Hi all,
After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:
net/netlink/af_netlink.c: In function 'netlink_frame_flush_dcache':
net/netlink/af_netlink.c:384:40: error: 'NL_MMAP_MSG_HDRLEN' undeclared (first use in this function)
Caused by commit 9652e931e73b ("netlink: add mmap'ed netlink helper
functions"). This needed to be build tested on an architecture that has
ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE set to 1 (like Sparc :-)).
I added the following patch for today:
