[SPARC64]: Bulletproof hypervisor TLB flushing.
Check TLB flush hypervisor calls for errors and report them. Pass HV_MMU_ALL always for now, we can add back the optimization to avoid the I-TLB flush later. Always explicitly page align the virtual address arguments. Signed-off-by: David S. Miller <davem@davemloft.net>
