device at config_found() time, so we can remove all of the stuff from
device_register() that does it, leaving only the @pci case to fix that
up (similar situation with ACPI on ARM and x86).
Adapt the boot device matching code to use the devhandle from the
device_t rather than the previous mechanism, and add some comments
explaining what's going on and some assertions to validate the
comments.
Collapse the sun4v vdsk boot device detection into the normal "sd"
case because it's almost identical to the normal "sd" case anyhow.
Assembler codes generated by GCC are identical with that of our local
fix in rev 1.26 for 32-bit processors, and no significant changes for
64-bit processors also.

rs6000: Fix cpu selection w/ isel (PR100108)
There are various non-IBM CPUs with isel as well, so it is easiest if we
just don't consider that flag here (it is not needed).

* config/rs6000/rs6000.c (rs6000_machine_from_flags): Do not consider
OPTION_MASK_ISEL.
DMA buffer. Also, when the buffer is already freed, do not call
bus_dmamap_unload(9) (no resource leaks with this change).
Otherwise, MMU fault occurs for some bus_dma(9) implementations.
With this fix, X550-T1 and X540-T1 work fine on alpha (at least
DS10 with PCI-PCIe reverse bridge).
Discussed with msaitoh. Thanks!
- Define various new AFMT_*. These are not returned as supported
formats by SNDCTL_DSP_GETFMTS, because it would be very silly to
have Vorbis in the kernel.
- Implement PLAYTGT and RECSRC. For each NetBSD audio device
we only return one playback and recording source, "primary".
- Return preferred channel configuration in capabilities.
Either DSP_CH_STEREO, DSP_CH_MONO, or DSP_CH_MULTI
depending on the current hardware format.
- SNDCTL_DSP_HALT_* simply flushes the audio device.
ncurses refuses to paint pads if the height argument extends beyond
the bounds of the screen. it's probably not good for our curses either.
libcurses wresize() refuses to resize a pad beyond the bounds of the
screen even if it was created with a larger size. this is probably
a bug.

In QEMU with an ac97 audio device, "inputs" is the first pane,
which is significantly less important especially when you don't
have input in QEMU most of the time.
in order to make both framebuffer and serial consoles happy.
Also, change TERM from vt220 to vt100 for console and constty
in accordance with other ports.
on arm64eb resuming vi(1) would often crash. in makech(), the 'csp'
variable is either set to current window data, or a local stack
variable's address '&blank'. the window data has many lines of info
stored, and 'csp++' is used per line here. unfortunately, a case
existed where 'csp++' operated on csp initialised from '&blank' which
eventually crashes when, on my display with 160 columns and 'csp + 155'
exceeds the mapped stack and crashes.
match the '!_cursesi_screen->curwin' conditional that initialises csp,
and avoid csp++ here. assert() that csp != &blank in both places that
modify csp.
thanks to jdc@ and mlelstv@.
XXX: possibly also should avoid the putch() here as well.
