[Xen-devel] [PATCH 0/2] Implement VFP context switch for arm32

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hello,

This small patch series implement the VFP context for arm32.

I didn't implement the arm64 support, and just add dummy function to avoid
compilation breakage on this platform.

The second patch remove VFP support on XEN because we can let the guest
to enable when it's required by a process.

Cheers,

  xen/arm: don't enable VFP on XEN during the boot
