I assume it affects Jessie as well since it is a fundamental issue
JavaScript on arm64. The JS engine provides 47 bits of JSValue for
the virtual address space while arm64 requires 48 bits.
Looking at the patch upstream [1], you can see that the issue with
address bits being used by the JS engine affects many architectures.
It's definitely a good idea to backport this.
