--- Comment #9 from Linus Torvalds <torvalds@linux-foundation.org> ---
Looks like STV is "scalar to vector" and it should have been disabled
automatically by the -mno-avx flag anyway.

And the excessive stack usage was perhaps due to GCC preparing all those stack
slots for integer -> vector movement that then never happens exactly because
the kernel uses -mno-avx?

So if I understand this right, the kernel can indeed just add -mno-stv to work
around this.

?
