Hi All,

As explained in the changelog of patch [2/7], using struct pci_platform_pm_ops
for ACPI is not particularly beneficial, so it is better to get rid of it and
call the functions pointed to by it directly from the PCI core.

However, struct pci_platform_pm_ops is also used by the Intel MID support code,
but it is actually better to call the MID PM function directly from the PCI
core either, which is done in patch [1/7].

After these changes, patch [3/7] removes struct pci_platform_pm_ops and the
rest is just cleanups and some code consolidation on top of that.

Thanks!

I like these a lot.  Not sure exactly where everything is after the
conversation with Ferry.  Let me know if I should be doing anything.

It's mostly OK, the problem was in one of the "tail" patches that was
not rebased properly.

There will be a follow-up series to test for Ferry (later today).

I'm going to take this lot if that's not a problem.  If I need
anything from you, I'll let you know.

I will happily retest likely on Sunday after I return from short holiday 
and report back here.
