While here, rename one of the bus_space_handle_ts
to be be descriptive of its function.
Fixes crash caused by uninitialized bus_space_tag_t
discovered by Paul Goyette.
bus_space_tag_create(9), and bus_space_tag_destroy(9). Use
bus_space_is_equal(9) throughout the kernel to compare
bus_space_tag_t's. Tested on i386 and on sparc64.
pcdisplay.c: #if 0 some code that compares two bus_space_tag_t's
in order to see if pcdisplay0 is console. It does not seem to
be helpful to compare the tags; maybe the author intended to
compare some other bus property?
MI code should not compare an opaque type such as bus_space_tag_t!
handler! Stops a crash on the HP Pavilion N3270.
Cosmetic: sc->ih is a pointer, so set to NULL instead of 0. Compare
with NULL instead of testing truth.
especially on RTL8019AS which is also used for non-ISA local bus of
embedded controllers and some m68k machines like atari and x68k.
* move RTL8019 probe and attach code from each bus attachment
to MI ne2000_detect() and ne2000_attach()
* change a method for backend and attachment to specify 8 bit mode
to use a new sc->sc_quirk member, instead of sc->sc_dmawidth
* handle more NE2000 8 bit mode specific settings, including
bus_space(9) access width and available size of buffer memory
* add a function to detect NE2000 8 bit mode
(disabled by default, but enalbed by options NE2000_DETECT_8BIT
to avoid possible regression on various ISA clones)
* fix ipkdb attachment accordingly (untested)
Tested on two NE2000 ISA variants (RTL8019AS and another clone named UL0001)
in both 8 bit and 16 bit mode on i386. "Looks good" from nonaka@.

and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.
Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.
Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.
bus:
1 Add isadetach() for detaching the ISA bus, and add some helper
routines that release resources held for ISA DMA.
2 In isachilddetached(), forget references to child devices.
While I am here, change ISA_DMA_DRQ_ISFREE(...) == 0 to the simpler
expression, !ISA_DMA_DRQ_ISFREE(...).
partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.
No objections on tech-userlevel@.
corresponding attimer(4) resource is not perpetually busy: now it
is possible to detach and to reattach pcppi(4). Make attimer(4)'s
device-detachment hook return EBUSY if pcppi(4) is still attached, so
that pcppi(4) cannot end up with a dangling pointer to attimer(4).
