Subject: m68k: Export empty_zero_page for ZERO_PAGE usage in modules.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5fcf4303037a648f7b3e40c9a73361879852efe7;p=deliverable%2Flinux.git

m68k: Export empty_zero_page for ZERO_PAGE usage in modules.

ext4 uses ZERO_PAGE(0) to zero out blocks.  We need to export
different symbols in different arches for the usage of ZERO_PAGE
in modules.
