Please leave __res1 alone. so:
            unsigned long simd:4; /* Advanced SIMD */ 
-           unsigned long __res0:8;
+           unsigned long __res0:4;
+           unsigned long gic:4; /* GIC support */
 
            unsigned long __res1;

Also note that in the ARMv8 this field is just called "gic", so I have
done the same, please do it that way otherwise when gic vN adds a new
sysreg we'll just have to rename the field.
