Hi all,
I am trying to debug the RT patched kernel with UML. But it is showing
these errors
My kernel version is 2.6.13 and applied patch-2.6.13-rt14 to this kernel

That's odd. Did the patch apply cleanly?
TIF_NEED_RESCHED_DELAYED should be defined in
include/asm-i386/thread_info.h for an i386
target.

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.
