Support CPU microcode loading via cpuctl(8).
Implemented and enabled via CPU_UCODE kernel config option
for x86 and Xen Dom0.
Tested on different AMD machines with different
CPU families.

ok wiz@ for the manpages
ok releng@
ok core@ via releng@

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

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.

Per existing x86 GENERIC kernels, add:
#options BUFQ_READPRIO
options BUFQ_PRIOCSCAN
to Xen kernels.

remove iic, I fixed the i2c code

Enable an iic(4) device to prevent a linker warning.

Sync with HEAD. Most notably: uvm/pmap work done by rmind@, and MP Xen
work of cherry@.

No regression observed on suspend/restore.

Attach amdtemp(4) at pchb(4) instead of in place of pchb(4).

Should fix PR#45268.

Enable balloon(4) for Xen kernels.

ok bouyer@; shortly discussed on port-xen@.

sync with head

Large rewrite of the balloon driver. This one:

- turns balloon into a driver that attaches to xenbus(4). This allows to
disable the functionality either at compile time or boot time via
userconf(4). Driver can implement detach or pmf(9) hooks if deemed
necessary.

- keeps Cherry's locking model, but simplify it a bit. There is now
only one target value serialized inside balloon, we do not feedback
alternative value to Xenstore (clients are not expected to see its value
evolve behind their back, and can't do much about that either)

- implements min threshold; this is an admin-settable value that tells
driver to "not balloon below this threshold." This can be used by domain
to keep memory reservations, useful if activity is expected in the near
future.

- in addition to min threshold, the driver implements internally a
safeguard value (uvmexp.freemin + 1MiB), so that admin cannot
inadvertently set min to a very low value forcing domain into heavy
memory pressure and swapping.

- create the sysctl(8) kern.xen.balloon tree. 4 nodes are actually present
(values are in KiB):
   - min: (rw) an admin-settable value that prevents ballooning below this
          mark
   - max: (ro) the maximum size for reservation, as set by xm(1) mem-max.
   - current: (ro) the current reservation for domain.
   - target:  (rw) the targetted reservation for domain.

- fix a few limitations here and there, most notably the max_reservation
hypercall, and KiB vs pages representations at interfaces.

The driver is still turned off by default. Enabling it would need more
approval, especially from bouyer@, cherry@ and cegger@.

FWIW: tested it two days long, from amd64 dom0 (with dom0 ballooning
enabled for xend), and bunch of domUs. Did not notice anything suspicious.

XXX it still has one big limitation: it cannot hotplug memory pages in
uvm(9) if they were not present beforehand. Example: ballooning above
physmem will give more pages to domain but it won't use it to serve
allocations, unless we teach uvm(9) how to handle the extra pages.

More sync fixes. And add the mbr_gpt files.

Cure sync hiccups. Code with compile errors is not really useful, heh.

Sync with HEAD. TODO before merge:
- shortcut for suspend code in sysmon, when powerd(8) is not running.
Borrow ``xs_watch'' thread context?
- bug hunting in xbd + xennet resume. Rings are currently thrashed upon
resume, so current implementation force flush them on suspend. It's not
really needed.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

hid_get_data() does not work if the size of data is less than
a byte and crosses a byte boundary, and it always returns a

hdaudio(4) is a standards-compliant driver for High Definition Audio.
It will replace azalia(4) after testing.
To use, comment out azalia in your kernel configuration and uncomment the
hdaudio and hdafg lines so it reads:
hdaudio*        at pci? dev ? function ?
hdafg*          at hdaudiobus?
You should also:
cd /dev
sh MAKEDEV audio

Switch on hdaudio(4)

Refer to hdaudio as 'High Definition Audio', not
'Intel High Definition Audio' as many vendors implement the HD audio spec.

hdaudio(4) is a standards-compliant driver for Intel High Definition Audio.

Add Intel SpeedStep and AMD PowerNow! support in Xen dom0. MSR operations
are now compiled in by default.

Note that MSR support in Xen depends on its version. rdmsr() should always
succeed, but wrmsr() to certain registers can end in a NOOP. In that case,
the error will be logged (see xm dmesg).

Setting CPU frequency (SpeedStep) requires Xen 3.3 with the option
cpufreq="dom0-kernel" passed down to hypervisor during boot.

Compiled and tested for SpeedStep under i386 for XEN3_DOM0 and XEN3PAE_DOM0
by jym@. amd64 was tested by Joel Carnat.

Revert for DOM0 as well at request of Christoph Egger.
I guess this bootstatic stuff is supposed to play nicely with dhcp,
but it still doesn't for me. I suspect it's due to misdetecting the bootdev.

Comment out NFS_BOOT_BOOTSTATIC. There no use having it in the default
kernel as it needs manual configuration anyway. Also, if it's enabled
but no static options given, then the kernel will happily configure the
interface as INADDY_ANY and not even try to use DHCP.

Remove GENERIC.local from the repository

Make all the kernels that currently include their corresponding GENERIC.local

After doing this, remove the GENERIC.local files from the repository so that
the user will not see modified files during updates, and local changes to
them cannot end up in the repository by mistake.

Discussed in tech-kern@ earlier this month.  No strong objections.

Get rid of arch/xenamd64, step 1: empty xenamd64/conf
- move xenamd64/conf/std.xen to amd64/conf/
- define arch to amd64 amd64/conf/std.xen, and i386 in xen/conf/std.xen
  (machine is xen)
- enclose content of amd64/conf/files.amd64 and i386/conf/files.i386 in
  ifndef xen/endif, so it can be transparently inclued for xen kernels
- support MACHINE_ARCH=x86_64 in xen/conf/Makefile*
