NetBSD/sys/arch/i386/conf/Makefile.i386
thorpej dc80cc068b Move KERNBASE to 0xc0000000, giving the kernel a more-or-less full 1G
of virtual address space, leaving userland with 3G, and update comments
to match the new reality.

We knew we were going to have to bite this bullet eventually, and there
are a couple of outstanding PRs related to this issue (9389 and 9313).
Complete solution to those PRs is going to involve some sort of run-time
decision on how large kmem_map should be, as well as changing some data
structure allocation strategies in UVM.  However, this change will at
least allow the PR submitter to simply throw resources at the problem.

# Makefile for NetBSD

# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arch/i386/conf/``machineid''
# after which you should do
# config machineid
# Machine generic makefile changes should be made in
# /sys/arch/i386/conf/Makefile.i386
# after which config should be rerun for all machines of that type.
#
# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
# IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
#
# -DTRACE compile in kernel tracing hooks
# -DQUOTA compile in file system quotas
.include <bsd.own.mk>
# DEBUG is set to -g if debugging.
# PROF is set to -pg if profiling.
