From af0b06e726242516da9df5071e4e058f949f2240 Mon Sep 17 00:00:00 2001
From: Laura Abbott <labbott@redhat.com>
Date: Thu, 5 Jul 2018 14:39:20 -0700
Subject: [PATCHv2] treewide: Rename HOSTCFLAGS -> KBUILD_HOSTCFLAGS
To: Masahiro Yamada <yamada.masahiro@socionext.com>
To: Josh Poimboeuf <jpoimboe@redhat.com>
To: Jiri Olsa <jolsa@kernel.org>
Cc: linux-kbuild@vger.kernel.org
Cc: linux-kernel@vger.kernel.org
Cc: Robin Jarry <robin.jarry@6wind.com>
In preparation for enabling command line CFLAGS, re-name HOSTCFLAGS to
KBUILD_HOSTCFLAGS as the internal use only flags. This should not have any
visible effects.
Signed-off-by: Laura Abbott <labbott@redhat.com>

v2: Dropped name change for individual files (still CHOSTFLAGS_foo)
