From 6cb3a59fd5e754c3627b79db21c5bcc284bfd721 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Mon, 13 Jul 2015 09:39:15 +0200 Subject: x86: flatten hierarchy It never made sense to have bootblock_* in init, but pirq_routing.c in boot, and some ld scripts on the main level while others live in subdirectories. This patch flattens the directory hierarchy and makes x86 more similar to the other architectures.
