d586688437 In fdcretry(), set the state to DOSEEK rather than SEEKCOMPLETE before
retrying the operation.  Fixes disk_unbusy() imbalance and really seems
like the right thing to do in case it was the seek that failed.  Takes
care of PR #1985.  Patch from John F. Woods <jfw@jfwhome.funhouse.com>

5b39541e48 New generic disk framework. Highlights:
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

74e1e47aeb fixed my own pr 1758 -- the floppy drive motor was not being turned off
at halt time, especially if a floppy was mounted. Added a shutdown hook
to turn off the motor. Per a request by mycroft, the cookie from the hook
is saved in a new member I added to the fd_softc structure.

72805df917 Various changes from John Kohl and me:
Map kernel stacks only at unique addresses.
Use one TSS per process.
Add sysarch calls for modifying IOPL and the I/O permission bitmap.
Add a compacting GDT entry allocator, for TSS and LDT selectors.
Enable modifying %fs and %gs with PT_SETREGS.
Sanitize various bits of code.

9fc36ab1a4 * Don't scroll by setting the CRT start address when in graphics mode, and

* Maintain keyboard state locally per VT. This makes sense, enables switches
  between VTs with different kbd states, and aids Linux VT emulation.
