b4122742a6 Be more robust with malformed interrupt config data. Instead of crashing
or going into a near-infinite loop, warn and make potentially-reasonable
assumptions.

e4be5a1636 Add a set of helpers (ofw_bus_get_status() and ofw_bus_status_okay()) to
process "status" properties of OF nodes.

I've avoided adding new KOBJ methods here so that we don't have to modify
every ofw_bus in the tree. Since 100% of implementations of ofw_bus use
only ofw_bus_gen_*(), it might be worth garbage-collecting the other
methods as well.

54fb8142b6 Use m_defrag() instead of m_collapse() to compact a long mbuf chain
This should be an infrequent occurrence, so remove the per-queue
counters in favor of just global counters in the softc.

443c3d0bd1 Do not place the sglist used for Rx/Tx on the stack
The sglist segment array has grown to a bit over 512 bytes (on
64-bit system) which is more than ideally should be put on the
stack. Instead allocate an appropriately sized sglist and hang
it off each Rx/Tx queue structure.

Bump the maximum number of Tx segments to 64 to make it unlikely
we'll have defragment an mbuf chain. Our previous count was
rounded up to this value since it is the next power of two, so
effective memory usage should not change.

Also only allocate the maximum number of Tx segments if TSO was
negotiated.

06763f5e55 Provide a simpler and more standards-compliant simplebus implementation to
get the Routerboard 800 up and running with the vendor device tree. This
does not implement some BERI-specific features (which hopefully won't be
necessary soon), so move the old code to mips/beri, with a higher attach
priority when built, until MIPS interrupt domain support is rearranged.

bbc6da03ef Open Firmware interrupt specifiers can consist of arbitrary-length byte
strings and include arbitrary information (IRQ line/domain/sense). When the
ofw_bus_map_intr() API was introduced, it assumed that, as on most systems,
these were either 1 cell, containing an interrupt line, or 2, containing
a line number plus a sense code. It turns out a non-negligible number of
ARM systems use 3 (or even 4!) cells for interrupts, so make this more
general.

169dd953b0 Add hwpmc(4) support for the PowerPC 970 class processors, direct events.
This also fixes asserts on removal of the module for the mpc74xx.

The PowerPC 970 processors have two different types of events: direct events
and indirect events.  Thus far only direct events are supported.  I included
some documentation in the driver on how indirect events work, but support is
for the future.

r261266:
  Add a jail parameter, allow.kmem, which lets jailed processes access
  /dev/kmem and related devices (i.e. grants PRIV_IO and PRIV_KMEM_WRITE).
  This in conjunction with changing the drm driver's permission check from
  PRIV_DRIVER to PRIV_KMEM_WRITE will allow a jailed Xorg server.

7e3343bfcf Some BIOSes incorrectly use standard memory resource ranges to list
the memory ranges that they decode for downstream devices rather than
creating ResourceProducer range resource entries.  The result is that
we allocate the full range to the PCI root bridge device causing
allocations in child devices to all fail.

As a workaround, ignore any standard memory resources on a PCI root
bridge device.  It is normal for a PCI root bridge to allocate an I/O
resource for the I/O ports used for PCI config access, but I have not
seen any PCI root bridges that legitimately allocate a memory resource.

1c006b57f6 When detaching a [USB] keyboard, keys might still be pressed. Ensure
that all pressed keys are released before completing the USB keyboard
detach. This will prevent so-called "ghost-keys" from appearing after
that the USB device generating the key event(s) has been detached.

a timeout value of a single tick is given. With FreeBSD-10 and newer
the current system time is used as a starting point, and the minimum
callout time of a single tick will be guaranteed. This patch mostly
affect the DMA delay timeouts, which are typically in the range from
0.125 to 2ms.
