[PATCH v2 0/4] PCI: Rework pci_scan_slot() and isolated PCI functions

[Niklas Schnelle <schnelle@linux.ibm.com>]

Hi Bjorn, Hi Jan,

In an earlier version[0], I sought to apply the existing jailhouse special case
for isolated PCI functions to s390. As Bjorn noted in[1] there appears to be
some potential for cleaning things up and removing duplication though.

This series attempts to do this cleanup (Patches 1 and 2) followed by enabling
isolated PCI functions for s390 (Patches 3 and 4). If need be I can of course
split the cleanup off but for now I kept it as one as that's what I have
been testing.

Thanks,
Niklas
