I just pushed the fixed patch to the end of zedd/kernel:

     linux-yocto/kernel-meta: ktype refactoring: move DEBUG_KERNEL, 
EXPERT and EMBEDDED

     Integrating the folliwing patch series from Cal:

       This patch series refactors the ktypes so that base and standard 
ktypes
       do not enable EMBEDDED, EXPERT, or DEBUG_KERNEL. The reason this
       decision was made is because production platforms likely do not want
       DEBUG_KERNEL enabled, and EMBEDDED selects EXPERT which selects
       DEBUG_KERNEL.

       A new ktype called "developer" was also created. This ktype
       enables the options now missing from standard and base, making it 
easy
       to maintain the functionality of a BSP through simply swapping 
the ktype
       from standard to developer. The preempt-rt ktype is now based off of
       developer in order to maintain its functionality.

       The new standard ktype does not include EMBEDDED, EXPERT, or
       DEBUG_KERNEL. Without DEBUG_KERNEL it loses a number of debug 
features
       that are selected by default. Without EXPERT it gains 
RFKILL_INPUT and
       DEBUG_MEMORY_INIT, while losing VMSPLIT_3G. These are only 
available to
       configure with CONFIG_EXPERT=y and default to EXPERT or !EXPERT. Not
       selecting EMBEDDED has no apparent impacts.

       Some coordination is required for this change, as existing BSPs 
WILL be
       affected, and will either need to accept the changes in the standard
       ktype or move to the developer ktype.

       California Sullivan (12):
         features/debug: add debug-kernel feature
         ktypes: add developer ktype
         ktypes/base: Disable EMBEDDED and DEBUG_KERNEL
         CONFIG_PROCESSOR_SELECT: do not enable
         intel-common-drivers.scc: move profiling and latencytop to a 
new file
         romley.scc remove profiling and latencytop features
         bsp/intel-common: add intel-core* developer BSPs
         preempt-rt.scc: include developer ktype instead of standard
         intel-common: add intel-developer-drivers.scc to preempt-rt BSPs
         CONFIG_I2C_I801: set option to yes in intel-core* BSPs
         bsp: add developer common-pc BSPs
         bsp: remove profiling and latencytop from non-developer 
common-pc BSPs
