Subject: [PATCH] powerpc/64s/exception: move head-64.h exception code to
 exception-64s.S

References: jsc#PM-1334 jsc#SLE-9246 jsc#SLE-9251
Patch-mainline: v5.4-rc1
Git-commit: a243281195c338489ec5088380821f64340cb82f

The head-64.h code should deal only with the head code sections
and offset calculations.

No generated code change except BUG line number constants.
