> * Add a variable called KERNEL_LOCALVERSION which when set will
>   place a version string in the .scmversion file of the kernel
>   sources.  This string will be picked up by the kernel Makefile
>   and will be appended to the kernel version.  This is done to
>   make it easier to identify what revision of the kernel sources
>   are being run.  For example you can use a setting like the
>   following to add the short commit id to the kernel version
>   string:
> 
> KERNEL_LOCALVERSION = "-g${@d.getVar('SRCPV',
> True).partition('+')[2][0:7]}"
