+Subject: Revert "ACPICA: AML interpreter: add region addresses in global list during initialization"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 22083c028d0b3ee419232d25ce90367e5b25df8f which is
+commit 4abb951b73ff0a8a979113ef185651aa3c8da19b upstream.

+
+       making it sound like it was fixing an actual bug. This is not the case.
+       The commit fixes a side issue discovered while investigating bug
+       #200011. It does NOT fix bug #200011 itself (as explicitly reported by
+       Jean-Marc at https://bugzilla.kernel.org/show_bug.cgi?id=200011#c65 ).
+
+       It does however cause regressions, despite what the commit message says. See:
+
+       https://bugzilla.kernel.org/show_bug.cgi?id=201721
+
+       and I expect more similar regressions, as ACPI resource conflicts are
+       very frequent.
+
+       This commit was not stable material to start with. It is intrusive,
+       presents a risk of side effects, and does not solve an actual bug that
+       is bothering users.
