That does not work for a new architecture. There is nothing to bisect.

Crap. a single patch is a major PITA for review. It's even worse than
211 per file patches.

It's ok to have several patches ordered by topics

- generic header stuff
- processor and system headers
- low level entry and setup code
- process/thread related code
- mm related code
- timers
- interrupts
- ptrace
- signals
- fault handling
- misc
- build system, main makefile, Kconfig

That makes it actually feasible to review.

Thanks,
