From 6cb4814c87cb1282b4a1d35e73743e8dd1b12ec5 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 17 Apr 2016 23:31:34 +0200 Subject: [PATCH] arch/x86: remove support for i386 The Linux kernel doesn't even support i386 anymore, there is no NPTL support for i386 and uClibc-ng only supports NPTL on x86, so there is essentially no usable thread implementation. Most likely glibc and musl also don't support i386 either. So it's time to remove the support for this architecture variant.
