Add support for SPI-mapped MSI interrupts outside of GICv2m.
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.

Add support for SPI-mapped MSI interrupts in GICv3.
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.
Add a ofw_parse_bootargs function, and use it for powerpc
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.

If present, honor the USB port mode (host or peripheral) set on DTS, if not,
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.

Fix periodic scripts when an NFS mount covers a local mount
100.chksetuid and 110.neggrpperm try to search through all UFS and ZFS

remote filesystems that are mounted on top of the root of a local

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.

[iwm] Improve reliability of iwm_release on disassociation a bit.
* We need to first call ivp->iv_newstate(), to enqueue the deauth/deassoc
mgmt frame, then flush the tx queue, before actually calling

* cycling a wlan connection via wpa_cli frontend to wpa_supplicant, by
issuing disconnect and reconnect commandos works quite well.
(There is still an issue when disconnecting/reconnecting too quickly)

Sync in latest vDSOs from upstream.
- Use conditional instruction to simplify the ARMv6 vDSO. This means
that we no longer perform any branching. In the failure case, we
simply slide over the assignments of the return values.
The vDSO could be improved even further by using stmia to do
assignments in parallel. Unfortunately, the script used to generate
these is not smart enough for that (yet).

If BIOS performed hand-off to OS with BSP LAPIC in the x2APIC mode,
system usually consumes such configuration without a notice, since
x2APIC is turned on by OS if possible (nop). But if BIOS
simultaneously requested OS to not use x2APIC, code assumption that
that xAPIC is active breaks.
In my opinion, we cannot safely turn off x2APIC if control is passed
in this mode. Make madt.c ignore user or BIOS requests to turn x2APIC
off, and do not check the x2APIC black list. Just trust the config
and try to continue, giving a warning in dmesg.

Be more strict when selecting between snapshot/regular mount.
Reclaimed vnode type is VBAD, so succesful comparision like
devvp->v_type != VREG does not imply that the devvp references
snapshot, it might be due to a reclaimed vnode. Explicitely check the
vnode type.
In the the most important case of ffs_blkfree(), the devfs vnode is
locked and its type is stable. In other cases, if the vnode is
reclaimed right after the check, hopefully the buffer methods return
right error codes.

Replace dirname(3) by a copy that complies to POSIX.
It turns out that the path normalization that our brand new copy of
dirname(3) does is actually not allowed by the draft version of the
upcoming version of POSIX. It has to behave identically to the
dirname(1) utility.
This change replaces our new dirname(3) implementation by yet another
version that doesn't implement the path normalization logic; it merely
looks for the end of the directory name and overwrites that with a null
byte.
