Subject[PATCH 01/14] kbuild: search arch/$ARCH/include before include/
Date
The namespace used in arch/$ARCH/include is different from
what is used in include/ except for the include/asm directory.

This patch gives the arch/$ARCH/include/asm directory priority
over include/asm.

When we add asm-offsets.h to arch/$ARCH/include/asm/ this
patch makes sure we pick up the arch specific version
and not the one we have in include/asm.

The situation with an asm-offsets.h file located in
both include/asm _and_ arch/$ARCH/include/asm will happen
when we move more files over to include/generated.

This happens because in some cases it is not practical
to rename all users so we simply add a file
in arch/$ARCH/include/asm that includes the generated version.

This is the solution we use for asm-offsets.h as an example.
