Error building after merging upstream 3.7.7

Error building after merging upstream 3.7.7

[Aaron W. Hsu]

I have managed to use bcache rather successfully for a while now, and I 
wanted to try getting the latest changes to the bcache branch into my 
kernel. At the same time, I wanted to merge in the latest linux stable 
changes.

I did a merge of linux-stable/linux-3.7.y into the HEAD of the bcache 
branch, which seems to have worked without issue, however, after I 
configured the kernel, attempting to build the kernel errors out with the 
following message:

  LD      init/built-in.o
kernel/built-in.o:(.data+0x8bc8): undefined reference to `bcache_subsys'

Is there something I have totally missed here?

I would *really* love to see a single .patch that can be applied to 
3.7.x kernels. This would allow me to start producing some kernel RPMs 
for using bcache on EL6 systems.

I've tried producing something that works, but haven't had much success 
in patching bcache into the vanilla kernel. Having a single patch that 
can be easily refactored as newer 3.7.x releases are done would be heaven.

I'm using bcache on the 3.7.9 kernel. I documented how I made the patch on the
Arch Wiki:
