Before implementing KASLR for arm64 by building a self-relocating PIE executable, we have to ensure that values we use before the relocation routine is executed are not subject to dynamic relocation themselves. This applies not only to virtual addresses, but also to values that are supplied by the linker at build time and relocated using R_AARCH64_ABS64 relocations. So instead, use assemble time constants, or force the use of static relocations by folding the constants into the instructions.
