target-ppc: Introduce tm_enabled Bit to CPU State
Add a bit (tm_enabled) to CPU state that mirrors the MSR[TM] bit. This is analogous to the other "available" bits in the MSR (FP, VSX, etc.). NOTE: Since MSR[TM] occupies big-endian bit 31, the code is wrapped with a PPC64 bit check. Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
