Considering <> is
slated for 5.19, that seems fine, as this will remove what is hopefully
the last hardirq FPU user.

The bigger motivation, though, for removing the hardirq FPU code would
be for just simplifying the FPU handling. The VirtualBox people are
going to have to fix this bug anyway, since it also affects old kernels
they support.
