[patch 15/24] Add text_poke and sync_core to powerpc
- Needed on architectures where we must surround live instruction modification with "WP flag disable". - Turns into a memcpy on powerpc since there is no WP flag activated for instruction pages (yet..). - Add empty sync_core to powerpc so it can be used in architecture independent code.
