If a PCI bridge (or PCIe port) that is runtime-suspended gets an ACPI hotplug notification, such as a bus check, it has to be resumed before re-scanning the devices below it, or those devices will not be accessible and will be treated as hot-removed. Make that happen and let the bridge suspend again after the bus below it has been re-scanned. This is a replacement for commit 16468c78 ("ACPI / hotplug / PCI: Runtime resume bridge before rescan") that has been reverted, because it introduced a system resume regression (due to missing bridge->pci_dev checks that are necessary in case the notification is targeted at the host bridge) and it is necessary for the code added by commit 006d44e4 ("PCI: Add runtime PM support for PCIe ports") to work as expected.

The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.

Future SoCs will require different values in cfg0/1, so the two values are stored separately in the per-SoC data structures. For reference, the values are all documented in NV bug 1771116 comment 20.

pcibios_min_mem only exists on 32-bit ARM, so using it in pci-tegra.c prevents the driver from being used on other arches. In __pci_assign_resource(), we clip the available area based on PCIBIOS_MIN_MEM. On 32-bit ARM, this is pcibios_min_mem, with a default value of 0x01000000. For Tegra, we discover the space available for PCI resource allocation from the device tree, and the lowest address that will ever be available is 0x12000000 (on Tegra124). The Tegra windows are always higher than the default pcibios_min_mem, so the __pci_assign_resource() has no effect, so there's no need to adjust pcibios_min_mem here.

Set the affinity_mask in the PCI device before allocating vectors so that the affinity can be propagated through the MSI descriptor structures to the core IRQ code. To facilitate this, new __pci_enable_msi_range() and __pci_enable_msix_range() helpers are factored out of their not prefixed variants which assigning the new IRQ affinity mask in the PCI device so that the low-level interrupt code can perform the interrupt affinity assignment and do node-local allocations. A new PCI_IRQ_NOAFFINITY flag is added to pci_alloc_irq_vectors() so that this function can also be used by drivers that don't wish to use the automatic affinity assignment.

Add a function to allocate and free a range of interrupt vectors, using MSI-X, MSI or legacy vectors (in that order) based on the capabilities of the underlying device and PCIe complex. Additionally a new helper is provided to get the Linux IRQ number for given device-relative vector so that the drivers don't need to allocate their own arrays to keep track of the vectors for the multi vector MSI-X case.

The "entries" argument isn't needed if the list of entries does not contain any holes. Make it optional so that we can avoid the need to allocate a msix_entry structure for this (common) case.
