Yep, that's exactly the purpose of my patches.

Yep. Though, I don't bother with exporting symbols that neither
ahci (PCI driver) nor platform driver need. Later we might export
some more for mv/acard-ahci...

OK. So in these series:

- I kept PCI driver in ahci.c (built as ahci.ko);
- Moved generic code into libahci.{c,h} (built as libahci.ko)

Also in these series:

- Rebased on top of linux-next (the patches also apply onto the
current Linus' git tree, fwiw).
- Dropped sparse fixes patch, as the issue appears to be already
fixed in linux-next.
- Addressed Sergei's comments on ahci_platform driver.
