title: Compile Kernel module on Chromebook
body: <p>I am running an ARMv7 Chromebook with crouton. I would like to get CIFS shares mounted, but it appears that CIFS is not in the kernel. So I downloaded the same kernel version source as I am on, compiled the cifs.ko module, and attempted to load it. But I received this error:</p>
  
  <pre><code># insmod cifs.ko
  insmod: ERROR: could not insert module cifs.ko: Operation not permitted
  </code></pre>
  
  <p>The module is compiled as an ARM module, I checked with file:</p>
  
  <pre><code># file cifs.kocifs.ko: ELF 32-bit LSB relocatable, ARM, version 1, BuildID[sha1]=e14d1772583fae478e2b113b57ce81c214e511af, not stripped
  </code></pre>
  
  <p>What gives?</p>
