From 5cd272085bbc905532869f3e1fd18a7100496b56 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Mon, 27 Mar 2006 23:43:27 -0600 Subject: powerpc: move math-emu over to arch/powerpc Towards the goal of having arch/powerpc not build anything over in arch/ppc move math-emu over. Also, killed some references to arch/ppc/ in the arch/powerpc Makefile which should belong in drivers/ when the particular sub-arch's move over to arch/powerpc.
