Subject: kABI: PCI: loongson: Prevent LS7A MRRS increases
Patch-mainline: never, kabi
References: kabi

Commit 8b3517f88ff2 (PCI: loongson: Prevent LS7A MRRS increases) added a
bit to struct pci_host_bridge. This changed the layout of the structure
and the kABI checker complains.

Move the new bit to the end of the bitfield as there is a hole. Note the
order and the hole is the same on both BE and LE. And protect the new
member by the usual __GENKSYMS__ protection.
