* Note that CONFIG_MODVERSIONS=n since v4.9-rc4. It was causing i386
modprobe issues because the CRC for some assembler variables were not
being correctly computed. Linus disabled it altogether for 2 rc's,
then restored it at the end in combination with some patches that
set CRC to 0 for assembler variables. I chose to leave it disabled
in light of the Ubuntu policy to revise the package ABI on every upload.

Title:
Ubuntu 16.10 KVM: Running out of memory if trying to bringup guest
with more than 64VFs.

== Comment: #0 - Carol L. Soto - 2017-01-04 12:03:57 ==
---Problem Description---
If user try to create a guest with more than 64 VFs then the guest will have
issues to come up but if user keeps trying to bringup this guest over and over
the system will eventually start seeing out of memory messages.
Like this:
Jan 3 14:33:13 ltc-fire1 kernel: [ 1053.950753] systemd invoked oom-killer:
gfp_mask=0x26000d0(GFP_TEMPORARY|__GFP_NOTRACK), order=0, oom_score_adj=0
Jan 3 14:33:16 ltc-fire1 kernel: [ 1053.950757] systemd cpuset=/
mems_allowed=0
Jan 3 14:33:16 ltc-fire1 kernel: [ 1053.950761] CPU: 104 PID: 1 Comm:
systemd Tainted: G OE 4.8.0-34-generic #36-Ubuntu
Jan 3 14:33:16 ltc-fire1 kernel: [ 1053.950763] Call Trace:
---uname output---
Linux ltc-fire1 4.8.0-34-generic #36 SMP Tue Jan 3 15:27:22 CST 2017 ppc64le
ppc64le ppc64le GNU/Linux
---Additional Hardware Info---
we are using Mellanox CX4 card with SRIOV enabled to be able to create a
guest with more than 64 VFs.
Machine Type = P8
---Steps to Reproduce---
create a guest with more than 64 VFs and then just try to bring up the guest
by
virsh start --console ltc-fire1-vm3-ubuntu-16.10-69VFs.
Will attach example guest xml.

If I build a kernel with these upstream patches, then I do not see the memory
leaks messages in dmesg:
