[POWERPC] Export empty_zero_page
Once again, this time with feeling.... - Ted >From c91cfaabc17f8a53807a2f31f067a732e34a1550 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o <tytso@mit.edu> Date: Wed, 12 Mar 2008 11:50:39 -0400 Subject: Export empty_zero_page The empty_zero_page symbol is exported by most other architectures (s390, ia64, x86, um), and an upcoming ext4 patch needs it because ZERO_PAGE() references empty_zero_page, and we need it to zero out an unitialized extents in ext4 files.
