Changes

The Armv9 '''Scalable Vector Extensions verision 2''' (SVE2) provide a variable-witdh SIMD capability for [[AArch64]] systems. Note that SVE2 is a minor refinement and standardization of the original Scalable Vector Extensions (used on the [https://www.r-ccs.riken.jp/en/fugaku/ Fugaku] supercomputer), so most materials discussing SVE are also applicable to SVE2 (which will be used on systems ranging from smartphones to servers to supercomputers).
