Create a guard area between VMAs to detect memory corruption.
This is a pretty major change that has a bunch of end-user implications.
It's not dependent on any debugging options and can't be turned on/off
by individual apps, at runtime, or even at boot.
Its connection to this series is also tenuous and not spelled out in the
exceptionally terse changelog.
I agree. We did have application failures due to the introduction of
the stack gap, so this change is likely to cause failures when applied
to existing mappings as well.
