growable (stack) entries that not only grow down, but also grow up.
Have vm_map_growstack() take these flags into account when growing
an entry.
This is the first step in adding support for upward growable stacks.
It is a required feature on ia64 to support the register stack (or
rstack as I like to call it -- it also means reverse stack). We do
not currently create rstacks, so the upward growing is not exercised
and the change should be a functional no-op.

syntax. The
make buildworld
mv /usr/include /usr/include.old
make installworld
issue has been fixed a month ago in Makefile,v 1.285, and there
is no valid reason to continue to keep the wrong syntax here --
buildworld takes care of upgrading a make for you if necessary.
But if you find yourself in an environment with an old make(1)
binary that breaks on this, and this is because you attempted
to run a target other than buildworld, don't whine but try again
with -DALWAYS_CHECK_MAKE defined -- it should do the trick.
Otherwise, if you still have a problem, please report it as a
bug and attach the ``make -dl ...'' output.

migration is illustrated by the modified amd64 allocator. It uses the
amd64's direct map to avoid emphemeral mappings in the kernel's

Maintainers of other 64-bit platforms with direct maps should be able
