[PATCH v2 02/37] KVM: PPC: Book3S HV: Fix CONFIG_SPAPR_TCE_IOMMU=n default hcalls

From: Nicholas Piggin <npiggin@gmail.com>
Date: 2021-02-25 13:48:21
Subsystem: kernel virtual machine for powerpc (kvm/powerpc), linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

This config option causes the warning in init_default_hcalls to fire
because the TCE handlers are in the default hcall list but not
implemented.
