    [PATCH] ppc64 POWER3 segment table fix · c5e296f5
    Anton Blanchard authored
    The ppc64 fix last week (enforcing permissions on the kernel when
    accessing userspace pages) uncovered a bug on POWER3/RS64. We werent
    zeroing the segment table entry before overwriting it and it was possible
    for the ks bit to be set on a kernel segment.
    
    The VSID mask was also changed to match reality (we only use 13 bits).
