I am unable to find the implementation for rdmsr_safe_regs(). lxr <http://lxr.free-electrons.com/ident?i=rdmsr_safe_regs> only mentions references and a prototype definition.

I've also manually grepped through the entire kernel source tree and have not been able to find where rdmsr_safe_regs is defined.

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.
