Subject: KVM: PPC: Book3S HV: Fix invalid use of register expression
Patch-mainline: v4.14-rc1
Git-commit: 0bfa33c7f71e7e9de289582d9652110daa1ec8a1
References: bsc#1077761

binutils >= 2.26 now warns about misuse of register expressions in
assembler operands that are actually literals. In this instance r0 is
being used where a literal 0 should be used.
