Add a trace point for tlbie(l) (Translation Lookaside Buffer Invalidate Entry (Local)) instructions. The tlbie instruction has changed over the years, so not all versions accept the same operands. Use the ISA v3 field operands because they are the most verbose, we may change them in future. Example output: qemu-system-ppc-5371 [016] 1412.369519: tlbie: tlbie with lpid 0, local 1, rb=67bd8900174c11c1, rs=0, ric=0 prs=0 r=0 Signed-off-by: Balbir Singh <bsingharora@gmail.com> [mpe: Add some missing trace_tlbie()s, reword change log] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
