[PATCH] fixes for oprofile on ppc64

[Anton Blanchard]

Hi,

Here are a few fixes I needed when porting oprofile to ppc64:

- __PAGE_OFFSET isnt defined for all architectures, use PAGE_OFFSET
  instead
- include linux/cache.h everywhere we use ____cacheline_aligned etc. 
  Otherwise we end up with a structure called ____cacheline_aligned
  and no alignment :(
