    KVM: Add compat ioctl for KVM_SET_SIGNAL_MASK · 1dda606c
    Alexander Graf authored
    KVM has an ioctl to define which signal mask should be used while running
    inside VCPU_RUN. At least for big endian systems, this mask is different
    on 32-bit and 64-bit systems (though the size is identical).
    
    Add a compat wrapper that converts the mask to whatever the kernel accepts,
    allowing 32-bit kvm user space to set signal masks.
    
    This patch fixes qemu with --enable-io-thread on ppc64 hosts when running
    32-bit user land.
