From 32cad1ffb81dcecf6f4a8af56d6e5892682839b1 Mon Sep 17 00:00:00 2001 From: Philippe Mathieu-Daudé Date: Tue, 3 Dec 2024 15:20:13 +0100 Subject: include: Rename sysemu/ -> system/ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Headers in include/sysemu/ are not only related to system *emulation*, they are also used by virtualization. Rename as system/ which is clearer. Files renamed manually then mechanical change using sed tool.
