Which SUSY models are affected by the recent LHCb result?

The LHCb has recently published the observation of $B_s \rightarrow \mu^+ \mu^-$ with a branching ratio that agrees with the Standard Model (SM). There are many blog posts about it (See: Of Particular Significance). The result initiated a debate over its implication on Supersymmetry in general, which I don't want to discuss here. But it certainly affects some Supersymmetric models that may have a different prediction than that of the SM.

My questions are,

1. Which models in particular are affected (or variants of models)? What is the MSSM status? The NMSSM?
2. Does the result affect some of the parameter space of a particular model, or does it rule out an entire model/or variant of a model?

 Related to, but perhaps more sophisticated than physics.stackexchange.com/questions/44052/… – dmckee♦ Nov 15 '12 at 19:49 Thanks indeed for this. Dr. Motl's answer helps a lot. Especially the comment that models requiring large $\tan \beta$ and squarks below 1 TeV. But I hope to get a more elaborative answer here. – stupidity Nov 15 '12 at 20:11
