I truly believe it should be cpu_to_le32(). No. Both are slightly wrong semantically but le32_to_cpu() is less wrong :-) iowrite32 supposedly takes a "cpu" value as argument and writes an "le" value. So if anything, you need something that converts to a "cpu" value before you call iowrite32. Now it's still slightly wrong because the "input" to le32_to_cpu() is supposed to be an "LE" value but of course here it's not, it's a "cpu" value too :-) But yes, I agree with aw here, either do nothing or stick a set of iowriteXX_native or something equivalent in the generic iomap header, define them in term of iowrite32be/iowrite32 based on the compile time endian of the arch. Hitting asm-generic/iomap.h I think will cover all archs except ARM. For ARM, just hack arch/arm/asm/io.h Cheers, Ben. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
