machine-dependent cookie of type isa_chipset_tag_t, which is also defined

c132a81557 as per cgd: 
temporarily revert bus config order back to isa->eisa->pci
	until port allocation/accounting is ready (XXX).

	works around problem of the if_ep driver's probe function trashing
	an adaptec 2940 if the BIOS maps it in at port 0xf000.  (the
	BIOS on my new P166 does this, ... the BIOS on my P133's does not).
	without this the P166 system will reset as soon as spl0() is called
	(autoconf.c) making it impossible to install the OS.

da3136aba8 modify these to provide a new, better-specified PCI interface 
(soon to be documented on mailing lists; eventually in section 9 manual
pages), most importantly:
	(1) support interrupt pin swizzling on non-i386 systems with
	    PCI-PCI bridges (per PPB spec; done, but meaningless, on i386).
	(2) provide pci_{io,mem}_find(), to determine what I/O or memory
	    space is described by a given PCI configuration space
	    mapping register.
	(3) provide pci_intr_map(), pci_intr_string(), and
	    pci_intr_{,dis}establish() to manipulate and print info about
	    PCI interrupts.
	(4) deprecate the pci_map_* functions, and provide them only
	    as compatibility interfaces (in pci_compat.c) which will
	    eventually go away, implemented as wrappers around
	    the functions described above.
	(5) make pci functions take as an argument a machine-dependent
	    cookie, to allow more flexibility in implementation.

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.
