From af27d9403f5b80685b79c88425086edccecaf711 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 16 Feb 2018 16:25:53 +0100 Subject: mm: hide a #warning for COMPILE_TEST We get a warning about some slow configurations in randconfig kernels: mm/memory.c:83:2: error: #warning Unfortunate NUMA and NUMA Balancing config, growing page-frame for last_cpupid. [-Werror=cpp] The warning is reasonable by itself, but gets in the way of randconfig build testing, so I'm hiding it whenever CONFIG_COMPILE_TEST is set. The warning was added in 2013 in commit 75980e97dacc ("mm: fold page->_last_nid into page->flags where possible").
