And? What is the high level effect to the user?

'setup_data for kaslr from boot stage becomes all 0's' is not a high
level effect. It's a detail of the mechanism of the bug, not a high
level effect.

Think of a regular Linux user reading your changelogs. The first
paragraph of bug fixes should be readable to them!

_That_ is what 'high level' means.

Thanks,
