fix building against 4.12

[karolherbst]

it still works for 4.11, didn't test older kernels

[Lekensteyn]

Should work with older kernels too, it was first introduced with torvalds/linux@c22ce14 which includes asm/uaccess.h

Thanks!

[Lekensteyn]

Oops, accidentally merged to master. Now force-pushed (sorry!) the previous master and fast-forwarded the change to develop branch

[karolherbst]

@Lekensteyn ohh right, I should have made the request against develop. Maybe it makes sense to move the default branch to develop as well, as this affects the default branches for cloning/PRs as well?

[Lekensteyn]

Normally the master branch is the stable version that should be used, but as there is not that much development now it might indeed make sense to mark the develop branch as default. I'll think about it.

[metabubble]

When will that change reflect in the bumblebee gentoo overlay?

[karolherbst]

@metabubble you can change the branch of the live ebuild, you could add this to your portage settings: "bbswitch_LIVE_BRANCH=develop"
