From 1e8fed873e7499bab8da05b2006f6a3960796c68 Mon Sep 17 00:00:00 2001 From: "Mike Rapoport (IBM)" <rppt@kernel.org> Date: Fri, 24 Mar 2023 08:22:29 +0300 Subject: [PATCH] powerpc: drop ranges for definition of ARCH_FORCE_MAX_ORDER PowerPC defines ranges for ARCH_FORCE_MAX_ORDER some of which are insanely allowing MAX_ORDER up to 63, which implies maximal contiguous allocation size of 2^63 pages. Drop bogus definitions of ranges for ARCH_FORCE_MAX_ORDER and leave it a simple integer with sensible defaults. Users that *really* need to change the value of ARCH_FORCE_MAX_ORDER will be able to do so but they won't be mislead by the bogus ranges.
