This changed a lot since v1, basically what remains is the idea that
we want to have some sort of array of interrupts and some sort of
separation between processors.
At the end of this series we'll have:
- One file with all interrupt implementations (interrupts.c);
- Separate files for each major group of CPUs (book3s, booke,
32bits). Only interrupt code for now, but we could bring pieces of
cpu_init into them;
- Four separate interrupt arrays, one for each of the above groups
plus KVM.
- powerpc_excp calls into the individual files and from there we
dispatch according to what is available in the interrupts array.
Please comment,
Thanks.
