The patch titled
m68k: clean up uaccess.h
has been added to the -mm tree. Its filename is
m68k-clean-up-uaccessh.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: m68k: clean up uaccess.h
From: Roman Zippel <zippel@xxxxxxxxxxxxxx>
This uninlines a few large functions in uaccess.h and cleans up the rest.
It includes a (hopefully temporary) workaround for the broken typeof of
gcc-4.1.
