Reset the timer interrupt status register at the top rather than bottom of
the interrupt handler. If the event callback starts a new short timeout,
the timer can fire before returning from the event callback, and clearing
the interrupt status after that loses the interrupt and hangs until the
counter wraps. Fixing all of this removes the need for the do-nothing
loop at the top of the handler which really just waited for the counter to
roll over and reach the one-shot count again.
Also add a missing return(0) in the periodic timer start case.
Expand the list of compatible devices this driver works with. Increase
the target frequency from 1 to 10 MHz because these SoCs are plenty fast
enough to benefit from the extra event timer resolution.
Rework the imx ehci driver so that it's four separate ehci units rather
than one unit with four busses attached to it. This allows us to use
existing fdt data which describes separate devices with separate resources.
It also allows any combination of the units to be en/disabled in the
board dts files.
Adjust our dts code to match what's used by linux and u-boot now that
we're structured to do so.
The change that triggered the need for this on head was r257244. That
hasn't been MFC'd yet, but there's no harm in paving the way for it with
this MFC.
Remove all #include <machine/pmap.h> from arm code. It's already
included by vm/pmap.h, which is a prerequisite for arm/machine/pmap.h
so there's no reason to ever include it directly.
Remove #include <machine/frame.h> from all the arm code that doesn't
really need it. That would be almost everywhere it was included. Add
it in a couple files that really do need it and were previously getting
it by accident via another header.
Remove the last dregs of trapframe_t. It turns out only arm was using
this type, so remove it to make arm code more consistant with other
platforms.
Make geom_label(4) resize-aware. This fixes a situation when "gpart resize"
would resize a partition, but label providers - e.g. /dev/gptid/XXX - would
stay the same size.
MFC r256766:
Fix build with gcc by spelling unused format string as "unused" instead of NULL.

Removes strict-aliasing warnings from newer GCC in tcpdump.
Corresponds to MFC r258573, but for some reason our new pre-commit hooks
will not let us merge it from there.
Convert the if/else list of compatible devices to the table-driven
ofw_bus_search_compatible() routine. In addition to converting existing
strings to table entries, also add compat strings for the whole imx family.
Maximize available kva space by doing static device mapping from the top
of the address space downwards, and then returning the lowest mapped
device address from initarm_lastaddr(). Premap most of the device's
on-chip peripherals.
gperf: bring a small update from Apple Developers tools 4.4

offset.patch
Makes use the C offsetof() macro.
We are not merging the size_type.patch as it raises some
(apparently) bogus warnings and is not really used.

Add a driver for the Freescale Fast Ethernet Controller found on various
Freescale SoCs including the i.MX series. This also works for the newer
SoCs with the ENET gigabit controller, but doesn't use any of the new
hardware features other than enabling gigabit speed.
Mask out non-address bits in the mac address register, for proper
detection of an all-zeroes address. Also remove a misplaced return.
Switch to using ofw_bus_search_compatible() table-driven compat lookup.
Add compat strings for Freescale Vybrid family SoCs.
Add a helper routine to search for a compat string in a table that
associates compat strings with arbitrary values that mean something to
the driver. This is handy for drivers that support several variations
of similar hardware and need to know which one matched.

Add cases for the combinations of busdma sync op flags that we handle
correctly by doing nothing, then add a panic for the default case, because
that implies that some driver asked for a sync (probably incorrectly) and
nothing was done.
When calculating the number of bounce pages needed, round the maxsize
up to a multiple of PAGE_SIZE, and add one page because there can always
be one more boundary crossing than the number of pages in the transfer.
Fix a register name typo. The effect was that CPU_CONTROL_AFLT_ENABLE
wasn't being set, but it was almost assuredly already turned on anyway
by the bootloader.
Properly refuse handoff requests on already connected sessions. Previously
this would result in dropping the session.

r258694:
Make RTAS calls, which call setfault() to recover from machine checks,
preserve any existing fault buffer. RTAS calls are meant to be safe from
interrupt context (and are indeed used there to implement the xics PIC
driver). Without this, calling into RTAS in interrupt context would have
the effect of clearing any existing onfault state of the interrupted
thread, potentially leading to a panic.
r258427:
For PCI<->PCI bridges, #address-cells may be 3. Allow this when parsing the
ibm,dma-window properties. This is especially a concern when
#ibm,dma-address-cells is not specified and we have to use the regular
#address-cells property.
r258052:
Following the approach with ACPI DMAR on x86, split IOMMU handling into
a variant PCI bus instead of trying to shoehorn it into the PCI host bridge
adapter. Besides matching better the architecture on other platforms, this
also allows systems with multiple partitionable endpoints per PCI host
bridge to work correctly.
r258051:
Actually add IOMMU domain to the list of known mappings. This fixes a bug
where multiple devices in the same IOMMU domain would be allocated
conflicting mappings unless they also shared a DMA tag.
