On x86, it looks like a 3k increase in text size. I know Matt Tolentino has been testing it on x86_64, he might have a comparison there for you. $ size i386-T41-laptop*/vmlinux text data bss dec hex filename 2897131 580592 204252 3681975 382eb7 i386-T41-laptop.sparse/vmlinux 2894166 581832 203228 3679226 3823fa i386-T41-laptop/vmlinux BTW, this PAE is on and uses 36-bits of physaddr space. -- Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
