    Patch was applied properly, for an i386 target it was compiled with out
    any errors, and it is working properly.
     When i try to complile the rt patch applied kernel
    i didnot found TIF_NEED_RESCHED_DELAYED in include/asm-um/thread_info.h
    Is there any separate patch required for debugging rtpatched kernel with
    UML.
