So that reinitialization, e.g. MTU change, will not fail when the system
memory is excessively fragmented.

The assumption that the channel is only opened upon synthetic device
attach time no longer holds, e.g. Hyper-V network device MTU changes.
We have to allow device drivers to preallocate bufrings, e.g. in
attach DEVMETHOD, to prevent bufring allocation failure once the
system memory is fragmented after running for a while.

SPI-mapped MSI interrupts coming from a controller other
than GICv2m need to have their trigger and polarity
properly configured. This patch fixes MSI/MSI-X
on Annapurna Alpine platform with GICv2.

PIC_SETUP_INTR implementation in GICv3 did not allow
for setting up interrupts without included FDT
description. GICv2m-like MSI interrupts, which map
MSI messages to SPI interrupt lines, may not have
a description in FDT. Add support for such interrupts
by setting the trigger and polarity to the appropriate
values for MSI (edge, high) and get the hardware
IRQ number from the corresponding ISRC.

There is nothing CPU specific here, and it's usable by both fdt and Open
Firmware based systems. Rather than keeping the same file in every one, just
add it to the ofw/fdt block in the main file.
Summary:
If the environment variable is set, U-boot adds a 'bootargs' property to
/chosen. This is already handled by ARM and MIPS, but should be handled in a
central location. For now, ofw_subr.c is a good place until we determine if it
should be moved to init_main.c, or somewhere more central to all architectures.
Eventually arm and mips should be modified to use ofw_parse_bootargs() as well,
rather than using the duplicate code already.

keep the beaglebone defaults: USB0 -> peripheral/gadget, USB1 -> host.
This is only a workaround as in fact fact this hardware is capable of detect
the USB port mode based on type of cable and act according with the detected
mode. Unfortunately the driver does not handle that at moment.

100.chksetuid and 110.neggrpperm try to search through all UFS and ZFS
filesystems. But their logic contains an error. They also search through
remote filesystems that are mounted on top of the root of a local
filesystem. For example, if a user installs a FreeBSD system with the
default ZFS layout, he'll get a zroot/usr/home filesystem. If he then mounts
/usr/home over NFS, these scripts would search through /usr/home.

This is in preparation for linking with LLVM's lld, which does not have

This will also allow all build targets to share a common linker binary.

bspatch previously included sys/capability.h or sys/capsicum.h based
on __FreeBSD_version, as FreeBSD is the upstream for bsdiff and we may
see this file incorporated into other third-party software.
The Capsicum header is now installed as sys/capsicum.h in stable/10 and
FreeBSD 10.3, so we can just use sys/capsicum.h and simplify the logic.
