Thanks for removing the somewhat misleading references to AVX, SVE and RVV.
But please do include the references to the earlier reverted attempt at
reenabling this - that is key to why this may work better now than it did
last time.
And to make it clear: The commit message itself really should contain this
information, it's not enough to reference information elsewhere on
patchwork/ML archives for such essential parts of the change.
