Hi David,
Today's linux-next merge of the msm tree got a conflict in
arch/arm/Kconfig.debug between several commits from the arm tree and
commit 7bd51cd4526d ("ARM: msm: Move debug-macro.S to include/debug")
from the msm tree.
I fixed it up (I think - see below) and can carry the fix as necessary

There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic

Although the bulk of the code is architecture agnostic, the code needs to
run a precisely sized loop which is implemented in assembler.

The overall count of objects on a node might be accurate, but the
moment it is returned to the caller it is no longer perfectly
accurate. Hence we don't really need to hold the node lock to
protect the read of the object. The count is a long, so can be read
atomically on all pl

There's a small consistency problem between the inode and writeback
naming. Writeback calls the "for IO" inode queues b_io and
b_more_io, but the inode calls these the "writeback list" or
i_wb_list. This makes it hard to an new "under writeback" list to
the inode, or call it an

Need append "_D__linux__" to KBUILD_CFLAGS, just like some of another
architectures have done, or 'allmodconfig' can not pass compiling.

Hoho, Tomi has applied the patch from Lius to fix this warning.
And this is the sixth patch to fix the same issue since last week.

As a part of pseries_idle backend driver cleanup to make
the code common to both pseries and powernv archs, it
is necessary to move the backend-driver code to powerpc/sysdev.
As a pre-requisite to that, it is essential to move plpar_wrapper.h
to include/asm.

Move pseries_idle backend driver code to arch/powerpc/sysdev
so that the code can be used for a common driver for powernv
