From d386825c959efeaae3315c25dd2d2874c68829c7 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Wed, 30 Mar 2016 16:45:57 +0200 Subject: [PATCH] arm64: mm: free __init memory via the linear mapping The implementation of free_initmem_default() expects __init_begin and __init_end to be covered by the linear mapping, which is no longer the case. So open code it instead, using addresses that are explicitly translated from kernel virtual to linear virtual.
