Public bug reported:

This is essentially the same issue as 1818049 but I am bringing it to
the kernel team's attention as it breaks more than just virtualbox: The
signature for get_user_pages was changed from -142 to -143, which breaks
some out-of-tree or DKMS module builds.

In particular, it breaks even the latest version of parallels tools,
which forced me to downgrade to -138 after staying in the office late to
try and figure out why the heck it suddenly didn't work. This is a
showstopper for anyone using parallels as the behavior they'll see off
the bat is that they can no longer log in to a graphical session.

I think it's likely that other out-of-tree modules will be broken as
well. It seems like it might be easier to work around this in the kernel
itself rather than patch every single other package that tickles it.
