#     powerpc/64s/radix: Fix radix segment exception handling
#     
#     Commit 48e7b76957 ("powerpc/64s/hash: Convert SLB miss handlers to C")
#     broke the radix-mode segment exception handler. In radix mode, this is
#     exception is not an SLB miss, rather it signals that the EA is outside
#     the range translated by any page table.
#     
#     The commit lost the radix feature alternate code patch, which can
#     cause faults to some EAs to kernel BUG at arch/powerpc/mm/slb.c:639!
#     
#     The original radix code would send faults to slb_miss_large_addr,
#     which would end up faulting due to slb_addr_limit being 0. This patch
#     sends radix directly to do_bad_slb_fault, which is a bit clearer.
#
