Modified Files:
src/sys/arch/sparc/sparc: pmap.c
Log Message:
workaround a problem -Warray-bounds triggers but isn't a problem
in practise, as described from this old commment:
/*
* Set up pm_regmap for kernel to point NUREG *below* the beginning
* of kernel regmap storage. Since the kernel only uses regions
* above NUREG, we save storage space and can index kernel and
* user regions in the same way.
*/
