On May 9, 64 bit PMON on Loongson is solved. Former PMON is 32bit despite a 64bit CPU. The developers said that the advantages to use a 64bit PMON :
1. We can get access to anywhere in the 64bit space by C pointers in PMON
2. DDR can be locate to any place in PMON. (???I don't know such technical stuffs so it might be a translation mistake）
3. Tool chain is gcc 3.4.6, which is consistent to 2.6 kernel tool chain.
