From fd4fd5aac1282825195c6816ed40a2a6d42db5bf Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Sat, 3 Sep 2005 15:54:30 -0700 Subject: [PATCH] mm: consolidate get_order Someone mentioned that almost all the architectures used basically the same implementation of get_order. This patch consolidates them into asm-generic/page.h and includes that in the appropriate places. The exceptions are ia64 and ppc which have their own (presumably optimised) versions.
