Regarding the DDB ifndef, probably there must be
a bit in ARM64 saying "disable page protection", so it could be set when
we enter DDB, and we could remove the ifndef.

It only matters when setting / removing breakpoints, so it seems like you want to defer changing page protection right until then.

Even if there's not a single bit that will do it (I honestly don't know), why not just fiddle with the L2 descriptor directly?
