[Qemu-devel] [PATCH 02/13] arm: Add support for M profile CPUs having different MMU index semantics

2017-04-25 Thread Peter Maydell
The M profile CPU's MPU has an awkward corner case which we would like to implement with a different MMU index. We can avoid having to bump the number of MMU modes ARM uses, because some of our existing MMU indexes are only used by non-M-profile CPUs, so we can borrow one. To avoid that getting to
