Introduce helper function irq_data_get_affinity_mask() and
irq_get_affinity_mask() to hide implementation details,
so we could move field 'affinity' from struct irq_data into
struct irq_common_data later.

There's no use of gsi_override related logic anymore, so kill code
related to gsi_override.

Hi Sander,
It really cost me some time to understand HVM, PVH, Dom0, PV and
read Xen interrupt related code:( Now I have basic understanding of
related staffs. The patch for previous issue is actually wrong and
I'm working on another fixes for it. I will handle this issue once
getting done

Hi Sander,
Could you please help to test this patch against 3.19-rc3?
I have reworked it based Konrad's suggestions.
Thanks!

Hi all,
This patch should be backported to v3.17, but there are
conflicts. So I will send backported patch to 3.17/3.18 stable tree

Rename __read_msi_msg() as __pci_read_msi_msg() and kill unused
read_msi_msg(). It's a preparation to separate generic MSI code
from PCI core.

Rename __write_msi_msg() as __pci_write_msi_msg() to mark it as PCI
specific. Also define pci_write_msi_msg() as write_msi_msg() for easy
transition.
