This is on a Thinkpad 760EL. 
 
so I really need tpctlir. 
 
without USE="tpctlir" it compiles fine.

Reproducible: Always

This looks you are compiling an SMP module for a non-SMP kernel. In
asm.system.h: 

#ifdef CONFIG_SMP 

extern void __global_cli(void); 
extern void __global_sti(void); 
extern unsigned long __global_save_flags(void); 
extern void __global_restore_flags(unsigned long); 
#define cli() __global_cli() 
#define sti() __global_sti() 
#define save_flags(x) ((x)=__global_save_flags()) 
#define restore_flags(x) __global_restore_flags(x) 

Added a patch that makes it compile regardless of CONFIG_SMP setting, but
I'm not certain it works perfectly anymore. (According to the Linux IO Programming
Mini-HOWTO, my new approach is how to do it, but it's probably outdated....)

fix works fine.
emerged and works fine.
thanks a lot!
