Hi Paul,
After merging the rcu tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
net/core/dev.c: In function 'netdev_run_todo':
net/core/dev.c:5294: error: dereferencing pointer to incomplete type
net/core/dev.c:5294: warning: type defaults to 'int' in declaration of '_________p1'
net/core/dev.c:5294: error: dereferencing pointer to incomplete type
net/core/dev.c:5294: warning: type defaults to 'int' in declaration of 'type name'

net/core/dev.c:5294: error: dereferencing pointer to incomplete type
net/core/dev.c:5294: warning: type defaults to 'int' in declaration of 'type name'
Caused by commit ca5ecddfa8fcbd948c95530e7e817cee9fb43a3d ("rcu: define
__rcu address space modifier for sparse") interacting with commit
95ae6b228f814fc0528d0506ee9f18ac333d6851 ("ipv4: ip_ptr cleanups") from
the net tree.
rcu_dereference_raw() now needs to know the type of the object its
argument points to. I added the following merge fix (which could be
applied to the net tree anyway).

Subject: [PATCH] net: include inetdevice.h for rcu_dereference_raw api change
rcu_dereference_raw() now needs to know the type of its argument.
