Building with a custom git kernel the kernel headers that end up in the staging directory to compile packages against are not from the kernel that I have selected to build for the system. 

I am building with an older 2.6.35 kernel from our own git repo but the kernel headers that packages are compiled against are from a newer version. The problem showed up when tslib wouldn't load because the ev version differed and when I check the staging directory sure enough the include/linux/input.h has a different EV_VERSION than my 2.6 kernel.

I'm not sure where its pulling the headers from? I did a little digging but couldn't figure out where it attempts to find them.

This is from the 2012.11.1 release, I downloaded the git version as well and the same problem exists. I am cross compiling for armv5te on i.mx28 evk with codesourcery toolchain downloaded by buildroot. I'd be happy to implement a patch if someone could point in the right direction for where to look in the build system to find where it pulls in the kernel headers.
