Subject: x86: move __addr_ok to uaccess.h.
X-Git-Tag: v2.6.27-rc1~1106^2~46^2~12
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=002ca1690c3d0a495e6aedd608281aeb01ce6385;p=linux-2.6

x86: move __addr_ok to uaccess.h.

Take it out of uaccess_32.h. Since it seems that no users
of the x86_64 exists, we simply pick the i386 version.
