>Description:
Since MAXDSIZ bump from 1GB to 8GB, i cannot compile a kernel anymore :

#   compile  LANFEUST/kern_resource.o
/local/src/NetBSD/tool/amd64/bin/x86_64--netbsd-gcc -mcmodel=kernel -mno-red-zone -ffreestanding -g -O2 -fno-omit-frame-pointer -Werror -Wall -Wno-main -Wno-format-zero-length -Wpointer-arith -Wmissing-prototypes -Wstrict-prototypes -Wno-sign-compare -fno-zero-initialized-in-bss -Damd64 -Dx86_64 -I. -I/local/src/NetBSD/src/sys/arch -I/local/src/NetBSD/src/sys -nostdinc -DLKM -DFFS_SNAPSHOT -DDIAGNOSTIC -DMAXUSERS=32 -D_KERNEL -D_KERNEL_OPT -I/local/src/NetBSD/src/sys/dist/ipf -c /local/src/NetBSD/src/sys/kern/kern_resource.c
/local/src/NetBSD/src/sys/kern/kern_resource.c:62: warning: integer overflow in expression

>How-To-Repeat:
cd src && ./build.sh -Uu -m amd64 kernel=LANFEUST
