The problem is that we do not enable CONFIG_CC_STACKPROTECTOR in our
x86_84 build test and that we got caught. Could you try the following patch?
diff --git a/include/asm-x86/wrappers_64.h b/include/asm-x86/wrappers_64.h
index a61f6ba..0d04b9c 100644
--- a/include/asm-x86/wrappers_64.h
+++ b/include/asm-x86/wrappers_64.h
@@ -78,4 +78,8 @@ typedef union thread_xstate x86_fpustate;
#define x86_fpustate_ptr(t) ((t)->fpu.state)
#endif
+#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,34)
+#define per_cpu_var(var) (var)
+#endif /* Linux >= 2.6.34 */
+
#endif /* _XENO_ASM_X86_WRAPPERS_64_H */
Also note that the configuration you posted is not suitable for running
Linux with Xenomai, please have a look at this page:

Hi all,
I'm trying to compile linux 2.6.35.7 on an x86 non 64 with Xenomai, and it
return the advice to disable CONFIG_CC_STACKPROTECTOR (with an error). I'm
now compiling with CONFIG_CC_STACKPROTECTOR disable.
Is it the same "problem" (apparently not)?
Regards,
Cyril

Different issue. Xenomai does not support stack protection on x86_32.
