[PATCH] Fix usage of setup_arg_pages() in IA64, MIPS, S390 and Sparc64

[David Howells <dhowells@redhat.com>]

The attached patch fixes the usage of setup_arg_pages() in the IA64, MIPS,
S390 and Sparc64 arches. This function now takes an extra parameter: the
initial top of stack. This is useful in uClinux when there's no fixed location
to which the stack pointer can be initialised.
