From 96177299416dbccb73b54e6b344260154a445375 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Sat, 10 Feb 2007 01:43:03 -0800 Subject: [PATCH] Drop free_pages() nr_free_pages is now a simple access to a global variable. Make it a macro instead of a function. The nr_free_pages now requires vmstat.h to be included. There is one occurrence in power management where we need to add the include. Directly refrer to global_page_state() there to clarify why the #include was added.
