276df218b9 Allow PowerMac systems to be booted from an FDT as well as Open Firmware.
This is not complete yet: the gem(4) interface on my laptop seems to
disappear from the PCI bus as a result of quiescing Open Firmware in the
boot loader.

140e744269 Remove MODULES_OVERRIDE="" and WITHOUT_MODULES="ahc" from armv6 configs.
These are left over from long ago when there was no way to load modules
on early armv6 platforms, and when there was a build problem with ahc
that has long since been fixed, and they just keep getting copy-pasted
into new configs.

bc0ad9a99d Fix Ivy Bridge+ MEM_UOPS_RETIRED counters
The MEM_UOPS_RETIRED actually work the same way as the Sandy
Bridge counters, but the counters were documented in a different
way and that seemed to cause the Ivy Bridge counters to be
implemented incorrectly.  Use the same counter definitions as
Sandy Bridge.  While I'm here, rename the counters to match
what's documented in the datasheet.

9e60f3acd2 Fix Sandy Bridge+ hwpmc branch counters
On Sandy Bridge and later, to count branch-related events you
have to or together a mask indicating the type of branch
instruction to count (e.g. direct jump, branch, etc) and a bits
indicating whether to count taken and not-taken branches.  The
current counter definitions where defining this bits individually,
so the counters never worked and always just counted 0.

Fix the counter definitions to instead contain the proper
combination of masks.  Also update the man pages to reflect the
new counters.

3e096b705c Change the name of the dmtimer pps device from /dev/ppsN to /dev/dmtppsN.
ntpd is hard-coded to use /dev/ppsN, and typically when multiple PPS sources
are available the sysadmin will symlink the right one(s) to /dev/ppsN, so
it's best to not usurp those names directly.

aa14e9b7c9 Reimplement support for userland core dump compression using a new interface
in kern_gzio.c. The old gzio interface was somewhat inflexible and has not
worked properly since r272535: currently, the gzio functions are called with
a range lock held on the output vnode, but kern_gzio.c does not pass the
IO_RANGELOCKED flag to vn_rdwr() calls, resulting in deadlock when vn_rdwr()
attempts to reacquire the range lock. Moreover, the new gzio interface can
be used to implement kernel core compression.

This change also modifies the kernel configuration options needed to enable
userland core dump compression support: gzio is now an option rather than a
device, and the COMPRESS_USER_CORES option is removed. Core dump compression
is enabled using the kern.compress_user_cores sysctl/tunable.

4b2b0f5043 Provide a shim layer in loader to condense the Open Firmware device tree to

using Open Firmware at runtime. The code is highly experimental and disabled

bbe493ec23 Modify the if_arge code to use a /fixed/ media mode when it's configured.
Otherwise, the initial media speed would change if a PHY is hooked up,
sending PHY speed notifications.  For the AP135 at least, the RGMII
PHY has a static speed/duplex configured and if the PHY plumbing
attaches the PHY to the if_arge interface, the first link speed change
from 1000/full will set the MAC to something that isn't useful.

This shouldn't affect any other platforms - everything I looked at is
using hard-coded speed/duplex as static, as they're facing a switch
with no PHY attached.

749cac133f Add per-port vlan support for the AR8327.
All the per-port support is really doing is applying a port visibility
mask to each of the switchports.  Everything still look like a single
portgroup (vlan id 1), but the per-port visibility mask is modified.

Whilst I'm here, also add some initial dot1q support - the pvid stuff
is doing the right thing, but it's not useful without the rest of
the VLAN table programming.

It's enough for me to be able to use the LAN/WAN port distinction
on the AP135, where there isn't (for now!) a dedicated PHY for the
"WAN" port.

Tested:

* AP135, QCA9558 SoC + AR8327 switch
