Try http://lxr.free-electrons.com/source/arch/x86/lib/msr-reg.S

If I can not grep out the definition of a function by its name, I will
try to grep with part of its name again, because most likely it is
created by a macro. In your case, I tried "grep safe_regs" under
arch/x86/ and got what you need.
