From b171e4093017d4d6e411f5e97823e5e4a21266a2 Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Thu, 5 Nov 2015 18:47:06 -0800 Subject: mm/page_alloc: remove unused parameter in init_currently_empty_zone() Commit a2f3aa025766 ("[PATCH] Fix sparsemem on Cell") fixed an oops experienced on the Cell architecture when init-time functions, early_*(), are called at runtime by introducing an 'enum memmap_context' parameter to memmap_init_zone() and init_currently_empty_zone(). This parameter is intended to be used to tell whether the call of these two functions is being made on behalf of a hotplug event, or happening at boot-time. However, init_currently_empty_zone() does not use this parameter at all, so remove it.
