(In reply to Jesper Schmitz Mouridsen from comment #25)
Ok the difference in my understanding between arm64 and arm64/aarch64 on AMD64
the address pointer is always a valid firefoz jit region i.e 47th bit and above
are never set. This is not true for arm64 so MapAlignedPagesRandom returns null
when the last attempts are not in a validRange. Furthermore I cannot confirm
that linuxes randomizes mmap'ed virtual addresses, so TryToAlignChunk works
better there.
