The patch moves the struct IO_APIC_route_entry to a common place. This allows us to share the struct with iosapic. Thanks, -- Dexuan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The patch makes some pci access functions architecture independent. It only moves the 2 functions from xen/arch/x86/pci.c to xen/drivers/pci/pci.c.

asm-generic/barrier.h defines a nop() macro. To be able to use this header on ia64, we shouldn't call local functions/variables nop(). There's one instance where this breaks on ia64: rename the function to iosapic_nop to avoid the conflict. Signed-off-by: Michael S.
