From 03497d761c55438144fd63534d4223418fdfd345 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 27 Apr 2017 11:19:00 -0700 Subject: [PATCH] mm: Silence vmap() allocation failures based on caller gfp_flags If the caller has set __GFP_NOWARN don't print the following message: vmap allocation for size 15736832 failed: use vmalloc= to increase size. This can happen with the ARM/Linux or ARM64/Linux module loader built with CONFIG_ARM{,64}_MODULE_PLTS=y which does a first attempt at loading a large module from module space, then falls back to vmalloc space.
