MFC 265155, 265254:

Omit from the universe build all config files tagged with #NO_UNIVERSE.

Add FDT to the VYBRID kernel.

MFC 263301

In kernel config files, it is supposed to be 'options<space><tab>' not
'options<tab><tab>', per long standing (but recently not so strictly
enforced) convention.

MFC 263245: Make all the comments '# ' and align to same column.

262950

Strip arm/conf/DEFAULTS down to just items that are mandatory for running
the architecture.

Move all the files named foo/common.c to foo/foo_common.c

Initial cut for DTS on the hl201 board.

Add commented out dts for sam9260ek as well as early printf support.

Make clock optional on uart nodes, then back it out ("I don't know what I
was thinking, but it is lame.")

Set the baud rate if it isn't 0

Make at91_soc_id() public.

Properly round at91 resource on unmapping.

Move AT91 AIC related stuff to own file.

Fix another bug in multicast filtering. i.MX uses 6 bits from MSB in
LE CRC32 for the hash value, not the lowest 6 bits in BE CRC32.

Follow r262916 with one more config file that references a renamed common.c

Remove bogus AT91 define that causes compile errors. Most of the defines
for SAM9X are going away soonish anyway (once FDT works), but until
then...

Remove all dregs of a per-thread undefined-exception-mode stack.

Rework the VFP code that handles demand-based save and restore of state.

Always call vfp_discard() on thread death.

When a thread begins life it doesn't own the VFP hardware state on any cpu.

Make undefined exception entry MP-safe.

MFC r257549, r261642

Don't create a distinct free page pool for segregating allocations that are
accessed through the direct map unless the kernel configuration actually
includes a direct map. Only a few configurations do, and for the rest the
unnecessary free page pool is a small pessimization.

Remove the ARM_USE_SMALL_ALLOC option and code related to it.

MFC r261570, r261572

Revert r260440 (add USB_HOST_ALIGN to all configs, it's only needed for
platforms with a 64-byte cacheline size).

Add option USB_HOST_ALIGN=64 for all SoCs that have 64 byte cache lines.

Fix the name of the dts file for the HL201...

When mapping an address, the bsh needs the same offset we do for other things.

Add explicit depends on bus_if.h and device_if.h to avoid a
chicken and egg problem in some compilation environments.

Switch to using PAs rather than VAs for the addresses we map for
devices. This is a nop, except for what's reported by atmelbus for the
resources.

Comment cleanups. Move things around for diff reduction against FDT work.

MFC r260440, r260441, r260447, r260490, r260493

Add option USB_HOST_ALIGN to configs that contain 'device usb'.

Update dts files of Cubieboard1,2 to use 1GB memory.

Add a function to print the contents of the static device mapping table,

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Back out r253779 & r253786.

Decouple yarrow from random(4) device.

* Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option.
The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow.

* random(4) device doesn't really depend on rijndael-*. Yarrow, however, does.

* Add random_adaptors.[ch] which is basically a store of random_adaptor's.
random_adaptor is basically an adapter that plugs in to random(4).
random_adaptor can only be plugged in to random(4) very early in bootup.
Unplugging random_adaptor from random(4) is not supported, and is probably a
bad idea anyway, due to potential loss of entropy pools.
We currently have 3 random_adaptors:
+ yarrow
+ rdrand (ivy.c)
+ nehemeiah

* Remove platform dependent logic from probe.c, and move it into
corresponding registration routines of each random_adaptor provider.
probe.c doesn't do anything other than picking a specific random_adaptor
from a list of registered ones.

* If the kernel doesn't have any random_adaptor adapters present then the
creation of /dev/random is postponed until next random_adaptor is kldload'ed.

* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
system wide one.

Strip trailing whitespace.

Remove pty(4) from our kernel configurations.

As of FreeBSD 8, this driver should not be used. Applications that use
posix_openpt(2) and openpty(3) use the pts(4) that is built into the
kernel unconditionally. If it turns out high profile depend on the
pty(4) module anyway, I'd rather get those fixed. So please report any
issues to me.

The pty(4) module is still available as a kernel module of course, so a
simple `kldload pty' can be used to run old-style pseudo-terminals.

Change all the sample kernel configurations to use
NFSCL, NFSD instead of NFSCLIENT, NFSSERVER since
NFSCL and NFSD are now the defaults. The client change is
needed for diskless configurations, so that the root
mount works for fstype nfs.

Adjust style (following the already existing rules) for the newly
introduced option DEADLKRES.

Reported by: danfe, julian, avg

Add the options DEADLKRES (introducing the deadlock resolver thread) in
the 'debugging' section of any HEAD kernel and enable for the mainstream
ones, excluding the embedded architectures.
It may, of course, enabled on a case-by-case basis.

- Use "device\t" and "options \t" for consistency.

Change over the usb kernel options to the new stack (retaining existing
naming). The old usb stack can be compiled in my prefixing the name with 'o'.

Include std.ixp425 for "cpu" and comment out duplicate memory map
options. Using the already included std.avila is not considered
to be entirely right (and the options slightly differ) but the best
match we currently have. Upcoming work should fit better.

Reorder another variable to match the layout of other configs.

enable use of modules but disable them by adding MODULES_OVERRIDE=""
in each config file until we can sort out issues in the modules tree

Add arm/conf/DEFAULTS and populate it with:
machine arm
device mem
options GEOM_BSD
options GEOM_MBR

Remove the first two from all kernel configuration files and
change geom_bsd and geom_mbr from standard to optional.

Commit the no-brainer parts of my space saving kernel experiments. We
don't inline the locking primitives, and only grab those parts of mii
that we really need. Other space optimizations are too agressive for
the generic file (removing all of usb, and loading it as kernel
modules).

Kernel config for the Linksys NSLU2. This is just a basic configuration,
with no support for the LED, buttons, realtime clock or flash support.
