[PATCH] mm/page_poison: Make early_page_poison_param __init

From: Dou Liyang
Date: Tue Jan 16 2018 - 22:48:20 EST


The early_param() is only called during kernel initialization, So Linux
marks the function of it with __init macro to save memory.

But it forgot to mark the early_page_poison_param(). So, Make it __init
as well.
