From c1137c37a9370f510dc022e6e95fff036ccb90be Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 24 Jun 2008 11:32:48 +1000 Subject: [PATCH] powerpc: Consolidate feature fixup macros for 64/32 bit Currently we have three versions of MAKE_FTR_SECTION_ENTRY(), the macro that generates a feature section entry. There is 64bit version, a 32bit version and version for 32bit code built with a 64bit kernel. Rather than triplicating (?) the MAKE_FTR_SECTION_ENTRY() logic, we can move the 64bit/32bit differences into separate macros, and then only have one version of MAKE_FTR_SECTION_ENTRY().
