[PATCH 1/3] mm: Silence vmap() allocation failures based on caller gfp_flags

[Florian Fainelli]

If the caller has set __GFP_NOWARN don't print the following message:
vmap allocation for size 15736832 failed: use vmalloc=<size> to increase
size.

This can happen with the ARM/Linux module loader built with
CONFIG_ARM_MODULE_PLTS=y which does a first attempt at loading a large
module from module space, then falls back to vmalloc space.
