reduce large do_mount stack usage with noinlines
do_mount() uses a whopping 616 bytes of stack on x86_64 in 2.6.24-mm1, largely thanks to gcc inlining the various helper functions. noinlining these can slim it down a lot; on my box this patch gets it down to 168, which is mostly the struct nameidata nd; left on the stack. These functions are called only as do_mount() helpers; none of them should be in any path that would see a performance benefit from inlining...
