From 3f584e7ec1931dad298df512ec6a61a948d2a5e9 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 10 Feb 2014 14:09:48 -0300 Subject: [PATCH] perf trace: Fix ioctl 'request' beautifier build problems on !(i386 || x86_64) arches commit 844ae5b46c08dbc7ba695b543c023f9cf3bbf9ff upstream. Supporting decoding the ioctl 'request' parameter needs more work to properly support more architectures, the current approach doesn't work on at least powerpc and sparc, as reported by Ben Hutchings in http://lkml.kernel.org/r/1391593985.3003.48.camel@deadeye.wl.decadent.org.uk . Work around that by making it to be ifdefed for the architectures known to work with the current, limited approach, i386 and x86_64 till better code is written.
