hi list,
since i am trying to compile 2.6.24/25 kernel with the rt-patches, no 
one version will compile here and i always get the same output.
this is how it looks like while trying to compile 2.6.21.4-rt13, but it 
looks the same for 2.6.21.5-rt14 :

 LD      .tmp_vmlinux1
kernel/built-in.o:(.data+0x5d8): undefined reference to 
`preempt_mark_thresh'
make: *** [.tmp_vmlinux1] Fehler 1

does the patch below fix this?
