From c2f29ea111e3344ed48257c2a142c3db514e1529 Mon Sep 17 00:00:00 2001 From: Benjamin LaHaise Date: Tue, 21 Jun 2005 17:14:55 -0700 Subject: [PATCH] __read_page_state(): pass unsigned long instead of unsigned By making the offset argument of __read_page_state an unsigned long instead of unsigned, we can avoid forcing the compiler to sign extend a usually constant argument. This saves 1 instruction on x86-64.
