Some instances of pci_ops initialization rely on the read/write members'
location in the struct. This is fragile and may break when adding new
members to the beginning of the struct.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

Pull irq domain updates from Thomas Gleixner:
"The real interesting irq updates:
- Support for hierarchical irq domains:
For complex interrupt routing scenarios where more than one
interrupt related chip is involved we had no proper representation
in the generic interrupt infrastructure so far. That made people
implement rather ugly constructs in their nested irq chip
implementations. The main offenders are x86 and arm/gic.
To distangle that mess we have now hierarchical irqdomains which
seperate the various interrupt chips and connect them via the
hierarchical domains. That keeps the domain specific details
internal to the particular hierarchy level and removes the
criss/cross referencing of chip internals. The resulting hierarchy
for a complex x86 system will look like this:
vector mapped: 74
msi-0 mapped: 2
dmar-ir-1 mapped: 69
ioapic-1 mapped: 4
ioapic-0 mapped: 20
pci-msi-2 mapped: 45
dmar-ir-0 mapped: 3
ioapic-2 mapped: 1
pci-msi-1 mapped: 2
htirq mapped: 0
Neither ioapic nor pci-msi know about the dmar interrupt remapping
between themself and the vector domain. If interrupt remapping is
disabled ioapic and pci-msi become direct childs of the vector
domain.
In hindsight we should have done that years ago, but in hindsight
we always know better :)
- Support for generic MSI interrupt domain handling
We have more and more non PCI related MSI interrupts, so providing
a generic infrastructure for this is better than having all
affected architectures implementing their own private hacks.
- Support for PCI-MSI interrupt domain handling, based on the generic
MSI support.
This part carries the pci/msi branch from Bjorn Helgaas pci tree to
avoid a massive conflict. The PCI/MSI parts are acked by Bjorn.
I have two more branches on top of this. The full conversion of x86
to hierarchical domains and a partial conversion of arm/gic"
