Hmm, it sounds asm/msi.h shouldn't be included from common headers. :<
I think the attached patch might be better. How about this?

Default msi_arch_init() looks sufficient for most ia64 platforms
except for SGI SN2, which seems to need its special version.
gregkh-pci-msi-vector-targeting-abstractions.patch used machvec
to switch the functions between platforms.
For that, it included asm/msi.h from asm/machvec.h and
caused the warnings flood.
The attached patch separates machvec function and the original
inline function. So that we don't need to include asm/msi.h from
common headers.


There is another problem that CONFIG_IA64_GENERIC still doesn't
build due to error in SGI SN specific code.
It needs additional fix.
