Just confirmed: Required when building against home-brewed kernels with
split source/binaries. Avi, please merge.

This removes -Iarch/${ARCH_DIR}/include when KERNELSOURCEDIR is not
defined. What is the reason for this change?

As far as I can see (I do wear my glasses today...),
-Iarch/${ARCH_DIR}/include is present in the else part of $(if).
The reason for this change is the missing arch include from the source
directory in case it's separate from the build dir (yeah, the changelog
has room for improvements).
I ran into the same issue after building and installing a recent kernel
tree with O=. The split trees SUSE leaves behind do not suffer from
this, but they also still work after the change. Same for classic
unified trees.

Yeah, I missed the comma. Maybe I need to visit your optometrist.

Okay, will apply the patch.

No you've interpreted the change wrong. The "else" part of the if clause
ensures this is not removed.
Here is how the make if call works:
$(if <string>,<string for true clase>,<string for else clause>)
What my patch does do is *add* this define in for the case when
KERNELSOURCEDIR is defined, but at the correct source location.
I'd like to ask again if anybody is testing this builds properly against
an out of place kernel build, as I've needed these patches across
several different machines running different distributions at work, so
I'm very sceptical that it can work for many people, doesn't mean I'm
right though..
Thanks, James
