82cb5c3b5b Native PCI-express HotPlug support.
PCI-express HotPlug support is implemented via bits in the slot
registers of the PCI-express capability of the downstream port along
with an interrupt that triggers when bits in the slot status register
change.

This is implemented for FreeBSD by adding HotPlug support to the
PCI-PCI bridge driver which attaches to the virtual PCI-PCI bridges
representing downstream ports on HotPlug slots. The PCI-PCI bridge
driver registers an interrupt handler to receive HotPlug events. It
also uses the slot registers to determine the current HotPlug state
and drive an internal HotPlug state machine. For simplicty of
implementation, the PCI-PCI bridge device detaches and deletes the
child PCI device when a card is removed from a slot and creates and
attaches a PCI child device when a card is inserted into the slot.

The PCI-PCI bridge driver provides a bus_child_present which claims
that child devices are present on HotPlug-capable slots only when a
card is inserted. Rather than requiring a timeout in the RC for
config accesses to not-present children, the pcib_read/write_config
methods fail all requests when a card is not present (or not yet
ready).

These changes include support for various optional HotPlug
capabilities such as a power controller, mechanical latch,
electro-mechanical interlock, indicators, and an attention button.
It also includes support for devices which require waiting for
command completion events before initiating a subsequent HotPlug
command. However, it has only been tested on ExpressCard systems
which support surprise removal and have none of these optional
capabilities.

PCI-express HotPlug support is conditional on the PCI_HP option
which is enabled by default on arm64, x86, and powerpc.

Clocks, GPIO, UART, SD card / eMMC, USB, watchdog, and ethernet are
supported. Note that the A83T contains two clusters of four Cortex-A7
CPUs, and only CPUs in first cluster are started for now.

Tested on a Sinovoip Banana Pi BPI-M3.

148ed57165 [bwn] [bhnd] initial support for using bhnd for if_bwn devices.
This is an initial work in progress to use the replacement bhnd
bus code for devices which support it.

* Add manpage updates for bhnd, bhndb, siba
* Add kernel options for bhnd, bhndbus, etc
* Add initial support in if_bwn_pci / if_bwn_mac for using bhnd
  as the bus transport for suppoted NICs
* if_bwn_pci will eventually be the PCI bus glue to interface to bwn,
  which will use the right backend bus to attach to, versus direct
  nexus/bhnd attachments (as found in embedded broadcom devices.)

The PCI glue defaults to probing at a lower level than the bwn glue,
so bwn should still attach as per normal without a boot time tunable set.

It's also not fully fleshed out - the bwn probe/attach code needs to be
broken out into platform and bus specific things (just like ath, ath_pci,
ath_ahb) before we can shift the driver over to using this.

Tested:

* BCM4311, STA mode
* BCM4312, STA mode

* Break out the 'g' phy code;
* Break out the debugging bits into a separate source file, since
  some debugging prints are done in the phy code;
* Make some more chip methods in if_bwn.c public.

This brings the size of if_bwn.c down to 6,805 lines which is now
approaching managable.

b976830308 [bwn] break out the LP PHY code into a separate file.
This (and eventually migrating the other PHY code out) is in preparation
for adding the 11n PHY.  No, the 11ac PHY (for the BCM4260 softmac part) isn't
yet open source, so we can't grow that.  Yet.

This trims ~3,700 lines of code from if_bwn.c, bringing it down to a slightly
less crazy sounding 10,446 lines of code.

fd868a25a8 Change the fdt_static_dtb.S dependency
fdt_static_dtb.S dependency in sys/conf/files is currently set as:
$S/boot/fdt/dts/${MACHINE}/${FDT_DTS_FILE}

This is wrong, as what fdt_static_dtb.S actually uses is the DTB file
produced from the FDT_DTS_FILE.
In addition it also makes using DTS files stored in $S/gnu/dts/${MACHINE}/
impossible.

So, change the dependency to "fdt_dtb_file", which seems to be the right
option here anyway.

It allows implementing loadable kernel modules with new actions and
without needing to modify kernel headers and ipfw(8). The module
registers its action handler and keyword string, that will be used
as action name. Using generic syntax user can add rules with this
action. Also ipfw(8) can be easily modified to extend basic syntax
for external actions, that become a part base system.

a6e0c5da99 New CAM I/O scheduler for FreeBSD. The default I/O scheduler is the same
as before. The common scheduling bits have moved from inline code in
each of the CAM periph drivers into a library that implements the
default scheduling.

In addition, a number of rate-limiting and I/O preference options can
be enabled by adding CAM_IOSCHED_NETFLIX to your config file. A number
of extra stats are also maintained. CAM_IOSCHED_NETFLIX isn't on by
default because it uses a separate BIO_READ and BIO_WRITE queue, so
doesn't honor BIO_ORDERED between these two types of operations. We
already didn't honor it for BIO_DELETE, and we don't depend on
BIO_ORDERED between reads and writes anywhere in the system (it is
currently used with BIO_FLUSH in ZFS to make sure some writes are
complete before others start and as a poor-man's soft dependency in
one place in UFS where we won't be issuing READs until after the
operation completes). However, out of an abundance of caution, it
isn't enabled by default.

Plus, this also brings in NCQ TRIM support for those SSDs that support
it. A black list is also provided for known rogues that use NCQ trim
as an excuse to corrupt the drive. It was difficult to separate out
into a separate commit.

This code has run in production at Netflix for over a year now.

VM_NUMA_ALLOC is used to enable use of domain-aware memory allocation in

reporting for devices such as bus_get_domain().

MAXMEMDOM must still be set to a value greater than for any NUMA support
to be effective.  Note that 'cpuset -gd' always works if MAXMEMDOM is
enabled and the system supports NUMA.

multiple identical copies of methods for various architectures.
