Remove managed_page_count_lock spinlock and instead use atomic

Hello Joe,
Perhaps better to define and use macros for the accesses
instead of specific uses of atomic_long_<inc/dec/read>

Something like:

#define totalram_pages() (unsigned long)atomic_long_read(&_totalram_pages) #define totalram_pages_inc() (unsigned long)atomic_long_inc(&_totalram_pages) #define totalram_pages_dec() (unsigned long)atomic_long_dec(&_totalram_pages)

That sounds like a nice idea.

Regards,
Arun
