For 1.1 we can just use USE_STATIC_CODE_GEN_BUFFER. It should not have major problems on Linux, since it is already tested for linux-user. That leaves out Windows of course.
This raises the question of why we don't use the static buffer everywhere. Presumably there was a disadvantage that caused us to move to the dynamic mmap for system mode...
(I don't actually think it should be very hard to make the ARM code cope with the idea that jumps into host code might be long range.)
