From 5c97cac63ac24c78c8126958a453774e49e706dd Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 16 Jun 2017 11:39:15 -0300 Subject: [PATCH] tools: Adopt __aligned from kernel sources To have a more compact way to ask the compiler to use a specific alignment, making tools/ look more like kernel source code.
