This has been obsoleted by the root= commandline and the rdev utility
for many, many years.  People who still depend on this will surely
have a copy of the rdev utility around, the rest of the world gets rid
of another piece of buildhost-dependent data in the build. Thanks to
Paul Bolle for the build.c cleanup.

Impact: obsolete feature removal

The zImage kernel format has been functionally unused for a very long
time.  It is just barely possible to build a modern kernel that still
fits within the zImage size limit, but it is highly unlikely that
anyone ever uses it.  Furthermore, although it is still supported by
most bootloaders, it has been at best poorly tested (or not tested at
all); some bootloaders are even known to not support zImage at all and
not having even noticed.

Also remove some really obsolete constants that no longer have any
meaning.

Correct a comment in arch/i386/boot/build/tools.c; we now build the
kernel from only two components instead of three, since the boot
sector has been integrated in the setup code.

This patch hooks the new x86 setup code into the Makefile machinery.  It
also adapts boot/tools/build.c to a two-file (as opposed to three-file)
universe, and simplifies it substantially.

Variable "c" was declared as an unsigned int, but used in:

125  		for (i=0 ; (c=read(fd, buf, sizeof(buf)))>0 ; i+=c )
126  			if (write(1, buf, c) != c)
127  				die("Write call failed");

(akpm: read() can return -1.  If it does, we fill the disk up with garbage).

Remove some of the unnecessary differences between arch/i386 and
arch/x86_64.  This patch fixes more whitespace issues, some miscellaneous
typos, a wrong URL and a factually incorrect statement about the current
boot sector code.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
