From 855f9a8e87fe3912a1c00eb63f36880d1ad32e40 Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Tue, 4 May 2021 18:38:13 -0700 Subject: mm: generalize SYS_SUPPORTS_HUGETLBFS (rename as ARCH_SUPPORTS_HUGETLBFS) SYS_SUPPORTS_HUGETLBFS config has duplicate definitions on platforms that subscribe it. Instead, just make it a generic option which can be selected on applicable platforms. Also rename it as ARCH_SUPPORTS_HUGETLBFS instead. This reduces code duplication and makes it cleaner.
