The existing patching alias page setup and teardown sections can be
simplified to make use of the new open_patch_window() abstraction.

This eliminates the _mm variants of the helpers, consumers no longer
need to check mm_patch_enabled(), and consumers no longer need to worry
about synchronization and flushing beyond the changes they make in the
patching window.

With this patch, the time needed to activate or de-activate function 
tracer is approx 10% longer on powerpc 8xx.
