From e4e961e36f063484c48bed919013c106d178995d Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" <kirill.shutemov@linux.intel.com> Date: Fri, 18 May 2018 13:35:28 +0300 Subject: [PATCH] x86/mm: Mark __pgtable_l5_enabled __initdata __pgtable_l5_enabled shouldn't be needed after system has booted. All preparation is done. We can now mark it as __initdata. Signed-off-by: Kirill A.
