Problem Buildingwith Yocto due to wrong symlink

[MarkusEich]

Dear all,

I am working to build the kernel using the yocto embedded toolchain https://www.yoctoproject.org. It does not work out of the box because the build process in Kernel 3.4 creates a recursive symbolic link while building /drivers/gpu/arm/mali400/ump

The reason for this behaviour in the 3.4.y kernel is the commit 73341c8 where arch-release is added. It was removed in commit 9a3fbdc.

The following path fixes this issue.

Link arch to the selected arch-config directory

$(shell [ -L $(src)/arch ] && rm $(src)/arch)
-$(shell ln -sf arch-$(CONFIG) $(src)/arch)
+$(shell ln -sf $(src)/arch-$(CONFIG) $(src)/arch)
$(shell touch $(src)/arch/config.h)
endif

Maybe add this fix to the master branch?

We can safely ignore MP400 drivers on XU kernel...
