From an allmodconfig build, I see two more things that could be addressed first:

drivers/pci/probe.c: In function 'pci_scan_bridge_extend':
drivers/pci/probe.c:1298:44: error: implicit declaration of function

I think you accidentally dropped the asm/pci.h header, so adding that one back
should make it build again.

Not sure what the best fix is for this, maybe the contents of asm/asm.h could
just be hidden in an "#idef __ASSEMBLER__" check. This can be a follow-up
patch when the branch is merged.
