On todays linus tree the following compile error happened to me:

This patch fixes this issue by adding "linux/cache.h" as an include to
"include/net/dst_ops.h".

Strange. Compiling b43legacy from the linux-2.6.git tree (git describe is
v2.6.36-4464-g229aebb) works fine on x86_64. I wonder what is different.

Exactly the same git describe here.
Maybe your arch includes cache.h already, in my case its a compile for ARM (shmobile).

That probably makes the difference. Using Eric's fix that removes the #include
<linux/dst.h> should be better. Does it work for you?

There are probably a lot more of the system includes that may not be needed. If
I send you a patch removing them, could you test?
