Date
This is a note to let you know that I have just added a patch titled

MIPS: CPS: #ifdef on CONFIG_MIPS_MT_SMP rather than CONFIG_MIPS_MT

to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree
which can be found at:

http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue

Subject: MIPS: CPS: #ifdef on CONFIG_MIPS_MT_SMP rather than CONFIG_MIPS_MT

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.
