[PATCHv2 RFC (repost) 00/16] pci: use generic pci_iomap on allarchitectures

[Michael S. Tsirkin]

This reposting combines the latest version of the patches.
As this is just a repost, separate versions was already sent to
maintainers, I cut down the To list to just lkml and linux-arch.

This patchset has been on linux-next for several weeks now.
I intend to send pull request to Linus come 3.3 merge window:
They touch a lot of arches and have interdependencies, so merging
separately seems to make sense.

As Jesse Barnes noted: the PCI changes look nice (pulling
all that duplicated code out looks good), though it would be good to
get a few more arch maintainer acks/tested-bys for this.

The patchset is available from my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git linux-next
or from linux-next.

Many architectures don't want to pull in iomap.c,
so they ended up duplicating pci_iomap from that file.
That function isn't trivial, and we are going to modify it
https://lkml.org/lkml/2011/11/14/183
so the duplication hurts.

This reduces the scope of the problem significantly,
by moving pci_iomap to a separate file and
referencing that from all architectures.

Tested on x86, build tested on alpha, mips64 and powerpc64.
