h:326:2, inlined from 'ceph_alloc_inode' at fs/ceph/inode.c:463:2: include/linux/fortify-string.h:242:25: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning] 242 | __write_overflow_field(p_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix this by embedding a struct inode into struct netfs_i_context (which should perhaps be renamed to struct netfs_inode). The struct inode vfs_inode fields are then removed from the 9p, afs, ceph and cifs inode structs and vfs_inode is then simply changed to "netfs.inode" in those filesystems. Further, rename netfs_i_context to netfs_inode, get rid of the netfs_inode() function that converted a netfs_i_context pointer to an inode pointer (that can now be done with &ctx->inode) and rename the netfs_i_context() function to netfs_inode() (which is now a wrapper around container_of()). Most of the changes were done with: perl -p -i -e 's/vfs_inode/netfs.inode/'g \ `git grep -l 'vfs_inode' -- fs/{9p,afs,ceph,cifs}/*.[ch]` Kees suggested doing it with a pair structure[2] and a special declarator to insert that into the network filesystem's inode wrapper[3], but I think it's cleaner to embed it - and then it doesn't matter if struct randomisation reorders things. Dave Chinner suggested using a filesystem-specific VFS_I() function in each filesystem to convert that filesystem's own inode wrapper struct into the VFS inode struct[4]. Version #2: - Fix a couple of missed name changes due to a disabled cifs option. - Rename nfs_i_context to nfs_inode - Use "netfs" instead of "nic" as the member name in per-fs inode wrapper structs.

2022-06-09ata: libata-transport: fix {dma|pio|xfer}_mode sysfs filesSergey Shtylyov
The {dma|pio}_mode sysfs files are incorrectly documented as having a list of the supported DMA/PIO transfer modes, while the corresponding fields of the *struct* ata_device hold the transfer mode IDs, not masks. To match these docs, the {dma|pio}_mode (and even xfer_mode!) sysfs files are handled by the ata_bitfield_name_match() macro which leads to reading such kind of nonsense from them: $ cat /sys/class/ata_device/dev3.0/pio_mode XFER_UDMA_7, XFER_UDMA_6, XFER_UDMA_5, XFER_UDMA_4, XFER_MW_DMA_4, XFER_PIO_6, XFER_PIO_5, XFER_PIO_4, XFER_PIO_3, XFER_PIO_2, XFER_PIO_1, XFER_PIO_0 Using the correct ata_bitfield_name_search() macro fixes that: $ cat /sys/class/ata_device/dev3.0/pio_mode XFER_PIO_4 While fixing the file documentation, somewhat reword the {dma|pio}_mode file doc and add a note about being mostly useful for PATA devices to the xfer_mode file doc...

2022-06-06dt-bindings: Add xen,grant-dma IOMMU description for xen-grant DMA opsOleksandr Tyshchenko
The main purpose of this binding is to communicate Xen specific information using generic IOMMU device tree bindings (which is a good fit here) rather than introducing a custom property. Introduce Xen specific IOMMU for the virtualized device (e.g. virtio) to be used by Xen grant DMA-mapping layer in the subsequent commit. The reference to Xen specific IOMMU node using "iommus" property indicates that Xen grant mappings need to be enabled for the device, and it specifies the ID of the domain where the corresponding backend resides. The domid (domain ID) is used as an argument to the Xen grant mapping APIs. This is needed for the option to restrict memory access using Xen grant mappings to work which primary goal is to enable using virtio devices in Xen guests.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull initial Loongarch architecture code from Arnd Bergmann: "This is the majority of the loongarch architecture code, including the final system call interface and all core functionality. It still misses three sets of peripheral but vital patches to add support for other subsystems, which have yet to pass review: - The drivers/firmware/efi stub for booting from a standard UEFI firmware implementation. Both the original custom boot interface and a draft implementation of the EFI stub did not make it, so it is currently impossible to boot the kernel, until the loongarch specific portions get accepted into the UEFI subsystem - The drivers/irqchip/irq-loongson-*.c drivers are shared with the the MIPS port, but currently lack support for ACPI based booting, which will get merged through the irqchip subsystem. - Similarly, the drivers/pci/controller/pci-loongson.c needs to be modified for ACPI support, which will be merged through the PCI subsystem. While the port cannot actually be used before all the above are merged, having it in 5.19 helps to establish the user space ABI for the libc ports to build on, and to help any treewide changes in the mainline kernel get applied here as well. A gcc-12 based tool chains for build testing is now included in https://mirrors.edge.kernel.org/pub/tools/crosstool/" Original description from Huacai Chen: "LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the set of driver core changes for 5.19-rc1. Lots of tiny driver core changes and cleanups happened this cycle, but the two major things are: - firmware_loader reorganization and additions including the ability to have XZ compressed firmware images and the ability for userspace to initiate the firmware load when it needs to, instead of being always initiated by the kernel. FPGA devices specifically want this ability to have their firmware changed over the lifetime of the system boot, and this allows them to work without having to come up with yet-another-custom-uapi interface for loading firmware for them. - physical location support added to sysfs so that devices that know this information, can tell userspace where they are located in a common way. Some ACPI devices already support this today, and more bus types should support this in the future. Smaller changes include: - driver_override api cleanups and fixes - error path cleanups and fixes - get_abi script fixes - deferred probe timeout changes. It's that last change that I'm the most worried about. It has been reported to cause boot problems for a number of systems, and I have a tested patch series that resolves this issue.

The 'unevaluatedProperties' schema checks is not fully working and doesn't catch some cases where there's a $ref to another schema. A fix is pending, but results in new warnings in examples. The Apple PCIe host schema is missing 'power-domains' in the schema. The example has 3 power domains. However, this is wrong too as actual dts files have a single power domain and Sven confirmed 1 is correct.

2022-06-01dt-bindings: PCI: xilinx-cpm: Fix reg property orderBharat Kumar Gogada
All existing vendor DTSes are using "cpm_slcr" reg followed by "cfg" reg. This order is also suggested by node name which is pcie@fca10000 which suggests that cpm_slcr register should be the first. Driver itself is using devm_platform_ioremap_resource_byname() for both names that's why there is no functional change even on description which are using current order. But still prefer to change order to cover currently used description.

There is also a patch to fix an unexpected decompression strategy change due to a cleanup in the past. All the fixes are quite small. Apart from these, documentation is also updated for a better description of recent new features. In addition, this has some trivial cleanups without actual code logic changes, so I could have a more recent codebase to work on folios and avoiding the PG_error page flag for the next cycle.

It introduces support for controlling the audio DSP on Qualcomm MSM8226, as well as audio and compute DSPs on Qualcomm SC8280XP. It makes it possible to specify the firmware path for Mediatek's remote processors, fixes a double free in the SCP driver and addresses an issue with the SRAM initialization on MT8195.
