You might try something with clang-format.  It doesn't have a built-in 
style option for the kernel (probably because the kernel can't currently 
be compiled with Clang/LLVM, but Linux does qualify for the first two 
criteria for having a new style default added, so if someone wants to 
actually work on it, they could probably get it included), but something 
like this for the config should get you pretty close:

BasedOnStyle: LLVM
IndentWidth: 8
UseTab: Always
BreakBeforeBraces: Linux
AllowShortIfStatementOnASingleLine: false
IndentCaseLabels: false

I'm pretty certain that this doesn't cover everything from CodingStyle, 
but it should cover most things, and most of the other stuff should be 
relatively easily scriptable using regex based replacements.
