Is there some trick to building allyesconfig on PowerPC?  When I do try that, I
get all sorts of weird build errors, and it dies long before it gets to my
driver.  I get stuff like:

  LD      arch/powerpc/sysdev/xics/built-in.o
WARNING: arch/powerpc/sysdev/xics/built-in.o(.text+0x1310): Section mismatch in
reference from the function .icp_native_init() to the function
.init.text:.icp_native_init_one_node()
The function .icp_native_init() references
the function __init .icp_native_init_one_node().
This is often because .icp_native_init lacks a __init
annotation or the annotation of .icp_native_init_one_node is wrong.

and

  AS      arch/powerpc/kernel/head_64.o
arch/powerpc/kernel/exceptions-64s.S: Assembler messages:
arch/powerpc/kernel/exceptions-64s.S:1151: Error: attempt to move .org backwards
arch/powerpc/kernel/exceptions-64s.S:1160: Error: attempt to move .org backwards
make[1]: *** [arch/powerpc/kernel/head_64.o] Error 1

I guess I don't have the right compiler.

Anyway, I think I know how to fix the break that Stephen is seeing.  I will post
a v4 patch in a few minutes.
