Subject: [PATCH v4] tools/power/acpi: Remove direct kernel source include reference
Date: Wed, 16 Nov 2016 17:27:34 +0800	[thread overview]
Message-ID: <e97ef944a00367f7024d6c92cf024df3fbf00647.1479288051.git.lv.zheng@intel.com> (raw)
In-Reply-To: <CAHp75VcyRzKPGQXB736EdvyXm9m3ShnLS3Xyrjnh7iRTE5M-uw@mail.gmail.com>

ACPICA tools trickily uses integer types, and trickily includes kernel
include directory directly, which breaks tools build for some cross
compilers.
This patch improves ACPICA tools build to make it a bit more robust in such
situation by splitting include/acpi into a separate output directory.

This patch also contains OUTPUT/srctree cleanups in order to make above fix
working for various build environments.

Fixes: e323c02dee59 ("ACPICA: MSVC9: Fix <sys/stat.h> inclusion order issue")
