[linux-yocto] KERNEL_FEATURES variable, Kernel Configuration Fragments and Kernels other than linux-yocto

[Poole, Donald R.]

Hello All,

I'm currently working on building a custom image for the Raspberry Pi with SELinux enabled through the meta-selinux layer, but the layer doesn't seem to be able to modify the linux-raspberrypi kernel with the SELinux kernel configuration fragment as required.  So after doing some research on the topic and coming across this thread discussion, http://patches.openembedded.org/patch/36315/, it seems that the linux-yocto kernel is the only kernel that supports the kernel configuration fragment management system and the KERNEL_FEATURES variable (Richard Purdie and Saul Wold discuss and mention this toward the bottom of the discussion).  So, my question is: Is there a timeline for opening up the kernel configuration fragment management system to work with kernels other than the linux-yocto* kernels? If this capability is already available, how would I go about incorporating the kernel configuration fragment management system into a kernel other than the linux-yocto kernel?  I haven't quite figured it out yet, so any assistance would be greatly appreciated.  Thanks in advanced!
