btrfs: allow extent buffer helpers to skip cross-page handling
Currently btrfs extent buffer helpers are doing all the cross-page
handling, as there is no guarantee that all those eb pages are
contiguous.
However on systems with enough memory, there is a very high chance the
page cache for btree_inode are allocated with physically contiguous
pages.
In that case, we can skip all the complex cross-page handling, thus
speeding up the code.
This patch adds a new member, extent_buffer::addr, which is only set to
non-NULL if all the extent buffer pages are physically contiguous.
