From d6289f36aa7d5893d091a7a0c67eee7798719f03 Mon Sep 17 00:00:00 2001 From: Cao jin Date: Fri, 16 Mar 2018 16:49:44 +0800 Subject: x86/build: Don't pass in -D__KERNEL__ multiple times Some ..cmd files under arch/x86 are showing two instances of -D__KERNEL__, like arch/x86/boot/ and arch/x86/realmode/rm/. __KERNEL__ is already defined in KBUILD_CPPFLAGS in the top Makefile, so it can be dropped safely.
