The purpose is probably to work around 32bit DMA limited devices on the broken iAMD64 systems.
But I think it's a bad idea, x86_64 doesn't use CONFIG_HIGHMEM at all currenly, and it could easily use it for that purpose like in the patch in older RH kernels for ia64. - 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/
