e1ae911232 Partially revert r264083.
While it is the recommended initialization procedure, it hangs on the reset
of the second GPIO module on pandaboard.

Removes the module reset for now as more investigation would be needed.

e76013f8c8 An all-or-nothing approach to labels isn't flexible enough. Embedded
systems need fine-grained control over what's in and what's out.
That's ideal. For now, separate GPT labels from the rest and allow
g_label to be built with just GPT labels.

These should have been part of r264129, they are part of the overall set
of changes that got several weeks of testing.  I must have fumbled them
while merging various patchsets.

e8da9ba992 Make the vmm code compile with gcc too. Not entirely sure things are
correct for the pirbase test (since I'd have thought we'd need to do
something even when the offset is 0 and that test looks like a
misguided attempt to not use an uninitialized variable), but it is at
least the same as today.

78021d485d Do not prevent processes from making changes to the baudrate or the
CLOCAL and HUPCL control flags. There are legit reasons for allowing
those to be changed. When /etc/ttys has the "3wire" type (without a
baudrate) for the serial port that is the low-level console, then
this change has no effect.

60f16a83d9 In freebsd32_sendmsg(), replace the call to sockargs() followed by a
call to freebsd32_convert_msg_in() with freebsd32_copyin_control() to
readin and convert in a single step. This makes it simpler to put all
the control messages in a single mbuf or mbuf cluster as per the
limitations imposed upon us by ip6_setpktopts().

The logic is as follows:
1.  Go over the array of control messages to determine overall size
    and include extra padding for proper alignment as we go.
2.  Get a mbuf or mbuf cluster as needed or fail if the overall
    (adjusted) size is larger than a cluster.
3.  Go over the array of control messages again, but now copy them
    into kernel space and into aligned offsets.
4.  Update the length of the control message to take padding between
    the header and the data into account (but not for padding added
    between one control message and the next).

051ba34f7c - Fix the setup of interrupts for banks 2 and 3 on AM335x.
On AM335x each one of the four GPIO banks has two physical interrupt
    lines, so we now allocate resources and setup our interrupt handler for
    all the (8) available interrupts.

    On OMAP3 and OMAP4 there is only one interrupt for each GPIO bank (6
    banks, 6 interrupts), but there are two set of registers where the
    first one is used to setup the delivery of interrupts to the MPU and
    the second set, setup the delivery of interrupts to the DSP.

    On AM335x, each set of registers controls each one of the interrupt
    lines.

- Remove nonexistent registers for OMAP4 and AM335x, replace their use with
  the correct ones for these SoCs.

- Remove stray whitespace.

Based on OMAP3, OMAP4 and AM335x TRMs.

Tested on Beaglebone-black.

94f16d7a87 Add ioctl(2) calls to uftdi(4) to access bitbang, MPSSE, CPU_FIFO, and
other modes supported by the FTDI serial adapter chips.

In addition to adding the new ioctls, this change removes all the code
that reset the chip at attach and open/close time, and also the code
that turned on RTS/CTS flow control on open without any permission to do
so (that was just always a bug in the driver).

When FTDI chips are configured as GPIO or MPSSE or other special-purpose
uses by an attached serial eeprom, the chip will power on with certain
pins driven or floating, and it's important that the driver not do
anything to the chip to perturb that unless it receives a specific
command to do so.  When used for "plain old serial comms" the chip
powers on into the right mode and never needs to be reset while it's
running to operate properly, so this change is transparent to most users.

e965005b68 When KN_INFLUX is set on the knote due to kqueue_register() or
kqueue_scan() unlocking the kqueue to call f_event, knote() or
knote_fork() should not skip the knote.  The knote is not going to
disappear during the influx time, and the mutual exclusion between
scan and knote() is ensured by both code pathes taking knlist lock.
The race appears since knlist lock is before kq lock, so KN_INFLUX
must be set, kq lock must be dropped and only then knlist lock can be
taken.  The window between kq unlock and knlist lock causes lost
events.

Add a flag KN_SCAN to indicate that KN_INFLUX is set in a manner safe
for the knote(), and check for it to ignore KN_INFLUX in the knote*()
as needed.  Also, in knote(), remove the lockless check for the
KN_INFLUX flag, which could also result in the lost notification.

dd28e6bbc0 Add property and sysctl to control how ZVOLs are exposed to OS.
New ZFS property volmode and sysctl vfs.zfs.vol.mode allow switching ZVOL
between three modes:
 geom -- existing fully functional behavior (default);
 dev -- exposing volumes only as raw disk device file in devfs;
 none -- not exposing volumes outside ZFS.

The "dev" mode is less functional (can't be partitioned, mounted, etc),
but it is faster, and in some scenarios with untrusted consumers safer.
It can be useful for NAS, VM block storages, etc.
The "none" mode may be convenient for backup servers, etc. that don't
need direct data access.

Due to the way ZVOL is integrated with main ZFS code, those property
and sysctl are checked only during pool import and volume creation.

In my opinion we should have considered putting the userspace bits in a

that point.

bf6556bd2d Correct return type of pdfork(2).
The pdfork(2) man page states:

	"pdfork() returns a PID, 0 or -1, as fork(2) does."

As it returns a PID, the return type should obviously be pid_t. As int
and pid_t have the same size on all architectures, this change does not
affect the ABI in any way.
