Much better, but I think you want to make use of these in non-kvm code too,
no? At least the LE one is definitely already implemented as call :)
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.

Which header are these coming from, and why aren't we including it? And is it
going to still build with CONFIG_KVM=n?
From include/asm/hvcall.h in the h_set_mode patch set I sent before.
And yes it compiles with CONFIG_KVM=n fine.
Please split that patch into one that adds the definitions and one that
changes the KVM code to use those definitions. Both Ben and me can then
apply the definition patch and our respective tree patch.
