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.
