The amount committed in this crisis by the US alone is close to $ 8 trillion. The breakdown by Bloomberg is here and a recent update is here. The amount actually spent so far is closer to $ 3.5 trillion, but that’s still a big number. 
OMG! It’s astonishing to see a graph like the one above, showing the incredible scale of money the US government is putting into this financial crisis. I vote this the understatement of the year:
“No question there is some credit risk there.” – William Poole, former president of the Federal Reserve Bank of St. Louis, commenting on Citigroup receiving “$306 billion of government guarantees for troubled mortgages and toxic assets. The Treasury Department also will inject $20 billion into the bank after its stock fell 60 percent last week.” (from the Bloomberg link you provided in your blog).
