Commit 549d62d889b4 ("KVM: PPC: use definitions in epapr header
for hcalls") from the kvm-ppc tree added an include of asm/epapr_hcall.h
to the user visible part of asm/kvm_para.h so asm/epapr_hcall.h became a
user visible header file.

The UAPI changes are moving the user visible parts of export header files
into a separate include directory called uapi.
