+Subject: [PATCH] arm64: mm: place __cpu_setup in .text
+
+We drop __cpu_setup in .text.init, which ends up being part of .text.
+The .text.init section was a legacy section name which has been unused
+elsewhere for a long time.
+
+The ".text.init" name is misleading if read as a synonym for
+".init.text". Any CPU may execute __cpu_setup before turning the MMU on,
+so it should simply live in .text.
+
+Remove the pointless section assignment. This will leave __cpu_setup in
+the .text section.
