From 729f10014af6598855f00cf0fa45df78640c269d Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Wed, 28 Nov 2018 15:51:20 +0100 Subject: [PATCH] x86: fix paging_max_paddr_bits() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit paging_max_paddr_bits() has an invalid use of IS_ENABLED(): instead of IS_ENABLED(CONFIG_BIGMEM) it is using IS_ENABLED(BIGMEM). Fix that.
