I would recommend to just avoid linux headers which get not _installed_ by:
make headers_install

You can easily identify such headers by looking into the Kbuild of the same
directory as the header file is located.

Example:
dgollub@marvin:~/projects/linux-2.6/include/linux> grep connector.h Kbuild 
unifdef-y += connector.h
# GOOD for inclusion
dgollub@marvin:~/projects/linux-2.6/include/linux> grep compiler.h Kbuild 
dgollub@marvin:~/projects/linux-2.6/include/linux> 
# BAD for inclusion

Note: this also requires checking if the header file is available also in older
kernel releases - or got removed in more recent releases (e.g. asm/page.h, ...)

Btw. is there any "kernel-release-range" LTP should build/support?
Like 2.6.0 to latest? Or 2.6.14 to latest? Or something like that?

Hope that helps.

best regards,
Daniel
