[PATCH v4 12/12] exec: Fix overlap of PAGE_ANON and PAGE_TARGET_1


From: Richard Henderson
Subject: [PATCH v4 12/12] exec: Fix overlap of PAGE_ANON and PAGE_TARGET_1
Date: Tue, 6 Apr 2021 10:40:31 -0700

Unfortuately, the elements of PAGE_* were not in numerical
order and so PAGE_ANON was added to an "unused" bit.
As an arbitrary choice, move PAGE_TARGET_{1,2} together.
