0108cce0a4 Adjust the order of operations in spinlock_enter() and spinlock_exit() to
work properly with single-stepping in a kernel debugger.  Specifically,
these routines have always disabled interrupts before increasing the nesting
count and restored the prior state of interrupts after decreasing the nesting
count to avoid problems with a nested interrupt not disabling interrupts
when acquiring a spin lock.  However, trap interrupts for single-stepping
can still occur even when interrupts are disabled.  Now the saved state of
interrupts is not saved in the thread until after interrupts have been
disabled and the nesting count has been increased.  Similarly, the saved
state from the thread cannot be read once the nesting count has been
decreased to zero.  To fix this, use temporary variables to store interrupt
state and shuffle it between the thread's MD area and the appropriate
registers.

761481dc63 - Remove an unused entry from the softc (only used in a debugging printf).
- Fix the loop count on detach (causing a panic on detaching a serial
  dongle).
- Increase a buffer in case some driver want extra long tty device names
  (postfixing the purpose of the tty for example, e.g. u3g.ppp).

0834ed4757 Bugfix: Move the 'at <location string' to the beginning of the attach
notification. devd would stop evaluating at 'at' (not '<k>=<v>') and
hence prevent 'port=X' (and 'bus=<"on" string>) from making it into the
environment for the devd action.

68fdfe2926 Partially implement the mysterious cons25 \e[x escape sequence.
It seems the terminfo library on some systems (OS X, Linux) may emit the
sequence \e[x to reset to default attributes. Apart from using the
zero-command, this escape sequence allows many more operations, such as
setting ANSI colors. I don't see this used anywhere, so this should be
sufficient for now.

This deficiency was spotted by the Debian GNU/kFreeBSD. They have their
own patch, which is slightly flawed in my opinion. I don't know why they
never reported this issue to us.

3b50d59fef x86 topo_probe: do not probe smp topology if only one cpu is visible
This could lead to a division by zero if hardware is multi-core and/or
multi-threaded, but for some (quite unusual) reason FreeBSD sees only
one logical processor.  This could happen, for example, if neither MADT
nor MP Table are presented by BIOS.

Also:
- assert in topo_probe_0x4 that BSP is accounted for
- neither cpu_cores nor cpu_logical should be zero after successful
  probing, so either being zero is an indication of failed probing

54c562081f Restructure the way the copyin/copyout segment is stored to prevent a
concurrency bug. Since all SLB/SR entries were invalidated during an
exception, a decrementer exception could cause the user segment to be
invalidated during a copyin()/copyout() without a thread switch that
would cause it to be restored from the PCB, potentially causing the
operation to continue on invalid memory. This is now handled by explicit
restoration of segment 12 from the PCB on 32-bit systems and a check in
the Data Segment Exception handler on 64-bit.

While here, cause copyin()/copyout() to check whether the requested
user segment is already installed, saving some pipeline flushes, and
fix the synchronization primitives around the mtsr and slbmte
instructions to prevent accessing stale segments.

1108273af4 Add initial BCM5718 family support. The BCM5718 family includes
the dual port BCM5717 and BCM5718 devices which are intended for
mainstream workstation and entry-level server designs and
represents the twelfth generation of NetXtreme Ethernet controllers.
This family is the successor to the BCM5714/BCM5715 family and
supports IPv4/IPv6 checksum offloading, TSO, VLAN hardware tagging,
jumbo frames, MSI/MSIX, IOV, RSS and TSS.

This change set supports all hardware features except IOV and
RSS/TSS. Unlike its predecessors, only extended RX buffer
descriptors can be posted to the jumbo producer ring. Single RX
buffer descriptors for jumbo frame are not supported. RSS requires
a more substantial set of changes and will apply to a larger set
of NetXtreme devices so RSS/TSS multi-queue support will be
implemented in a future releases.

c5dd9d8c37 Add a flag to the experimental NFSv4 client to indicate when
delegations are being returned for reasons other than a Recall.
Also, re-organize nfscl_recalldeleg() slightly, so that it leaves
clearing NMODIFIED to the ncl_flush() call and invalidates the
attribute cache after flushing. It is hoped that these changes
might fix the problem others have seen when using the NFSv4
client with delegations enabled, since I can't reliably reproduce
the problem. These changes only affect the client when doing NFSv4
mounts with delegations enabled.

ae19af49e0 Add two new loader tunables 'hw.acpi.install_interface' and
'hw.acpi.remove_interface'.  hw.acpi.install_interface lets you install new
interfaces.  Conversely, hw.acpi.remove_interface lets you remove OS
interfaces from the pre-defined list in ACPICA.  For example,

	hw.acpi.install_interface="FreeBSD"

lets _OSI("FreeBSD") method to return 0xffffffff (or success) and

	hw.acpi.remove_interface="Windows 2009"

lets _OSI("Windows 2009") method to return zero (or failure).  Both are
comma-separated lists and leading white spaces are ignored.  For example,
the following examples are valid:

	hw.acpi.install_interface="Linux, FreeBSD"
	hw.acpi.remove_interface="Windows 2006, Windows 2006.1"

7deff7f9b4 Bug fix delta to the em driver:
- Chasin down bogus watchdogs has led to an improved
	  design to this handling, the hang decision takes
	  place in the tx cleanup, with only a simple report
	  check in local_timer. Our tests have shown no false
	  watchdogs with this code.
	- VLAN fixes from jhb, the shadow vfta should be per
	  interface, but as global it was not. Thanks John.
	- Bug fixes in the support for new PCH2 hardware.
	- Thanks for all the help and feedback on the driver,
	  changes to lem with be coming shortly as well.

8e431dd6f1 Bring vfs.ufs.dirhash_maxmem into the age of the fruitbat and make it
autotuned. It is only an upper bound (the memory is not always allocated)
and the system contains a vm_lowmem handler so nothing will crash and burn
if it's tuned too high.

36c7255a81 - Given that in one-shot mode tick_et_start() also is called frequently
introduce function pointers once set up to the respective implementation
  for reading the (S)TICK and writing the (S)STICK_COMPARE registers as a
  compromise between duplicating code and selecting between different
  implementations during execution over and over again, similar to what is
  done elsewhere in the MD in order to support different CPU models that
  won't ever change at runtime.
- In the remaining tick interrupt handler further push down disabling of
  interrupts to the periodic case as it isn't necessary here in one-shot
  mode at all.

e7926a3703 Reimplemented "gpart destroy -F". Now it does all work in kernel.
This was needed for recover implementation.

Implement the recover command for GPT. Now GPT will marked as
corrupt when any of three types of corruption will be detected:
1. Damaged primary GPT header or table
2. Damaged secondary GPT header or table
3. Secondary header is not located in the last LBA
Marked GPT becomes read-only. Any changes with corrupt table
are prohibited. Only "destroy" and "recover" commands are allowed.

495ed64c16 The EHCI_CAPLENGTH and EHCI_HCIVERSION registers are actually sub-registers
within the first 4 bytes of the EHCI memory space. For controllers that
use big-endian MMIO, reading them with 1- and 2-byte reads would then
return the wrong values. Instead, read the combined register with a 4-byte
read and mask out the interesting quantities.
