at boot.
Add a ksyms_mod_foreach() function to iterate a callback function over the
set of elf symbols for a specific module (netbsd included).
Add kern_ctf.c and mod_ctf_get() to allow the retrieval and decompression
of CTF sections for a specific module.
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@.

on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.
The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.
into subr_device.c instead of having them in subr_autoconf.c.
Since none of the copyrights in subr_autoconf.c really match the
history of device accessors, I took the liberty of slapping (c)
2006 TNF onto subr_device.c.
#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.
for the patches!
I've lightly tested the basics: create cgd0 on vnd0d, initialize with
zeros, newfs /dev/cgd0a, mount, copy files on, unmount, drvctl -d
cgd0. Works fine. I also shutdown with a cgd0 configured: detached as
expected.
support, i.e. move vfs functionality to a separate module
(kern_module_vfs.c)
* make module proplist size an MI constant (now 8k) instead of PAGE_SIZE
* change some error values to something else than the karmic EINVAL
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.
Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).
Discussed on <tech-kern>, reviewed by <ad>.
