bd0b9ac405 genirq: Remove irq argument from irq flow handlers
Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

280510f106 PCI/MSI: Rename mask/unmask_msi_irq treewide
The PCI/MSI irq chip callbacks mask/unmask_msi_irq have been renamed
to pci_msi_mask/unmask_irq to mark them PCI specific. Rename all usage
sites. The conversion helper functions are kept around to avoid
conflicts in next and will be removed after merging into mainline.

Coccinelle assisted conversion. No functional change.

8d2af85e87 ARM: iop13xx: fix msi support with sparse IRQ
patch 37ebbcff78 ("arm: iop13xx: Use sparse irqs for MSI") moved
iop13xx over to sparse IRQ support, but this broke the build for the
msi.c file, which now has to include mach/irqs.h itself.

37ebbcff78 arm: iop13xx: Use sparse irqs for MSI
No need for a private allocator. The core code handles it
already. 

Allocate the non MSI irqs right at boot time via machine_desc->nr_irqs
and let the sparse core handle the MSI space.

d73d801177 [ARM] 4383/1: iop: fix usage of '__init' and 'inline' in iop files
WARNING: arch/arm/mach-iop13xx/built-in.o - Section mismatch: reference to
.init.text:iop13xx_pcie_map_irq from .text between 'iop13xx_pci_setup' (at
offset 0x7fc) and 'iop13xx_map_pci_memory'

While fixing this warning I also recalled Adrian Bunk's recommendation to
not use inline in .c files, as 'iop13xx_map_pci_memory' is needlessly
inlined.

Removing 'inline' uncovered some dead code so that is cleaned up as well.
