Subject: PAGE_SIZE on 64bit and 32bit machines

According to my knowledge the PAGE_SIZE on 32bit architectures in 4KB. 
Logically, the PAGE_SIZE on 64bit architectures should be 8KB. That's at 
least the way I understand it. However, looking at the kernel code of 
x86_64, I see the PAGE_SIZE is 4KB.

Can anyone explain to me what am I missing here?

Thanks
