The memory part MAP_FIXED is to avoid (desired !=3D region) (do not know ho= w that relates to aslr but with this it runs with aslr), the jit code has to do so= me cache sync in order to execute the wirte+exec pages, it was guarded out, and the problem was masked under w^x because mprotect also does some cache syncing.. ,thanks Kyle Evans. Hopefully someone will pick this up for a test. Do not forget bug #275247 O= nly tested on aarch64 rpi4 and rk3399.
