Modified Files:
        src/sys/arch/powerpc/include/oea: pmap.h

Log Message:
Clamp PMAP_DIRECT_MAPPED_LEN below USER_SR/KERNEL_SR

Derive it from MIN(USER_SR, KERNEL_SR) so the direct-mapped region never
overlaps the kernel HTAB window on ports where KERNEL_SR < USER_SR,
like ofppc. This made pmap_pvo_find_va() panic on legit lookup misses.
