This enables sparse for ia64 and adds a basic set of __user
annotations.  Apart for sys_execve() and the uaccess.h changes, the
patch is trivially safe.  Also note that in gcc_intrin.h, I
changed "asm __volatile" to "asm volatile" since sparse didn't
like the old version (and it's a "strane" version anyhow).
Patch has been (boot) tested.
