It was April 29th 2008 when commit
093a088b76352e0a6fdca84eb78b3aa65fbe6dd1 where the ext4_ext_zeroout()
routine was introduced (it is this routine that makes use of the
ZERO_PAGE macro expanding to an expression that contains a reference
to the empty_zero_page global symbol). After this commit, the patches
similar to the one found in this thread were made for several
architectures. Apparently, MIPS has been overlooked.
