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?

hi ingo, very much thanks for the patch, it is fixing the issue here.
i applied it to the 2.6.21.5-rt14 with '- p1' and the kernel just
compiled successfully!
i am hurrying to do a reboot and check the performance now -thanks again!
cheers,
doc
