Subject: Balloon down memory failed in x86 PAE mode when memory size>4G

Hi

I implemented balloon in windows pv driver, it works normally on x86 and 
x64 OS.
However, i hit problem to balloon down memory on x86 PAE mode VM when 
it's memory
size is larger than 4G.

Furthermore, i tested linux PVHVM too. Balloon driver also failed to 
take effect
at the same situation.

So, is there anything missed in windows or linux PV driver when 
ballooning down
memory on x86 PAE VM(memory>4G)? or is there a limitation in Xen for PAE 
mode?

Thanks
Annie.
