title: Where do I find the version of a Linux kernel source tree?
body: <p>I have downloaded from a hardware vendor just a tarball of their Linux source tree (no Git repository metadata), is there a way to find out the version number of the kernel?</p>
  
  <p>Is the version number usually stored in a file somewhere in the source tree?</p>
  
  <p>I'd like to be able to do this without compiling and running the kernel.</p>
