Hi Bjorn,
In this v2, I made the following changes according to your suggestion:
1) The iohook driver is now built-in so we have alot fewer exported
symbols. But we still need to export two functions because the
loadable modules need to call into the I/O Hook.
2) Non-PCI part moved from drivers/pci into drivers/misc/iohook
3) It's now platform neutral. The PCI part should now work on all
platforms. The memory mapped I/O part can be easily extened later
to non-x86 platforms by modifying their part under arch/
I tested this new version on Westmere-EX. It worked as expected.
