configname: CONFIG_CPU_HIGH_VECTOR

Linux Kernel Configuration
└─>Select the High exception vector
In linux kernel since version 2.6.21 (release Date: 2007-04-25)  
Say Y here to select high exception vector(0xFFFF0000~).
The exception vector can vary depending on the platform
design in nommu mode. If your platform needs to select
high exception vector, say Y.
Otherwise or if you are unsure, say N, and the low exception
vector (0x00000000~) will be used.
