On ppc, sparc, and other non-x86 platforms, when you perform load/store instructions within the port I/O space window, the PCI controller emits the IN/OUT transactions exactly as if an x86 processor had executed an in{bwl}/out{bwl} instruction. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
