Since RFC: - Rebased on Christophe's v3 ppc32 conversion - Fixed up small details, adds some powerpc-wide cleanups at the end.
Since v1: - Christophe's review comments accounted for: - Split common code interrupt changes for 64e from 64e conversion. - Removed unnecessary ifdef additions from common interrupt code. - Keep interrupt return context tracking debug check for 64e when it switches to new context tracing. - __bad_page_fault is made static in page fault cleanup. - CPU time accounting asm and asm offsets can be removed with 64e conversion. Tested on qemu only (QEMU e500), which is not ideal for interrupt handling particularly the critical interrupts which I don't know whether it can generate.
