btrfs: fix empty_zero_page misusage Heiko Carstens noticed that btrfs was using empty_zero_page incorrectly. He explained: The definition of empty_zero_page is architecture specific. It is (currently) either a character array, an unsigned long containing the address of the empty_zero_page, or even worse only the address of the struct page belonging to the empty_zero_page. This commit changes btrfs to use a for-loop instead. On x86 the resulting .ko is smaller, and we're no longer worrying about how each arch builds its zeros.
