Hi!
The configuration option SCHED_OMIT_FRAME_POINTER seems to have gained a
most unusual description in 2.6.34.
490 config SCHED_OMIT_FRAME_POINTER
491 def_bool y
492 prompt "Single-depth WCHAN output"
493 depends on X86
494 ---help---
495 Calculate simpler /proc/<PID>/wchan values. If this option
496 is disabled then wchan values will recurse back to the
497 caller function. This provides more accurate wchan values,
498 at the expense of slightly more scheduling overhead.
499
500 If in doubt, say "Y".

This looks like a git merge error/bug.
