powerpc: Fix string instr. emulation for 32-bit processes on ppc64 String instruction emulation would erroneously result in a segfault if the upper bits of the EA are set and is so high that it fails access check. Truncate the EA to 32 bits if the process is 32-bit. Signed-off-by: James Yang <James.Yang@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
