Enable the FIFO on enhanced floppy controllers. This reduces the
number of dma overruns/underruns for systems under heavy dma load.
As a side effect, broken enhanced floppy controllers that sometimes
don't detect dma overruns/underruns will give less errors.

Make FDC_DEBUG a supported option.

Hide the bogus FDC ``chip type'' display behind a (mostly) undocumented
option, since people started to trust the bogus claim. Once we're going
to handle 2.88 MB controllers, we have to redo the chip detection, by
now just leave it hidden.

Removed unused #includes.

Don't include <sys/ioctl.h> in the kernel. Stage 1: don't include
it when it is not used. In most cases, the reasons for including it
went away when the special ioctl headers became self-sufficient.

Don't #include <sys/fcntl.h> in <sys/file.h> if KERNEL is defined.
Fixed everything that depended on getting fcntl.h stuff from the wrong
place. Most things don't depend on file.h stuff at all.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.

Boy, I'm glad we're not using sup anymore. This update would have been

Disabled half-baked disk statistics support. It didn't actually generate
statistics, so it just wasted scarce disk table slots and screen space.

Fix the broken EOF handling in the floppy driver. The most obvious
appearance of this bug was the malfunctioning -M option in GNU tar (it
worked only by explicitly specifying -L).

isa_dmadone() needs more parameters than are available, so temporarily

about panics for fake parameters. Untested.
