The series enables Multi-Threaded TCG on PPC64
Patch 01: Use atomic_cmpxchg in store conditional
02: Handle first write to page during atomic operation

conditional
Patches are based on ppc-for-2.10
Tested using following:
./ppc64-softmmu/qemu-system-ppc64 -cpu POWER8 -vga none -nographic
-machine pseries,usb=off -m 2G -smp 8,cores=8,threads=1 -accel
tcg,thread=multi f23.img
I tried it with a Ubuntu 16.04.2 guest using stress --cpu 8. It looked
good : the CPU usage of QEMU reached 760% on the host.
What was your guest operating system?
