You can use plain old 'wc' to count lines. Most of the Linux kernel codebase is drivers. 2nd most is architecture specific code.

I don't know what's the actual count of lines of code that I actually have on the kernel compiled on my specific x64 machine, but I think considering how many significant changes were made to the Linux kernel over the years, I don't think it's a victim of unnecessary bloat. The various virtualization features alone were industry changing features.
