Subject: linux-next: build failure after merge of the final tree
 (net-current tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

net/l2tp/l2tp_core.c:1228: error: __ksymtab_l2tp_tunnel_closeall causes a section type conflict
net/l2tp/l2tp_core.c:1228: error: __ksymtab_l2tp_tunnel_closeall causes a section type conflict

net/l2tp/l2tp_core.c:847: error: __ksymtab_l2tp_udp_recv_core causes a section type conflict

Caused by commit fc130840d75d42c5a360fd1d8b72489eec09cad3 ("l2tp: make
local function static") since these functions are now static (and should
not be exported).  I wish doing that caused a build failure on other
architectures ...

I applied the following patch:
