[PATCH 0/5] context_tracking: Flatter archs not using exception_enter/exit() v3

From: Frederic Weisbecker
Date: Tue Nov 17 2020 - 10:16:49 EST


In this new version, I fixed the changelogs according to peterz's review.
Especially on the 2nd patch where I added lots of details to better
understand what exception_enter/exit() do and what is required to get
rid of it.

Also rebased against -rc4.

Thanks,
