ec93365612 Initial addition of tmpfs, an efficient memory file-system. This project 
was developed as part of Google's Summer of Code 2005 program.  This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*.  Therefore, it is disabled by
default in all kernels.  However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

OK'ed by my project mentor, William Studenmund (wrstuden@).

3fd1802e62 Move the MI printing of `copyright' to the MD cpu_startup() code 
where the printing of `version' is already performed.
This has the benefit of allowing the copyright to be available
via dmesg(8) on platforms which need the `msgbuf' to be setup
in cpu_startup() before printed output is remembered.

a076957818 Convert the PMAP_PREFER() macro from two arguments (offset and hint) 
to four (adding size and direction).

In order for topdown uvm to be an option on ports using PMAP_PREFER,
they will need to "prefer" lower addresses if topdown is being used.
Additionally, at least one port also needs to know the size.
