powerpc: Remove unreachable relocation on exception handlers
We have relocation on exception handlers defined for h_data_storage and h_instr_storage. However we will never take relocation on exceptions for these because they can only come from a guest, and we never take relocation on exceptions when we transition from guest to host. We also have a handler for hmi_exception (Hypervisor Maintenance) which is defined in the architecture to never be delivered with relocation on, see see v2.07 Book III-S section 6.5. So remove the handlers, leaving a branch to self just to be double extra paranoid. Signed-off-by:Michael Ellerman <michael@ellerman.id.au> CC: <stable@vger.kernel.org> [v3.9+] Signed-off-by:
