[SPARC]: Fix exec failures on sun4c.
This deals with a sun4c issue caused by commit b6a2fea39318e43fee84fa7b0b90d68bed92d2ba: mm: variable length argument support. The new way the code works means that sun4c_update_mmu_cache gets called before a context has been selected, which results in invalid operation of the underling mm code. Simply ignoring update requests when there is no valid context solves the problem. Signed-off-by Mark Fortescue <mark@mtfhpc.demon.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
