77abd102b7 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

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.

03fa08025b Major update: Many changes from Matthias Pfaller.
* conf/DEFAULT: new file, default install kernel
* conf/INSTALL: +MSDOSFS, +NO_INLINE_SPLX, +RD_SIZE=2mb, +scn4/5
* conf/KLONDIKE: cosmetic changes
* conf/STEELHEAD: cosmetic changes
* conf/files.pc532: rd got a file of it's own
* dev/lpt.c: changes to support lower interrupt latency, packet input/output
  is now done at spl0
* dev/ncr.c: changes to support the most recent atari version of the ncr5380
  driver
* dev/ncr5380.c, dev/ncr5380reg.h: upgraded to most recent atari version,
  memcpy -> bcopy.
* dev/rd.c: ramdisk driver
* dev/scn.c: by patching scndefaultrate, the kernel's default baud rate can
  be changed with gdb
* include/psl.h: struct iv now protected by !LOCORE && _KERNEL
  inlining of splx can be prevented with new kernel option NO_INLINE_SPLX
  splx_di is like splx but leaves processor interrupts disabled
* pc532/autoconf.c: cosmetic changes
* pc532/conf.c: with rd entries
* pc532/intr.c: changes to support splx_di
* pc532/locore.s: ramdisk is no longer initialized
  not splx, but rett is now used to reenable CPU interrupts when leaving the
  interrupt service routine. This is necessary to prevent recursive interrupts.
* pc532/sys_machdep.c: memcpy -> bcopy
* pc532/mem.c: moved ramdisk to dev/rd.c
* stand/Makefile: boot is now loaded at 0x3eb800 instead of 0x363800
  Use current form of libsa and libkern.
* stand/inflate.c: emit twiddle every 8k and not every 1k
* stand/rd.c: ramdisk starts at 0x288000
