Hi,
currently there is a wild mixture of isl, isil, and intersil

possible to change

Patch is only compile tested. Will really help

Hi Bjorn,
I resent a series with updates that fix kbuild robot errors.
Hopefully, the rebase for pci/msi would not cause

I'm confused why storing 0x0102 would be a problem. I think gcc does that even
on other cpus.
More atomicity can't hurt, can it?

I must defer to James for any additional details on why PARISC systems
don't provide atomicity
How many PARISC systems do we have that actually do real work on Linux?

There are no archs that override arch_msi_check_device()
hook. Remove it as it is completely redundant.
If an arch would need to check MSI/MSI-X possibility for a
device it should make it within arch_setup_msi_irqs() hook.

Moving MSI checks from arch_msi_check_device() function to
arch_setup_msi_irqs() function makes code more compact and
allows removing unnecessary hook arch_msi_check_device()
from generic MSI code.

Hello,
This is a cleanup effort to get rid of arch_msi_check_device() function.
I am sending v2 series, since kbuild for v1 reports compile errors on
ppc4xx and Armada 370. Still, I have not checked the fixes on these
platforms.
Changes since v1:
- patch 1: 'pdev' undeclared compile error

I'd be very surprised if this problem didn't exist on all alignment
requiring architectures, like PPC and Sparc as well. I know it would be
very convenient if all the
