__free_page() and free_pages() - Differences?

[Chirayu Patel <chirayu@wipro.tcpn.com>]

Hi ,

I am having trouble understanding the difference between 
the __free_page function and free_pages function in page_alloc.c

The only difference which I can see is that free_pages decrement map->count
while __free_page decrements the page->count. Both of them eventually make
a call to free_pages_ok with identical parametrs. 

Can anyone shed some light on this?
