Bug#940820: UML not loading on Debian buster with a 5.2 kernel from testing

[Anton Ivanov]

This is a regression in the randomization of the va setting.
UML will boot on debian 4.19 kernel host  with kernel.randomize_va_space = 2

UML will not boot debian 5.2 kernel host with kernel.randomize_va_space = 2

UML will boot on 5.2 once kernel.randomize_va_space is set to 0 on the host.

So something has changed in how randomize is implemented between 4.19 
and 5.2.
