Greg - can you revert

    pcmcia: add a new resource manager for non ISA systems
    
    On a pure PCI platform we don't actually need all the complexity of
    the rsrc_nonstatic manager, in fact we can just work directly with
    the pci allocators and avoid all the complexity (and code bloat).

and the one on top of it

commit d885d4f3728f386034bb2f7a61b7f2054c49b2d4

    pcmcia: add missing include for new pci resource handler
    
    The recently added rsrc_pci.c file calls pci_bus_alloc_resource without
    including the header file that declares it, and that sometimes causes
    a build warning on ARM:
    
    drivers/pcmcia/rsrc_pci.c: In function 'find_io_region':
    drivers/pcmcia/rsrc_pci.c:40:2: error: implicit declaration of function 'pci_bus_alloc_resource' [-Werror=implicit-function-declaration]
    
    This adds the missing include statement.

as it seems there is a regression in there for some configuration of I/O
based devices. I'll take a look at it over the next couple of kernel
releases and see what is up then resubmit it with fixes.
