Commit 78013eaadf69 ("x86: remove the IOMMU table infrastructure")
refactored the generic swiotlb/swiotlb-xen setup into pci-dma.c, but
misses to adjust MAINTAINERS.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about
broken references.
Update the SWIOTLB SUBSYSTEM to contain the architecture-independent
pieces for swiotlb, but leave the small architecture-dependent pieces to
the architecture maintainers.
Further, update the XEN SWIOTLB SUBSYSTEM to include all swiotlb-xen
headers and replace the pattern in drivers with the specific one file that
matches this pattern.

v1 -> v2:
addressed Christoph's comment, removed arch/*/kernel/pci-swiotlb.c
added Juergen's ack
Christoph, please pick this minor non-urgent clean-up patch for swiotlb.

Sure, great idea. I just sent a patch v3 doing so:

Sorry for coming up with this only now, but what about just dropping
the separate swiotlb entry entirely, and just add include/linux/swiotlb.h
to the dma-mapping entry?
