20060723	More Transputer instructions (pfix, nfix, opr, mint, ldl, ldlp,
		eqc, rev, ajw, stl, stlf, sthf, sub, ldnl, ldnlp, ldpi, move,
		wcnt, add, bcnt).
		Adding more SPARC instructions (andcc, addcc, bl, rdpr).
		Progress on the igsfb framebuffer used by NetBSD/netwinder.
		Enabling 8-bit fills in dev_fb.
		NetBSD/netwinder 3.0.1 can now run from a disk image :-)
20060724	Cleanup/performance fix for 64-bit virtual translation table
		updates (by removing the "timestamp" stuff). A full NetBSD/pmax
		3.0.1 install for R4400 has dropped from 667 seconds to 584 :)
		Fixing the igsfb "almost vga" color (it is 24-bit, not 18-bit).
		Adding some MIPS instruction combinations (3*lw, and 3*addu).
		The 8048 keyboard now turns off interrupt enable between the
		KBR_ACK and the KBR_RSTDONE, to work better with Linux 2.6.
		Not causing PPC DEC interrupts if PPC_NO_DEC is set for a
		specific CPU; NetBSD/bebox gets slightly further than before.
		Adding some more SPARC instructions: branches, udiv.
20060725	Refreshing dev_pckbc.c a little.
		Cleanups for the SH emulation mode, and adding the first
		"compact" (16-bit) instructions: various simple movs, nop,
		shll, stc, or, ldc.
20060726	Adding dummy "pcn" (AMD PCnet NIC) PCI glue.
20060727	Various cleanups; removing stuff from cpu.h, such as
		running_translated (not really meaningful anymore), and
		page flags (breaking into the debugger clears all translations
		anyway).
		Minor MIPS instruction combination updates.
20060807	Expanding the 3*sw and 3*lw MIPS instruction combinations to
		work with 2* and 4* too, resulting in a minor performance gain.
		Implementing a usleep hack for the RM52xx/MIPS32/MIPS64 "wait"
		instruction (when emulating 1 cpu).
20060808	Experimenting with some more MIPS instruction combinations.
		Implementing support for showing a (hardcoded 12x22) text
		cursor in igsfb.
20060809	Simplifying the NetBSD/evbmips (Malta) install instructions
		somewhat (by using a NetBSD/pmax ramdisk install kernel).
20060812	Experimenting more with the MIPS 'wait' instruction.
		PCI configuration register writes can now be handled, which
		allow PCI IDE controllers to work with NetBSD/Malta 3.0.1 and
		NetBSD/cobalt 3.0.1. (Previously only NetBSD 2.1 worked.)
20060813	Updating dev_gt.c based on numbers from Alec Voropay, to enable
		Linux 2.6 to use PCI on Malta.
		Continuing on Algor interrupt stuff.
20060814	Adding support for routing ISA interrupts to two different
		interrupts, making it possible to run NetBSD/algor :-)
20060814-15	Testing for the release.
