[PATCH v2 00/22] Use MSI chip framework to configure MSI/MSI-X in all platforms

[Yijing Wang]

This series is based Bjorn's pci/msi branch
git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git pci/msi

Currently, there are a lot of weak arch functions in MSI code.
Thierry Reding Introduced MSI chip framework to configure MSI/MSI-X in arm.
This series use MSI chip framework to refactor MSI code across all platforms
to eliminate weak arch functions. Then all MSI irqs will be managed in a
unified framework. Because this series changed a lot of ARCH MSI code,
so tests in the platforms which MSI code modified are warmly welcomed!

v1->v2:
Add a patch to make s390 MSI code build happy between patch "x86/xen/MSI: E.."
and "s390/MSI: Use MSI..". Fix several typo problems found by Lucas.

RFC->v1:
Updated "[patch 4/21] x86/xen/MSI: Eliminate...", export msi_chip instead
of #ifdef to fix MSI bug in xen running in x86.
Rename arch_get_match_msi_chip() to arch_find_msi_chip().
Drop use struct device as the msi_chip argument, we will do that
later in another patchset.

Yijing Wang (22):
PCI/MSI: Clean up struct msi_chip argument
PCI/MSI: Remove useless bus->msi assignment
MSI: Remove the redundant irq_set_chip_data()
x86/xen/MSI: Eliminate arch_msix_mask_irq() and arch_msi_mask_irq()
s390/MSI: Use __msi_mask_irq() instead of default_msi_mask_irq()
PCI/MSI: Introduce weak arch_find_msi_chip() to find MSI chip
PCI/MSI: Refactor struct msi_chip to make it become more common
x86/MSI: Use MSI chip framework to configure MSI/MSI-X irq
