| |
Memory for host controller data structures is allocated local to the node to which the controller is associated with. This has been the behaviour since 965cd0e4a5e5 ("x86, PCI, ACPI: Use kmalloc_node() to optimize for performance") where the node local allocation was added without additional context.
Drop the node local allocation as there is no benefit from doing so - the usage of these structures is independent from where the controller is located.
