[PATCH] ARM: imx_v6_v7_defconfig: Select CONFIG_HIGHMEM

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

Booting a mx6q wandboard with 2GB of RAM we see the following on boot:

Booting Linux on physical CPU 0x0                                               
Linux version 3.12.0-next-20131112+ (fabio at fabio-Latitude-E6410) (gcc version 43
CPU: ARMv7 Processor [412fc09a] revision 10 (ARMv7), cr=10c53c7d                
CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache        
Machine model: Wandboard i.MX6 Quad Board                                       
Truncating RAM at 10000000-8fffffff to -7f7fffff (vmalloc region overlap)
...

Select CONFIG_HIGHMEM to avoid the vmalloc region overlap.
