Subject: module: allow ndiswrapper to use GPL-only symbols
X-Git-Tag: v2.6.25-rc4~1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b37ccfc637be27d9a652fcedc35e6e782c3aa78;p=linux-2.6

module: allow ndiswrapper to use GPL-only symbols

A change after 2.6.24 broke ndiswrapper by accidentally removing its
access to GPL-only symbols.  Revert that change and add comments about
the reasons why ndiswrapper and driverloader are treated in a special
way.
