No need to set it to 32768.

If you just remove the 'CONFIG_DEFAULT_MMAP_MIN_ADDR=65536' then this
symbol will be 32768.

So your patch would become:

diff --git a/arch/arm/configs/mxs_defconfig b/arch/arm/configs/mxs_defconfig
index ccdb635..4edcfb4 100644
--- a/arch/arm/configs/mxs_defconfig
+++ b/arch/arm/configs/mxs_defconfig
@@ -34,7 +34,6 @@ CONFIG_NO_HZ=y
 CONFIG_HIGH_RES_TIMERS=y

 CONFIG_AEABI=y
-CONFIG_DEFAULT_MMAP_MIN_ADDR=65536
