The real reason is that the rdtsc{,_ordered}() methods use the 
EAX_EDX_*() macros to optimize their EDX/EAX assembly accessors, which 
is why these methods were in <asm/msr.h>.

Your followup patch tacitly acknowledges this by silently creating 
duplicate copies of these facilities in both headers ...

I've cleaned it all up in tip:x86/msr via these preparatory patches:

  x86/msr: Improve the comments of the DECLARE_ARGS()/EAX_EDX_VAL()/EAX_EDX_RET() facility
  x86/msr: Rename DECLARE_ARGS() to EAX_EDX_DECLARE_ARGS
  x86/msr: Move the EAX_EDX_*() methods from <asm/msr.h> to <asm/asm.h>

Thanks,
