In keeping with other important requirements in architecture code, this fact is undocumented. Additionally, as the function consists of three instructions totalling 12 bytes with no literal pool data, a smaller alignment of 16 bytes would be sufficient. This patch reduces the alignment to 16 bytes and documents the underlying reason for the alignment. This reduces the required alignment of the entire .head.text section from 64 bytes to 16 bytes, though it may still be aligned to a larger value depending on TEXT_OFFSET.
