        src/sys/compat/netbsd32: netbsd32_sysctl.c

Log Message:
Handle vm.maxaddress in compat_netbsd32(8)

Return VM_MAXUSER_ADDRESS32 instead of the 64-bit specific address.

Use CTLTYPE_INT instead of CTLTYPE_LONG in order to retain the same integer
type between 64-bit native kernel and 32-bit emulated program.

There probably should be CTLTYPE_LONG32 available for this purpose.

On NetBSD/i386:
vm.maxaddress=bfeff000

On NetBSD/amd64:
vm.maxaddress=7fbfdfeff000

On NetBSD/amd64 running i386 program:
vm.maxaddress=fffff000

A 32-bit program on the 64-bit kernel can use larger user space, this
difference is on purpose and expected.
