[PATCH V4 14/23] x86, ia64: Include acpi_pci_{add|remove}_bus to the default pcibios_{add|remove}_bus implementation.

linux-acpi, linux-pci, lkml
Subsystem:
pci subsystem, the rest, x86 architecture (32-bit and 64-bit) · Maintainers:

x86 and ia64 are the only arches that implement pcibios_{add|remove}_bus hooks
and implement them in the same way. Moreover ARM64 is going to do the same.
So it seems that acpi_pci_{add|remove}_bus is generic enough to be default
option for pcibios_{add|remove}_bus hooks. Also, it is always safe to run
acpi_pci_{add|remove}_bus as they have empty stubs for !ACPI case and
return if ACPI has been switched off in run time.
After all we can remove x86 and ia64 pcibios_{add|remove}_bus
implementation.
