Bjorn, This is a small collection of miscellaneous updates that originated in the PCI/TSM work, but are suitable to go ahead in v6.17. It is a documentation update and a new pci_bus_find_emul_domain_nr() helper. First, the PCI/TSM work (Trusted Execution Environment Security Manager (PCI device assignment for confidential guests)) wants to add some additional PCI host bridge sysfs attributes. In preparation for that, document what is already there. Next, the PCI/TSM effort proposes samples/devsec/ as a reference and test implementation of all the TSM infrastructure. It is implemented via host bridge emulation and aims to be cross-architecture compatible. It stumbled over the current state of PCI domain number emulation being arch and driver specific. Remove some of that differentiation and unify the existing x86 host bridge emulators (hyper-v and vmd) on a common pci_bus_find_emul_domain_nr() helper.
