Subject: [PATCH 4.4 15/33] mm: hide a #warning for COMPILE_TEST
Date: Wed, 21 Feb 2018 13:44:58 +0100	[thread overview]
Message-ID: <20180221124410.439521900@linuxfoundation.org> (raw)
In-Reply-To: <20180221124409.564661689@linuxfoundation.org>

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@arndb.de>

commit af27d9403f5b80685b79c88425086edccecaf711 upstream.

We get a warning about some slow configurations in randconfig kernels:

  mm/memory.c:83:2: error: #warning Unfortunate NUMA and NUMA Balancing config, growing page-frame for last_cpupid. [-Werror=cpp]

The warning is reasonable by itself, but gets in the way of randconfig
build testing, so I'm hiding it whenever CONFIG_COMPILE_TEST is set.

The warning was added in 2013 in commit 75980e97dacc ("mm: fold
page->_last_nid into page->flags where possible").
