From c610ec60ed6354157ea7b0c9c9a7236126ef416b Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 26 Jul 2016 21:29:30 +1000 Subject: [PATCH] powerpc/mm: Move disable_radix handling into mmu_early_init_devtree() Move the handling of the disable_radix command line argument into the newly created mmu_early_init_devtree(). It's an MMU option so it's preferable to have it in an mm related file, and it also means platforms that don't support radix don't have to carry the code.
