From c53e0baa6f34b7051790e0fba9d782ec4efe58bd Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Tue, 28 Jul 2015 10:31:06 +0100 Subject: [PATCH] arm64: mm: mark create_mapping as __init Currently create_mapping is marked with __ref, apparently because it refers to early_alloc. However, create_mapping has no logic to prevent erroneous use of early_alloc after it has been freed, and is only ever called by __init functions anyway. Thus the __ref marker is misleading and unnecessary. Instead, this patch marks create_mapping as __init, resulting in warnings if it is used from a a non __init functions, and allowing its memory to be reclaimed.
