Re: (subset) [PATCH v3 0/3] arm64/sve: Document our actual SVE syscall ABI

Currently our SVE syscall ABI documentation does not reflect the actual implemented ABI, it says that register state not shared with FPSIMD becomes undefined on syscall when in reality we always clear it. Since changing this would cause a change in the observed kernel behaviour there is a substantial desire to avoid taking advantage of the documented ABI so instead let's document what we actually do so it's clear that it is in reality an ABI.

Applied to arm64 (for-next/doc), thanks!
