powerpc/mm: Fix reporting of kernel execute faults on the 8xx
[ Upstream commit ffca395b11c4a5a6df6d6345f794b0e3d578e2d0 ]
On the 8xx, no-execute is set via PPP bits in the PTE. Therefore
a no-exec fault generates DSISR_PROTFAULT error bits,
not DSISR_NOEXEC_OR_G.
This patch adds DSISR_PROTFAULT in the test mask.
