The attached test patch fixes a potential race in the kernel which might result in missing TLB flushes.
In addition it adds a "notlblc" kernel parameter which allows to disable the local TLB clearing optimization.

Note: this is just a test patch to verify if it solves the seen problem. This patch should currently not go into an official kernel release.

@Canonical can you please build a test kernel which includes this patch?

The patch is against kernel version 4.4.0-89.112.

Thank you!
