Much better, but I think you want to make use of these in non-kvm code to=
o,
no? At least the LE one is definitely already implemented as call :)
Sure but that's a different patch.... below.

powerpc/pseries: Use new defines when calling h_set_mode

Now that we define these in the KVM code, use these defines when we call
h_set_mode.  No functional change.

This depends on the KVM h_set_mode patches.
