Zachary Leaf	2ecbbcc7ca	arm64: extend ESR/SPSR registers to 64b ... For the Exception Syndrome Register, ESR_ELx, the upper 32b were previously unused, but now may contain additional exception info as of Armv8.7 (FEAT_LS64). Extend ESR from u32->u64 in exception handling code to support this. In addition, also extend Saved Program Status Register SPSR_ELx in the same way to allow for future extensions.
