I recently had to install kernel 4.6 in my Ubuntu 16.04 to stop the random "suspend" crashes.

After install I ran:

sudo vmware-modconfig --console --install-all

and got the error:

VMs wouldn't run with an error regarding been unable to load vmmon

It appears get_user_pages was replaced with get_user_pages_remote

With this patch: https://lkml.org/lkml/2016/2/10/555

To resolve:

(From Arch linux wiki:)

https://wiki.archlinux.org/index.php/VMware#Kernel_modules_fail_to_build_after_Linux_4.6

cd /usr/lib/vmware/modules/source
tar xf vmmon.tar
mv vmmon.tar vmmon.old.tar
sed -i -e 's/get_user_pages/get_user_pages_remote/g' vmmon-only/linux/hostif.c
tar cf vmmon.tar vmmon-only
rm -r vmmon-only
tar xf vmnet.tar
mv vmnet.tar vmnet.old.tar
sed -i -e 's/get_user_pages/get_user_pages_remote/g' vmnet-only/userif.c
tar cf vmnet.tar vmnet-only
rm -r vmnet-only

To me it seems like this is a linux patch breaking userspace, am I wrong?
