Subject: [PATCH 4.2 210/258] MIPS: CPS: #ifdef on CONFIG_MIPS_MT_SMP rather than CONFIG_MIPS_MT
Date: Sat, 17 Oct 2015 18:58:43 -0700 [thread overview]
Message-ID: <20151018014739.942301287@linuxfoundation.org> (raw)
In-Reply-To: <20151018014729.976101177@linuxfoundation.org>
4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paul Burton <paul.burton@imgtec.com>
commit 7a63076d9a31a6c2073da45021eeb4f89d2a8b56 upstream.
The CONFIG_MIPS_MT symbol can be selected by CONFIG_MIPS_VPE_LOADER in
addition to CONFIG_MIPS_MT_SMP. We only want MT code in the CPS SMP boot
vector if we're using MT for SMP. Thus switch the config symbol we ifdef
against to CONFIG_MIPS_MT_SMP.
