    Subject[PATCH 5.11 390/775] powerpc/kvm: Force selection of CONFIG_PPC_FPU
    Date
    From: Christophe Leroy <christophe.leroy@csgroup.eu>

    [ Upstream commit 27f699579b64dbf27caf31e5c0eac567ec0aa8b8 ]

    book3s/32 kvm is designed with the assumption that
    an FPU is always present.

    Force selection of FPU support in the kernel when
    build KVM.

    Fixes: 7d68c8916950 ("powerpc/32s: Allow deselecting CONFIG_PPC_FPU on mpc832x")
