From f573bbc7a7773b8fc0d62be6b79345f5a971d97d Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Fri, 14 Oct 2016 14:26:24 -0400 Subject: [PATCH] pkeys: Remove easily triggered WARN This easy-to-trigger warning shows up instantly when running Trinity on a kernel with CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS disabled. At most this should have been a printk, but the -EINVAL alone should be more than adequate indicator that something isn't available.
