Nicholas Piggin	540d4d34be	powerpc/64: context tracking move to interrupt wrappers ... This moves exception_enter/exit calls to wrapper functions for synchronous interrupts. More interrupt handlers are covered by this than previously.

Nicholas Piggin	8d41fc618a	powerpc: interrupt handler wrapper functions ... Add wrapper functions (derived from x86 macros) for interrupt handler functions. This allows interrupt entry code to be written in C.
