Rework how KERNOBJDIR functions; now it's always determined with
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile. Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.

Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Added arch/newsmips/Makefile.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

- Note that some drivers still update packet statistics in their own
way (periodical update)

Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

in the thread at tech-kern@ and tech-net@:

Redefine bpf linkage through an always present op vector, i.e.

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.

*** Summary ***

When a link-layer address changes (e.g., ifconfig ex0 link
02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor
Advertisement to update the network-/link-layer address bindings
on our LAN peers.

Refuse a change of ethernet address to the address 00:00:00:00:00:00
or to any multicast/broadcast address. (Thanks matt@.)

Reorder ifnet ioctl operations so that driver ioctls may inherit
the functions of their "class"---ether_ioctl(), fddi_ioctl(), et
cetera---and the class ioctls may inherit from the generic ioctl,
ifioctl_common(), but both driver- and class-ioctls may override
the generic behavior. Make network drivers share more code.

Distinguish a "factory" link-layer address from others for the
purposes of both protecting that address from deletion and computing
EUI64.

Return consistent, appropriate error codes from network drivers.

Improve readability. KNF.

*** Details ***

In if_attach(), always initialize the interface ioctl routine,
ifnet->if_ioctl, if the driver has not already initialized it.
Delete if_ioctl == NULL tests everywhere else, because it cannot
happen.

In the ioctl routines of network interfaces, inherit common ioctl
behaviors by calling either ifioctl_common() or whichever ioctl
routine is appropriate for the class of interface---e.g., ether_ioctl()
for ethernets.

Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In
the user->kernel interface, SIOCSIFADDR's argument was an ifreq,
but on the protocol->ifnet interface, SIOCSIFADDR's argument was
an ifaddr. That was confusing, and it would work against me as I
make it possible for a network interface to overload most ioctls.
On the protocol->ifnet interface, replace SIOCSIFADDR with
SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to
invoke SIOCINITIFADDR.

In ifioctl(), give the interface the first shot at handling most
interface ioctls, and give the protocol the second shot, instead
of the other way around. Finally, let compatibility code (COMPAT_OSOCK)
take a shot.

Pull device initialization out of switch statements under
SIOCINITIFADDR. For example, pull ..._init() out of any switch
statement that looks like this:

switch (...->sa_family) {
case ...:
..._init();
...
break;
...
default:
..._init();
...
break;
}

Rewrite many if-else clauses that handle all permutations of IFF_UP
and IFF_RUNNING to use a switch statement,

switch (x & (IFF_UP|IFF_RUNNING)) {
case 0:
...
break;
case IFF_RUNNING:
...
break;
case IFF_UP:
...
break;
case IFF_UP|IFF_RUNNING:
...
break;
}

unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and
#ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4).

In ipw(4), remove an if_set_sadl() call that is out of place.

In nfe(4), reuse the jumbo MTU logic in ether_ioctl().

Let ethernets register a callback for setting h/w state such as
promiscuous mode and the multicast filter in accord with a change
in the if_flags: ether_set_ifflags_cb() registers a callback that
returns ENETRESET if the caller should reset the ethernet by calling
if_init(), 0 on success, != 0 on failure. Pull common code from
ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(),
and register if_flags callbacks for those drivers.

Return ENOTTY instead of EINVAL for inappropriate ioctls. In
zyd(4), use ENXIO instead of ENOTTY to indicate that the device is
not any longer attached.

Add to if_set_sadl() a boolean 'factory' argument that indicates
whether a link-layer address was assigned by the factory or some
other source. In a comment, recommend using the factory address
for generating an EUI64, and update in6_get_hw_ifid() to prefer a
factory address to any other link-layer address.

Add a routing message, RTM_LLINFO_UPD, that tells protocols to
update the binding of network-layer addresses to link-layer addresses.
Implement this message in IPv4 and IPv6 by sending a gratuitous
ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD
messages on a change of an interface's link-layer address.

In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address
that is broadcast/multicast or equal to 00:00:00:00:00:00.

Make ether_ioctl() call ifioctl_common() to handle ioctls that it
does not understand.

In gif(4), initialize if_softc and use it, instead of assuming that
the gif_softc and ifp overlap.

Let ifioctl_common() handle SIOCGIFADDR.

Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels
that certain invariants on a struct route are satisfied.

In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit
about the ioctls that we do not allow on an agr(4) member interface.

bzero -> memset. Delete unnecessary casts to void *. Use
sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Simplify and make extensible the config_search() / config_found() /

which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:

Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

add NEWSMIPS_WSDISPLAYIO_GINFO ioctl to get frame buffer stride.

eliminate uvm_useracc() in favor of checking the return value of
copyin() or copyout().

uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed. however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors. most of
the callers of uvm_useracc() make the above incorrect assumption. the
rest are all misguided optimizations, which optimize for the case
where an operation will fail. we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors. since there appear to be no good uses of uvm_useracc(), we'll
just remove it.

This merge changes the device switch tables from static array to

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Rework how KERNOBJDIR functions; now it's always determined with
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile

whilst here.

branches: 1.72.2;
Add options COMPAT_20.

Add tap(4) support to a random^Wcarefully chosen set of kernel configs.
All those kernels have a line for both tun and bridge, and if either is
commented out, tap is commented out also. With the exception of i386's
GENERIC_TINY.

XXX: we _need_ some way of making this more simple.

branches: 1.70.4;
Add COMPAT_BSDPTY to the rest of the config files.

IPv4 PIM support, based on a submission from Pavlin Radoslavov posted on
tech-net@

Add "options SYSCTL_INCLUDE_DESCR" to a lot of configs, but commented
out in most of them.

Add options P1003_1B_SEMAPHORE
to all GENERIC-like kernel config files where SYSV* options were already
present (commented out if the SYSV* options are commented out).
Fix lib/25897 and lib/25898.

Add (commented out) ALTQ options to all GENERIC-like files

have pf and pflog pseudo-device (commented out).
reviewed by matt, perry, christos

ptm is now mandatory, depends on pty, and can be disabled with -DNO_DEV_PTM

Add pseudo-device ptm on all the generic flavored kernels.

branches: 1.62.2;
Switch to use MI mk48txx(4) and todr(9) for MK48T02 todclocks on newsmips.

Add options COMPAT_16.

Use wildcard for scsibus at sc0.

Add pseudo-device ksyms.

Enable options NTP, DDB and SCSIVERBOSE.

Bye Bye UCONSOLE

Make BRIDGE_IPF an option, and document it. Add it (commented) to GENERIC.
Let brconfig tell whether the bridge is using the ipfilter hook, or not.

Fix typo (responsiness -> responsiveness).

Add NEW_BUFQ_STRATEGY (disabled by default).

add SYSTRACE; approved perry.

Add one space between "#option" and "<tab>IPFILTER_DEFAULT_BLOCK"

Added (commented out) IPFILTER_DEFAULT_BLOCK.

enable USERCONF by default; it's small and extremely useful to have available.

Enable "pseudo-device clockctl" in all kernels, except
installation related kernels (INSTALL* and RAMDISK*).
This enables rc.conf(5) $ntpd_chroot to be used "out of the box"

branches: 1.47.2; 1.47.4;
Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Enable spifi SCSI.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size
requirements.

add options PIPE_SOCKETPAIR to individual kernel configs
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines

Add new RF_* options for RAIDframe bits that are no longer built by default.

While we're here, enable RAIDframe (and RAID_AUTOCONFIG) by default for
architectures that I'm comfortable can deal with it being on by default.

Also: bump the number of 'raid' devices from 4 to 8, since 4 seems to
be insufficient in practise.

Add PPPoE to all generic kernels that should be able to use it.
XXX TODO: do this for INSTALL kernels too, add sysinst support and make the
XXX needed binaries available on the ramdisk root fs.

Add a blurb to the top of all GENERIC files. This serves three purposes:
- to clarify some terminology
- to clarify the intention of the GENERIC file
- to cross-reference some useful man pages

The bridge(4) pseudo-device no longer requires the port to
__HAVE_GENERIC_SOFT_INTERRUPTS, so add it back to all GENERIC configs.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.38.6;
Comment out bridge pseudo devices from ports that don't
__HAVE_GENERIC_SOFT_INTERRUPTS. bridge(4) doesn't compile there.

Add bridge pseudo devices to GENERIC configs

branches: 1.36.2;
Standardise TCP_COMPAT_42 as commented out, grouped with other COMPAT options,
and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)

Add System V semaphore resource limits to each GENERIC file that has an
option for System V semaphores. It appears that there are no overrides
in the code and each file has the following added.

options SYSVSEM # System V semaphores
+#options SEMMNI=10 # number of semaphore identifiers
+#options SEMMNS=60 # number of semaphores in system
+#options SEMUME=10 # max number of undo entries per process
+#options SEMMNU=30 # number of undo structures in system
options SYSVSHM # System V shared memory

If anyone thinks that this is incorrect for any of these files, please
correct it.

Note - the i386 port was not forgotten. It was done separately.

Add pseudo-device vlan

Screen console works now.

Switch to wscons.

Add dmac for spifi. (commented out)

Add spifi SCSI (commented out yet).

add Tulip (tlp) at apbus

Add rnd.

don't specify number of ptys if >= 16 (current default initial number)
pty comments: normalize and g/c what is no longer relevant

move "options PULLDOWN_TEST" into sys/sys/mbuf.h (in #ifdef _KERNEL),
as it is no wthe default setting for everyone.

the reason we still use the name "PULLDOWN_TEST" while it is now default:
kame code sharing.

Moving to a default of 64 PTYs.

add PULLDOWN_TEST for all the platforms.
XXX should be moved to somewhere else when stabilized

Remove prefix construction for softdeps. Add SOFTDEP option to GENERIC.

branches: 1.22.2;
Remove the obsolete config fragments for kernel crypto, because the IPsec
crypto code is now in the kernel source tree.

branches: 1.21.2;
add stf pseudo interface (commented out due to possible security risks)

Do the "<space><tab>" thing with the RAID_AUTOCONFIG option.

Defopt 'RAID_AUTOCONFIG'. Adding 'options RAID_AUTOCONFIG' turns on
the component auto-detection and auto-configuration of RAID sets.
Also, add "#options RAID_AUTOCONFIG" to the GENERIC config files.

Nuke NKMEMCLUSTERS.

Add commented out "ident"-command

Use flags to determine PCLK rather than use unit number.

Add overlay to kernel configs.

First cut of news5000 support.
Mostly from SHIMIZU Ryo <dejiko@di.gi.charat.org>.

Add interrupt level locator and use it instead of hard-coding.

bring in content of GENERIC.v6 into GENERIC.
remove GENERIC.v6 file (as it is part of GENERIC now).

"faith" interface is commented out by default as it is not really for
general use.
IPsec items are commented out as well, though we can enable "options IPSEC"
without export-related issue ("options IPSEC" will enable authentication
portion only). We may need to think about it again.

if you have problem compiling with INET6 on archs I do not have access to,
please contact me.

XXX what to do with arch/arm32/SHARK{,.v6}?

Add commented out option SOFTDEP to all GENERIC kernels.

branches: 1.10.2; 1.10.8;
It's time to be COMPAT_14.

enable PPP_BSDCOMP, PPP_DEFLATE, PPP_FILTER, PFIL_HOOKS, IPFILTER_LOG
on the GENERIC kernels that had them commented out.
XXX: Please note, that not all the kernels have all the options defined!

branches: 1.8.4; 1.8.6;
Add (commented out) 'gre' pseudo device line. Feedback is welcome.
Inspired by Klaus Klein.

Added a (commented out) configuration line for the RAIDframe device driver.

remove options FIFO; it's now the default

Add support for NWB-231A 4-port RS-232C card.

Comment out (unnecessary) "options EXEC_AOUT".

Add commented out "options FFS_EI"

Rename NetBSD/news to NetBSD/newsmips.

Initial import of NetBSD/news.

Add examples for including the kernel crypto bits from either crypto-us
or crypto-intl, commented out, with instructions to use only one, and
adjust the prefix as necessary.

branches: 1.1.2;
kernel configuration for IPv6/IPsec. should be in GENERIC in the future.
(source code will be committed soon)

Add support for LCD-MONO framebuffer on NWS-32x0 laptop machines.

Tested on NWS-3260, which was sent from ryo@'s belongins and repaired
by me, and also tested on my NWS-3470D, including Xorg mono server.
(Note X.org server on NEWS machines requires keymap modifications)
Also add proper initialization on consinit() in NMB-253 case.

Worth to pull up to netbsd-10 and netbsd-9.

Specify -fno-unwind-tables to shrink kernel binaries.

branches: 1.47.4; 1.47.30;
bump ramdisk sizes to cope with GCC 7 bloat.

branches: 1.46.4;
clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

surf the bloat

branches: 1.44.2;
Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Bump the ramdisk size; the longer paths on the build cluster are
likely enough to put this over the edge.

remove confusing numeric locators where they are unused.

branches: 1.41.2;
Update all kernel configs mentioning WSEMUL_* but not already including
WSDISPLAY_COMPAT_USL using the following rules:
- If WSEMUL_ is commented out, add commented out out WSDISPLAY_COMPAT_USL
- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL

Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.

Now wsconscfg(8) should be able to switch VTs when expected.

Implemented after no objection from tech-kern to the following:

WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.39.2;

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

Remove unused count from pseudo-device md.

Remove unused count (invariably "4") from pseudo-device fss.

branches: 1.36.4; 1.36.6;
Changes to MEMORY_RBFLAGS option:
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)
