Commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the
wrapper to fit the kernel") adjusts the wrapper address unnecessarily
for platforms that use arch/powerpc/boot/of.c, since the code there
allocates space for the kernel wherever it can find it and doesn't
necessarily load the kerne

Sorry again for the lateness. I tried to get this done before the
conferences last week, but it just didn't happen.
Highlights include corenet board file consolidation, the ability to run
userspaces with lwsync on e500v1/v2, some cleanup patches that other KVM
patches will build on, support for s

Move the few declarations from arch/powerpc/kernel/setup.h
into arch/powerpc/include/asm/setup.h. This resolves a

in the prior path.
