Hi,

Patch 1 and 2 mainly fix bug about balloon not working correctly when we do
hotplug memory. It takes 'ram_size' as VM's real RAM size which is wrong
after we hotplug memory.

This bug exists since we begin to support hotplug memory, and it is better
to fix it.

Patch 3 add some trace events, it helps debugging balloon. If it is unnecessary, 
pls feel free to remove it.

Thanks,
zhanghailiang

v2:
- fix compiling break for other targets that don't support pc-dimm
