68c1eb1215 pte.h: Add the VADDR(pdi,pti) macro to construct virtual address from 
page dir+table index.
pmap.h: remove NUPDE, it was wrong and not used.  Sanitize KSTKPTEOFF.
vmparam.h: Calculate virtual addr from PDI+PTI from pmap.h rather than
using magic math.  Remove UPDT, not used.

f4c626074b Fixed a bug introoduced in the previous change. ISA device memory was 
mapped to semi-random place(s) depending on the content(s) of physical
address 0xA0000.  This was fatal at least on my system with a some
memory-mapped devices.  Console syscons somehow wasn't affected.  It
bogusly hardcodes the address.  Sigh.

e597b4972e - add apm to the GENERIC kernel (disabled by default), and add some comments 
regarding apm to LINT
- Disabled the statistics clock on machines which have an APM BIOS and
  have the options "APM_BROKEN_STATCLOCK" enabled (which is default
  in GENERIC now)
- move around some of the code in clock.c dealing with the rtc to make
  it more obvios the effects of disabling the statistics clock

0513ce7f75 Use PCB_SAVEFPU_SIZE instead of a too-small size in savectx(). This 
bug only affected FPU emulators.  It might have caused bogus FPU states
in core dumps and in the child pcb after a fork.  Emulated FPU states
in core dumps don't work for other reasons, and the child FPU state
is reinitialized by exec, so the problem might not have caused any
noticeable affects.

Cleaned up #includes.

1dce4e5d60 Add a lock for DMA Channels to prevent two devices from using the same DMA 
channel at the same time.  The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.

Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed

ef9805a3c8 Moved rtcin() to clock.c. 
Always delay using one inb(0x84) after each i/o in rtcin() - don't
do this conditional on the bogus option DUMMY_NOPS not being defined.
If you want an optionally slightly faster rtcin() again, then inline
it and use a better named option or sysctl variable.  It only needs
to be fast in rtcintr().
