Subject: [PATCH] target/arm: Check for dp support for dp VFM, not sp
In commit 1120827fa182f0e7622 we accidentally put the
"UNDEF unless FPU has double-precision support" check in
the single-precision VFM function. Put it in the dp
function where it belongs.
Backports commit 34bea4edb9bbe8edf4b8606276482acdff5ca58b from qemu
