Move all Xeon secondary register setup to the setup_b2b_mw routine. We
use subroutines to make it a bit less wordy than the Linux version.
Adds a new tunable, 'hw.ntb.b2b_mw_share'. By default, it is off
(zero). If both sides enable it (any non-zero value), the NTB driver
attempts to use only half of a memory window for remote register MMIO
access.
This is still part of the large Linux rewrite (e26a5843).

This Linux commit was more or less a rewrite. Unfortunately, the commit
log does not give a lot of context for the rewrite. I have tried to
faithfully follow the changes made upstream, including matching function
names where possible, while churning the FreeBSD driver as little as
possible.
This is the bulk of the rewrite. There are two groups of changes to
follow in separate commits: fleshing out the rest of the changes to
xeon_setup_b2b_mw(), and some changes to if_ntb.
Yes, this is a big patch (3 files changed, 416 insertions(+), 237
deletions(-)), but the Linux patch was 13 files changed, 2,589
additions(+) and 2,195 deletions(-).
Original Linux commit log:
Change ntb_hw_intel to use the new NTB hardware abstraction layer.
Split ntb_transport into its own driver. Change it to use the new NTB
hardware abstraction layer.

interrupt controller.
The latter is required for INTRNG, because of the hardware erratum
workaround installed by the linux folks into the imx6 FDT data, which remaps
an ethernet interrupt to the gpio device. In the non-INTRNG world we
intercept the call to map the interrupt and map it back to the ethernet
hardware (because we don't need linux's workaround), but in the INTRNG world
we lose the hookpoint where that remapping was happening, but we gain the
ability to work the way linux does by having the gpio driver dispatch the
interrupt.

and armv6 architecures. The primary enhancement over the old design is
support for hierarchical interrupt controllers (such as a gpio driver
which can receive interrupts from a root PIC and act as a PIC itself for
clients interested in handling a change of gpio pin state as an
interrupt). The new code also provides an infrastructure for mapping
interrupts described in metadata in the form of a "controller reference
plus interrupt number" tuple into the simple "0-n" flat numeric space
understood by rman and the bus resource mechanisms.
Use of the new code is enabled by setting the ARM_INTRNG option, and by
making a few simple changes to the platform's support code. In addition
each existing PIC driver needs changes to be ready for INTRNG; this commit
contains the changes for the arm/gic driver, which most armv6 SoCs use, but
it does not enable the new code yet on any platform.
This project has been many years in the making, starting as a GSoC project
by Jakub Klama (jceel@) in 2012. That didn't get committed right away and
the source base evolved out from under it to some degree. In 2014 I rebased
the diffs to then -current and did some enhancements in the area of mapping
interrupt numbers and storing associated fdt data, then the project went
cold again for a while. Eventually Svata Kraus took that work in progress
and did another big round of work on it, removing most of the remaining
rough edges. Finally I took that and made one more pass through it, mostly
disabling the "INTR_SOLO" feature for now, pending further design
discussions on how to most efficiently dispatch a pending interrupt through
more than one layer of PIC. The current code with the INTR_SOLO feature
disabled uses approximate 100 extra cpu cycles for each cascaded PIC the
interrupt has to be passed to, so what's left to do is about efficiency, not
correct operation.

value is defined as a config option the definition is emitted into
opt_global.h which is force-included into everything. In addition, the
symbol is emitted by the genassym mechanism, but that by its nature reduces
the value to a 0xnnnnnnnn number. When compiling a .S file you end up
with two different definitions of the macro (they evaluate to the same
number, but the text is different, upsetting the compiler).
Nothing has changed about this code for a while but the compile error is
new, so this must be fallout from the clang 3.7 update or something.
The early ethernet MACs (I think AR71xx and AR913x) require that both
TX and RX require 4-byte alignment for all packets.
The later MACs have started relaxing the requirements.
For now, the 1-byte TX and 1-byte RX alignment requirements are only for
the QCA955x SoCs. I'll add in the relaxed requirements as I review the
datasheets and do testing.
* Add a hardware flags field and 1-byte / 4-byte TX/RX alignment.
* .. defaulting to 4-byte TX and 4-byte RX alignment.
* Only enforce the TX alignment fixup if the hardware requires a 4-byte
TX alignment. This avoids a call to m_defrag().
* Add counters for various situations for further debugging.
* Set the 1-byte and 4-byte busdma alignment requirement when
the tag is created.
This improves the straight bridging performance from 130mbit/sec
to 180mbit/sec, purely by removing the need for TX path bounce buffers.
The main performance issue is the RX alignment requirement and any RX
bounce buffering that's occuring. (In a local test, removing the RX
fixup path and just aligning buffers raises the performance to above
400mbit/sec.
In theory it's a no-op for SoCs before the QCA955x.
Tested:
* QCA9558 SoC in AP135 board, using software bridging between arge0/arge1.
an extra argument to specify the number of 1GiB pages to map. This should
be a nop as we are only mapping a single page, but when we move to use an
extra level of page tables we will be able to map a second block, e.g. if
the kernel was loaded over a 1GiB boundary.
This includes clang 3.5.0+, gcc 4.2.1, gcc 4.8.4+
This allows me to do subdirectory makes again after setting
MAKESYSPATH on 10.2-RELEASE as it comes with clang 3.4.1.
As a sidenote: this isn't technically correct for all vintages
of gcc 4.2.1, but will be correct when gcc is rebuilt/reinstalled
after r286074, so this version check should be good enough.

The 'includes' target is currently a pseudo target in bsd.subdir.mk that
does 'cd ${.CURDIR} && ${MAKE} buildincludes && ${MAKE} installincludes',
versus all over targets that just recurse.
In Makefile.inc1 the older duplicated bsd.subdir.mk logic for calling
'includes' was being executed in each subdir directly, meaning 'cd lib && make
includes' became 'cd lib && make buildincludes && make installincludes'. Now
that the bsd.subdir.mk logic is used it is calling 'make buildincludes && make
installincludes' from the top-level which pulls in the PATH=<default path>
from /Makefile.
The sub-make logic for 'includes' in bsd.subdir.mk was attempted to be removed
in r289282 but turned out to be wrong. I have a working version now but
it is not yet ready for commit. So for now in Makefile.inc1 split out
'includes' to 'buildincludes' and 'installincludes' which will avoid the
problem.

Bmake has a documented feature of '-N' to skip executing commands which is
specifically intended for debugging top-level builds and not recursing into
sub-directories. This matches the older 'make -n' behavior we added which made
'-n -n' the recursing target and '-n' a non-recursing target.
Removing the '-n -n' feature allows the build to work as documented in
the bmake manpage with '-n' and '-N'. The older '-n -n' feature was also
not documented anywhere that I could see.
Note that the ${_+_} var is still needed as currently bmake incorrectly
executes '+' commands when '-N' is specified.
The '-n' and '-n -n' features were broken for several reasons prior to this.
r251748 made '_+_' never expand with '-n -n' which resulted in many
sub-directories not being visited until fixed 2 years later in r288391, and
many targets were given .MAKE over the past few years which resulted in
non-sub-make commands, such as rm and ln and mtree, to be executed.
This should also allow removing some indirection hacks in bsd.subdir.mk and
other cases of .USE that have a .MAKE by using '+'.
