Sorry for sending this to the wrong list.  

This is a valid question, the difference will be faster integration and
better testing /validation of upstream (or possibly pending upstream )
patches for Intel Hardware.

Since the kernel will be coming from an Intel Source, it will be fully
tested on more hardware that the current linux-yocto kernel gets tested
against.

The update rate maybe about the same, with security updates as needed
for more severe issues

As other vendors maintain kernels for their meta-vendor specific layer,
Intel has chosen to maintain an Intel kernel based on the current LTS
version (4.9) plus upstreamed patches. All content will be backports
from internally maintained tracking trees being regularly updated.

meta-intel will likely continue to contain the linux-yocto-<latest> for
a non-LTS kernel.

Hope that clarifies this.

Sau!
