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

gcc -Wall -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -ffreestanding -O2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -g -D__arch_um__ -DSUBARCH=\"i386\" -Iarch/um/include -I/usr/src/linux-2.6.13/arch/um/kernel/tt/include -I/usr/src/linux-2.6.13/arch/um/kernel/skas/include -Dvmap=kernel_vmap -Derrno=kernel_errno -Dsigprocmask=kernel_sigprocmask -fno-unit-at-a-time -U__i386__ -Ui386 -D_LARGEFILE64_SOURCE -Wdeclaration-after-statement -Wno-pointer-sign -nostdinc -isystem /usr/lib/gcc/i386-redhat-linux/4.0.0/include -D__KERNEL__ -Iinclude -S -o arch/um/kernel-offsets.s arch/um/sys-i386/kernel-offsets.c
In file included from arch/um/sys-i386/kernel-offsets.c:3:

include/linux/sched.h:1465: error: ‘TIF_NEED_RESCHED_DELAYED’ undeclared (first use in this function)

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

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.
