#     powerpc/64s: Fix scv implicit soft-mask table for relocated kernels
#     
#     The implict soft-mask table addresses get relocated if they use a
#     relative symbol like a label. This is right for code that runs relocated
#     but not for unrelocated. The scv interrupt vectors run unrelocated, so
#     absolute addresses are required for their soft-mask table entry.
#     
#     This fixes crashing with relocated kernels, usually an asynchronous
#     interrupt hitting in the scv handler, then hitting the trap that checks
#     whether r1 is in userspace.
#
