Frederic Weisbecker 56dd9470d7 context_tracking: Move exception handling to generic code
Exceptions handling on context tracking should share common
treatment: on entry we exit user mode if the exception triggered
in that context. Then on exception exit we return to that previous
context.

Generalize this to avoid duplication across archs.
