Hey Ben,

Sparse is giving a warning about vcpu_sbi_ext_pmu not being
defined, so add a definition to the relevant header to fix
the following:
arch/riscv/kvm/vcpu_sbi_pmu.c:81:37: warning: symbol 'vcpu_sbi_ext_pmu' was not declared. Should it be static?
Fixes: 3e5e56c60a1477 ("riscv: kvm: move extern sbi_ext declarations to a header")
You sure this is the right fixes tag? This code didn't exist when I
wrote that commit, should the fixes tag not be
Fixes: cbddc4c4cb9e ("RISC-V: KVM: Add SBI PMU extension support")
instead?
I think you're right there.
Cheers,
Conor.
