 *	(for the flags, though, only these flags are passed to the BIOS;
 *	the remainder come from the flags register at the time of the call:
 *	(PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
 *
 *	Fills in *regs with registers as returned by BIOS.

fda7345c98 re-implement BIOS trampoline as a more general-purpose, reusable trampoline. 
calling interface (via a grapple in locore.s) is:
/*
 * void bioscall(int function, struct apmregs *regs):
 * 	call the BIOS interrupt "function" from real mode with
 *	registers as specified in "regs"
 *	(for the flags, though, only these flags are passed to the BIOS;
 *	the remainder come from the flags register at the time of the call:
 *	(PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
 *
 *	Fills in *regs with registers as returned by BIOS.
 */

still some generalization to do (moving this to a better named location,
cleaning up #if tests from NAPM > 0 to something else to allow easy
sharing by other drivers)

Thanks to Charles Hannum for complaining about the previous BIOS grapple
and inspiring me to hack this one together.

698844254e A few simple changes: 
- Use an extent map to manage the ISA memory "hole", much like
	  how i/o port space is manged with an extent map.  Do the actual
	  accounting in bus_mem_{,un}map().

	- When creating the ioport and iomem extent maps, pass the
	  EX_NOBLOB flag, which tells the extent map code to disallow
	  fragmenting of regions.  This will make it easier to catch
	  simple i/o and memory mapping bugs (like the if_ed.c bug I just
	  fixed) in the future.

	- In bus_mem_map(), a chunk of code was indented using spaces.
	  Make the indentation use tabs.

	- In bus_io_unmap(), fix the format passed to printf().

8c2f15c6fc New implementation of bus_io_{,un}map() for the i386. Details: 
- A fixed extent map (statically allocated descriptor storage) is
	  created in init386(), just before the call to consinit().  The
	  fixed descriptor storage has enough room for 8 region entires,
	  which is plenty for early initialization, but doesn't chew up
	  that much memory.

	  This extent map (ioport_ex) manages the i386 i/o port
	  space (0x0 - 0xffff).

	- Just before the call to configure() in cpu_startup(), a
	  flag is set which notifies the bus_io functions that it is
	  safe to use malloc() to allocate descriptor storage, in the
	  event that more than 8 regions are needed.

	- bus_io_map() attempts to allocate the specified region from
	  ioport_ex.  If the allocation succeeds, the io handle is
	  filled in.  If the allocation fails, it is implied that
	  something else is already using that io space, and an
	  error condition is returned.

	- bus_io_unmap() frees a region previously allocated from
	  ioport_ex in bus_io_map().  If the free fails, a warning
	  is printed on the conole.

These changes implement "port accounting".  This is required for
proper autoconfiguration on the i386 port, and makes dealing with,
among other things, PCMCIA io mappings _much_ easier.

0edf3579f4 Revert last change. 
Changing types from unsigned {long,short} to u_int{32,16}_t causes problems
in a lot of userlevel code because those types aren't defined when machine/
endian.h is included.  And IMO including sys/types.h in machine/endian.h
is clearly wrong.

XPG4.2 defines new types in_addr_t and in_port_t for the {h,n}to{n,h}{l,s}
functions.  But we don't have time to figure out the implementation issues
given the current release schedule.

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.
