Hi Thomas,

Considering <https://git.zx2c4.com/linux-rng/commit/?id=e3e33fc2e> 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.
