A minor build fix for 64-bit FLATMEM configs. A fix for a boot failure on 32-bit powermacs. My commit to fix CLOCK_MONOTONIC across Y2038 broke the 32-bit VDSO on 64-bit kernels, ie. compat mode, which is only used on big endian. The rewrite of the SLB code we merged in 4.20 missed the fact that the 0x380 exception is also used with the Radix MMU to report out of range accesses. This could lead to an oops if userspace tried to read from addresses outside the user or kernel range.
