This series moves code around in order to liberate some
pci and pci-testdev code from x86-only territory. There
are no functional changes, but now x86 unit tests also get
to enjoy asm-generic/io.h and asm-generic/page.h defines.
A couple other non-function changes made are; the value
of PCIDEVADDR_INVALID is now more invalid, and we import
linux-uapi/pci_regs.h, which is necessary for additional
architectures to use lib/pci.
Andrew Jones (11):
asm-generic: add portio accessors to io.h
x86: move io.h to asm
x86: use common portio accessors from io.h
x86: pci.h: remove useless include
x86: mov pci.h to asm
x86: move x86/pci to the common lib
x86: share pci-testdev hdr in common lib
lib/pci: make PCIDEVADDR_INVALID truly invalid
lib: add linux dir for kernel uapi headers

Also throw an '#include "asm-generic/io.h"' at the bottom. Doing
that requires also adding an asm/page.h, and then some changes to
vm.[ch] to integrate with it.

x86 code reinvents io*/out* in a few places. To prepare for a common
pci driver use the common accessors from io.h in pci.c and vmexit.c.
Now we use the correct order (value, port) for out* too.

dev addr 0 is valid, just not for the pci-testdev (since the host
bridge is already there). So, while it's not a problem, let's
"fix" it anyway.

We needed to import some uapi headers, e.g. lib/arm/asm/uapi-psci.h,
and will need some others, e.g. pci_regs.h, in the future. Create a
linux directory for them in lib so that they can be included with
the familiar <linux/header.h> reference.
(Note, x86 has been cheating. lib/x86/pci.c already includes
<linux/pci_regs.h>, which it's been getting away with as its include
paths are less strict than arm's, i.e. it *does* look in /usr/include)
