[OE-core] Cannot apply patches out of meta bsp after applied a kern-tool patch

[LIYONG]

Hi all,

After applied the below patch, bitbake cannot apply these patches in my app layer. For example, there is a kernel patch in meta-app/recipes-kernel/linux-yocto/linux-yocto, I add the file in linux-yocto_%.bbappend file. bitbake yocto-linux will fail with "do patch error". If I revert the patch, the build is okay. 

Any suggestions/comments?

    patching: only validate user supplied patches by default
 
    Previously the patching tools would consider both system and user
    supplied patches in the same manner .. they are simply a series of
    patches to be applied to a branch, and that the scripts should determine
    where in the series to start (based on what is already on the branch).
 
    This detection was causing a few problems:
 
      - time consuming
      - starting in the middle of a series when intermediate patches were
        merged to a branch.
 
    To solve both the performance and start detection, we instead simply
    note the transition from system (i.e. already defined features and
    series) and user/recipe supplied patches. When the transition is noted,
    the system will start pushing ALL patches without doing autoresume
    detection.
 
    Control in keeping the series up to date is passed to the user, and
consistent behaviour/performance is achieved.
