20051011        Passing -A as the default boot arg for CATS (works fine with
                OpenBSD/cats).
20051012	Fixing the VGA cursor offset bug, and speeding up framebuffer
		redraws if character cells contain the same thing as during
		the last redraw.
20051013	Adding a slow strd ARM instruction hack.
20051017	Minor updates: Adding a dummy i80321 Verde controller (for
		XScale emulation), fixing the disassembly of the ARM "ldrd"
		instruction, adding "support" for less-than-4KB pages for ARM
		(by not adding them to translation tables).
20051020	Continuing on some HPCarm stuff. A NetBSD/hpcarm kernel prints
		some boot messages on an emulated Jornada 720.
		Making dev_ram work better with dyntrans (speeds up some things
		quite a bit).
20051021	Automatically generating some of the most common ARM load/store
		multiple instructions.
20051022	Better statistics gathering for the ARM load/store multiple.
		Various other dyntrans and device updates.
20051023	Various minor updates.
20051024	Continuing; minor device and dyntrans fine-tuning. Adding the
		first "reasonable" instruction combination hacks for ARM (the
		cores of NetBSD/cats' memset and memcpy).
20051025	Fixing a dyntrans-related bug in dev_vga. Also changing the
		dyntrans low/high access notification to only be updated on
		writes, not reads. Hopefully it will be enough. (dev_vga in
		charcell mode now seems to work correctly with both reads and
		writes.)
		Experimenting with gathering dyntrans statistics (which parts
		of emulated RAM that are actually executed), and adding
		instruction combination hacks for cache cleaning and a part of
		NetBSD's scanc() function.
20051026	Adding a bitmap for ARM emulation which indicates if a page is
		(specifically) user accessible; loads and stores with the t-
		flag set can now use the translation arrays, which results in
		a measurable speedup.
20051027	Dyntrans updates; adding an extra bitmap array for 32-bit
		emulation modes, speeding up the check whether a physical page
		has any code translations or not (O(n) -> O(1)). Doing a
		similar reduction of O(n) to O(1) by avoiding the scan through
		the translation entries on a translation update (32-bit mode
		only).
		Various other minor hacks.
20051029	Quick release, without any testing at all.

20050408	Some minor updates to the wdc. Linux now doesn't complain
		anymore if a disk is non-present.
20050409	Various minor fixes (a bintrans bug, and some other things).
		The wdc seems to work with Playstation2 emulation, but there
		is a _long_ annoying delay when disks are detected.
		Fixing a really important bintrans bug (when devices and RAM
		are mixed within 4KB pages), which was triggered with
		NetBSD/playstation2 kernels.
20050410	Adding a dummy dev_ps2_ether (just so that NetBSD doesn't
		complain as much during bootup).
		Symbols starting with '$' are now ignored.
		Renaming dev_ps2_ohci.c to dev_ohci.c, etc.
20050411	Moving the bintrans-cache-isolation check from cpu_mips.c to
		cpu_mips_coproc.c. (I thought this would give a speedup, but
		it's not noticable.)
		Better playstation2 sbus interrupt code.
		Skip ahead many ticks if the count register is read manually.
		(This increases the speed of delay-loops that simply read
		the count register.)
20050412	Updates to the playstation2 timer/interrupt code.
		Some other minor updates.
20050413	NetBSD/cobalt runs from a disk image :-) including userland;
		updating the documentation on how to install NetBSD/cobalt
		using NetBSD/pmax (!).
		Some minor bintrans updates (no real speed improvement) and
		other minor updates (playstation2 now uses the -o options).
20050414	Adding a dummy x86 (and AMD64) mode.
20050415	Adding some (32-bit and 16-bit) x86 instructions.
		Adding some initial support for non-SCSI, non-IDE floppy
		images. (The x86 mode can boot from these, more or less.)
		Moving the devices/ and include/ directories to src/devices/
		and src/include/, respectively.
20050416	Continuing on the x86 stuff. (Adding pc_bios.c and some simple
		support for software interrupts in 16-bit mode.)
20050417	Ripping out most of the x86 instruction decoding stuff, trying
		to rewrite it in a cleaner way.
		Disabling some of the least working CPU families in the
		configure script (sparc, x86, alpha, hppa), so that they are
		not enabled by default.
20050418	Trying to fix the bug which caused problems when turning on
		and off bintrans interactively, by flushing the bintrans cache
		whenever bintrans is manually (re)enabled.
20050419	Adding the 'lswi' ppc instruction.
		Minor updates to the x86 instruction decoding.
20050420	Renaming x86 register name indices from R_xx to X86_R_xx (this
		makes building on Tru64 nicer).
20050422	Adding a check for duplicate MIPS TLB entries on tlbwr/tlbwi.
20050427	Adding screenshots to guestoses.html.
		Some minor fixes and testing for the next release.
