This patch does simple things:
- intruduces an bc_magic field on beancunter to make sure
union on struct page is correctly used in next patches
- adds nr_beancounters
- adds unused_privvmpages variable (counter of privvm pages
which are not mapped into VM address space and thus potentially
can be allocated later)
+static inline void privvm_uncharge(struct beancounter *bc, unsigned long sz)

I hit this path, when I do not enable CONFIG_BEANCOUNTERS_RSS. I suspect it has
something to do with the code in mod_rss_pages(). I suspect the that
CONFIG_BEANCOUNTERS_RSS needs to be enabled to get the accounting right.
In addition, Could you please make this a warning with KERN_WARNING.

+ bc_update_privvmpages(bc);
