Description of problem:
Unable to compile VirtualBox kernel module after upgdating from kernel 4.2.8-200.fc22.x86_64 to 4.3.6-201.fc22.x86_64

Version-Release number of selected component (if applicable):


How reproducible:

/etc/init.d/vboxdrv setup


Steps to Reproduce:
1.su root
/etc/init.d/vboxdrv setup
2.
3.

Actual results:
