Subject[RFC PATCH 0/9] Introduce irq_remap_ops to x86
Date
Hi,

in order to implement interrupt remapping using the AMD IOMMU I did some
refactoring of the current Intel-specific interrupt remapping code. The
result is posted for comments in this patch-set.

The patch-set basically removes the Intel-specific calls from the X86
apic and io-apic code and replaces all of them with helper functions
that use the irq_remap_ops to hook into an implementation specific
implementation.

I have done basic testing on this patch-set on a VT-d machine with
interrupt remapping and found no regression so far. But as usual this
doesn't mean that there is none ;-)

Anyway, since I am on vacation soon I sent out these patches to receive
all kinds of comments so that I can start over to add the AMD part when
I am back.

Thanks,

Joerg
