From 34affcd7577a232803f729d1870ba475f294e4ea Mon Sep 17 00:00:00 2001 From: "Mike Rapoport (IBM)" Date: Fri, 24 Mar 2023 08:22:21 +0300 Subject: arm64: drop ranges in definition of ARCH_FORCE_MAX_ORDER It is not a good idea to change fundamental parameters of core memory management. Having predefined ranges suggests that the values within those ranges are sensible, but one has to *really* understand implications of changing MAX_ORDER before actually amending it and ranges don't help here. Drop ranges in definition of ARCH_FORCE_MAX_ORDER and make its prompt visible only if EXPERT=y Link: https://lkml.kernel.org/r/20230324052233.2654090-3-rppt@kernel.org Signed-off-by: Mike Rapoport (IBM) Reviewed-by: Zi Yan Reviewed-by: Kefeng Wang Cc: Arnd Bergmann Cc: Catalin Marinas Cc: Christophe Leroy Cc: David Miller Cc: Dinh Nguyen Cc: Geert Uytterhoeven Cc: Guo Ren Cc: John Paul Adrian Glaubitz Cc: Kirill A.
