Don't lock in the generic grab just to lock again in the specific grabs.

- Only check the ivars for direct descendants.
- A couple of whitespace fixes.
Add a new flag to /etc/ttys: onifconsole. This is equivalent to "on" if the
device is an active kernel console and "off" otherwise. This is designed to
allow serial-booting x86 systems to provide a login prompt on the serial line
by default without providing one on all systems by default.

In pmap_set_pte(), make sure to enforce ordering by inserting a memory
fence. Under system load, the CPU has been found to change the order
by which the stores are made visible. When the tag is made visible
before the other TLB values, other CPUs may use the invalid TLB values
and do bad things.

While here (i.e. not a fix) don't return errors from pmap_remove_vhpt()
to callers of pmap_remove_pte(). Those callers don't check the return
value and as such don't do what is needed to keep a consistent state.
More importantly, pmap_remove_vhpt() can't really have an error without
it indicating something unintended. Using KASSERT is therefore better.

We need nand now that the boards reference it.
Sync with (local) changes against releng/10.0/release/doc/
that were needed to fix 10.0-RELEASE release notes.

This corresponds to r43586 through r43593 of the doc/
repository.  There are no corresponding changes to the src/
repository tracking these.

Add support for displaying VPD for PCI devices via pciconf.
- Store the length of each read-only VPD value since not all values are
  guaranteed to be ASCII values (though most are).
- Add a new pciio ioctl to fetch VPD for a single PCI device.  The values
  are returned as a list of variable length records, one for the device
  name and each keyword.
- Add a new -V flag to pciconf's list mode which displays VPD data for
  each device.

Remove entries that:
 - exist in a release [1]
 - do not have a corresponding revision class

[1] This is done to make ensure for 11.0-RELEASE, we do not end
up with entries from older releases, like happened with 10.0-R.

Fix the resource information for the i2s-a node on certain G5 PowerMacs.
This is the first step needed to get the snapper codec working on those
machines.
The second step is to enable the corresponding I2S device and its clock.

Tested on machines where the snapper codec was already working, a G4 PowerBook
and a PowerMac9,1 with a Shasta based macio.
The PowerMac7,2/7,3 with a K2 based macio can now also play sound.
