Now that pci_parse_request_of_pci_ranges() callers just setup pci_host_bridge.windows and dma_ranges directly and don't need the bus range returned, we can just initialize them when allocating the pci_host_bridge struct. With this, pci_parse_request_of_pci_ranges() becomes a static function.

The rcar-gen2 host driver still uses the old Arm PCI setup function pci_common_init_dev(). Let's update it to use the modern devm_pci_alloc_host_bridge(), pci_parse_request_of_pci_ranges() and pci_host_probe() functions.

The pci-rcar-gen2 controller requires only a prefetchable memory region, and the error prevents using pci_parse_request_of_pci_ranges() for it. Let's reduce this to just a warning message so this function can be used for pci-rcar-gen2.

There's no need to create a temporary resource list and then splice it to struct pci_host_bridge.windows list. Just use pci_host_bridge.windows directly.

There's no need to store the bus number or range resource as the driver only needs the bus number which is already in the pci_host_bridge. For endpoint mode, the bus number is always 0.

Most host drivers only parse the DT bus range to set the root bus number in pci_host_bridge.busnr. The ones that don't set busnr are buggy in that they ignore what's in DT. Let's set busnr in pci_scan_root_bus_bridge() where we already check for the bus resource and remove setting it in host drivers.

The work to do that is not yet complete, so probably won't make it in for v5.8, but we are looking to get this simple patch in for v5.8 since we have it ready. We are planning on the rest of the work for extending the SafeSetID LSM being merged during the v5.9 merge window" * tag 'LSM-add-setgid-hook-5.8-author-fix' of git://github.com/micah-morton/linux: security: Add LSM hooks to set*gid syscalls

Thomas Cedeno authored
The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot.

Pull btrfs updates from David Sterba: "This reverts the direct io port to iomap infrastructure of btrfs merged in the first pull request. We found problems in invalidate page that don't seem to be fixable as regressions or without changing iomap code that would not affect other filesystems. There are four reverts in total, but three of them are followup cleanups needed to revert a43a67a2 cleanly. The result is the buffer head based implementation of direct io. Reverts are not great, but under current circumstances I don't see better options" * tag 'for-5.8-part2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: Revert "btrfs: switch to iomap_dio_rw() for dio" Revert "fs: remove dio_end_io()" Revert "btrfs: remove BTRFS_INODE_READDIO_NEED_LOCK" Revert "btrfs: split btrfs_direct_IO to read and write part"
