From 41401db698cbb5d1869776bf336881db267e7d19 Mon Sep 17 00:00:00 2001 From: Jaswinder Singh Rajput Date: Thu, 8 Jan 2009 15:42:46 +0530 Subject: x86: rename intel_mp_floating to mpf_intel Impact: cleanup, solve 80 columns wrap problems intel_mp_floating should be renamed to mpf_intel. The reason: the 'f' in MPF already means 'floating' which means MP Floating pointer structure - no need to repeat that in the type name.
