From: Lv Zheng Date: Tue, 11 Apr 2017 07:48:05 +0000 (+0800) Subject: ACPICA: Add non-linux host build support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6895baa6a64fa9499e4d11696d59b3522c527ed0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ACPICA: Add non-linux host build support _LINUX: used to detect a target build is a linux kernel/application. __linux__: used to detect a build is on a linux hosts. Thus we can see: if a linux kernel build is performed on environments other than linux hosts, __linux__ may not be defined by the compiler and _LINUX cannot cover linux kernel resident ACPICA files, as it's only defined in and hence only allows non ACPICA kernel files to correctly include aclinux.h. As a conclusion, we don't actually support such build. This patch adds -D_LINUX for ACPICA files so that kernel builds on any hosts can use unified _LINUX as a linux kernel target indication to correctly include aclinux.h.
