rather than u_char.

To try and play nice with the ABI, the u_char CPU ID values are clamped
at 254.  The new fields now contain the full CPU ID, or -1 for no cpu.

7c26b0a7c8 Add a workaround needed to fix a bug of Arasan Host Controller where it may
lose the contents of consecutive writes (that happens within two SD card
clock cycles).

This fixes the causes of instability during the SD card detection and
identification on Raspberry Pi (which happens at 400 kHz and so was much
more vulnerable to this issue).

Remove the previous workaround which clearly can't provide the same effect.

2ffc65f982 Add a driver for the TI watchdog.
The TI watchdog timer is present on BeagleBone's.  Since 2014, U-Boot
has been booting the BeagleBone with the watchdog enabled.  We need to
disable it on boot to avoid a spurious reset.
The timer isn't exactly precise, but it will do as a watchdog.  This
is also a reflection of the watchdog(9) API.

In the future, we could handle interrupts, but the watchdog(9) API
needs to be a bit smarter before that can happen.

a5928b20d5 fwsectors and fwheads used to be somehwat arbitrary. However, they are
used to align partitions in gpart. We also try to align partitions by
stripe size when creating new media. Align these two concepts by
making fwsectors the same as the stripe size. Select a sensible number
of heads so we wind up with about 20 cylinders. This number was
selected to keep the rounding effects to a few percent while keeping
the number of cylinder groups low.

Sadly, it is not possible to make these numbers match the numbers used
by SD card readers. There apperas to be much variation between brands
so there's no one universal number. These numbers are also not aligned
to the stripe size, so some performance problems may still be present
when SD cards are created this way.

Also, these numbers will differ from the far less common SD to ATA
adapters, which present a different, but more uniform, set of numbers
that also happened to match the old defaults.

Nothing should change for current users. Any suboptimal performance
caused by misalignment will still be there. gpart will honor the
partitions that aren't on proper boudnaries, but editing the partition
tables may result in different alignments being used than before when
editing things natively.

Ideally, there'd be some way to override these values in the disk
subsystem by the user for the USB adapter use case where all "native"
notions of geometry disappear. This does not implement that.

ca6505b818 Prevent ZFS leaking pool free space
When processing async destroys ZFS would leak space every txg timeout
(5 seconds by default), if no writes occurred, until the pool is totally
full. At this point it would be unfixable without a pool recreation.

In addition if the machine was rebooted with the pool in this situation
would fail to import on boot, hanging indefinitely, as the import process
requires the ability to write data to the pool. Any attempts to query the
pool status during the hung import would not return as the import holds
the pool lock.

The only way to import such a pool would be to specify -o readonly=on
to the zpool import.

zdb -bb <pool> can be used to check for "deferred free" size which is where
this lost space will be counted.

f0cace5d94 When deciding whether to call m_pullup() even though there is adequate
data in an mbuf, use M_WRITABLE() instead of a direct test of M_EXT;
the latter both unnecessarily exposes mbuf-allocator internals in the
protocol stack and is also insufficient to catch all cases of
non-writability.

(NB: m_pullup() does not actually guarantee that a writable mbuf is
returned, so further refinement of all of these code paths continues to
be required.)

a13a821641 Merge projects/ipfw to HEAD.
Main user-visible changes are related to tables:

* Tables are now identified by names, not numbers.
 There can be up to 65k tables with up to 63-byte long names.
* Tables are now set-aware (default off), so you can switch/move
 them atomically with rules.
* More functionality is supported (swap, lock, limits, user-level lookup,
 batched add/del) by generic table code.
* New table types are added (flow) so you can match multiple packet fields at once.
* Ability to add different type of lookup algorithms for particular
 table type has been added.
* New table algorithms are added (cidr:hash, iface:array, number:array and
 flow:hash) to make certain types of lookup more effective.
* Table value are now capable of holding multiple data fields for
  different tablearg users

Performance changes:
* Main ipfw lock was converted to rmlock
* Rule counters were separated from rule itself and made per-cpu.
* Radix table entries fits into 128 bytes
* struct ip_fw is now more compact so more rules will fit into 64 bytes
* interface tables uses array of existing ifindexes for faster match

ABI changes:
All functionality supported by old ipfw(8) remains functional.
 Old & new binaries can work together with the following restrictions:
* Tables named other than ^\d+$ are shown as table(65535) in
 ruleset in old binaries

Internal changes:.
Changing table ids to numbers resulted in format modification for
 most sockopt codes. Old sopt format was compact, but very hard to
 extend (no versioning, inability to add more opcodes), so
* All relevant opcodes were converted to TLV-based versioned IP_FW3-based codes.
* The remaining opcodes were also converted to be able to eliminate
 all older opcodes at once
* All IP_FW3 handlers uses special API instead of calling sooptcopy*
 directly to ease adding another communication methods
* struct ip_fw is now different for kernel and userland
* tablearg value has been changed to 0 to ease future extensions
* table "values" are now indexes in special value array which
 holds extended data for given index
* Batched add/delete has been added to tables code
* Most changes has been done to permit batched rule addition.
* interface tracking API has been added (started on demand)
 to permit effective interface tables operations
* O(1) skipto cache, currently turned off by default at
 compile-time (eats 512K).

* Several steps has been made towards making libipfw:
  * most of new functions were separated into "parse/prepare/show
    and actuall-do-stuff" pieces (already merged).
  * there are separate functions for parsing text string into "struct ip_fw"
    and printing "struct ip_fw" to supplied buffer (already merged).
* Probably some more less significant/forgotten features

80b47aefa1 Move the SCTP syscalls to netinet with the rest of the SCTP code. The
syscalls themselves are tightly coupled with the network stack and
therefore should not be in the generic socket code.

The following four syscalls have been marked as NOSTD so they can be
dynamically registered in sctp_syscalls_init() function:
  sys_sctp_peeloff
  sys_sctp_generic_sendmsg
  sys_sctp_generic_sendmsg_iov
  sys_sctp_generic_recvmsg

The syscalls are also set up to be dynamically registered when COMPAT32
option is configured.

As a side effect of moving the SCTP syscalls, getsock_cap needs to be
made available outside of the uipc_syscalls.c source file.  A proper
prototype has been added to the sys/socketvar.h header file.

API tests from the SCTP reference implementation have been run to ensure
compatibility. (http://code.google.com/p/sctp-refimpl/source/checkout)

c19f98eb74 Check for mbuf copy failure when there are multiple multicast sockets
This partitular case is the only path where the mbuf could be NULL.
udp_append() checked for a NULL mbuf only after invoking the tunneling
callback. Our only in tree tunneling callback - SCTP - assumed a non
NULL mbuf, and it is a bit odd to make the callbacks responsible for
checking this condition.

This also reduces the differences between the IPv4 and IPv6 code.

383f423be1 Fix draining in ttydev_leave():
1.  ERESTART is not only returned when the revoke count changed. It
    is also returned when a signal is received. While a change in
    the revoke count should be ignored, a signal should not.
2.  Waiting until the output queue is entirely drained can cause a
    hang when the underlying device is stuck or broken.

Have tty_drain() take care of this by telling it when we're leaving.
When leaving, tty_drain() will use a timed wait to address point 2
above and it will check the revoke count to handle point 1 above.
The timeout is set to 1 second, which is arbitrary and long enough
to expect a change in the output queue.

839ee02531 In the passthru IOCTL path, the mfi command pool was freely accessible N times
where as there are limited number(32) of mfi commands in the pool.
The mfi command pool is now restricted to 27 simultaneous accesses by using
a counting semaphore while calling the passthru function.

In the mrsas_cam.c source file there was a same function name mrsas_poll(),
which was same as the mrsas_poll() implemented in the mrsas.c file for the
polling interface.
To clearly distinguish the functionality by usage we have renamed the former
as mrsas_cam_poll().

In the passthru function let's say it has got an mfi command from the pool
but it has failed in one of the DMA function call which will lead to leak
an mfi command because in the ERROR case it directly returns and not freeing up
the occupied mfi command.

4799d48568 Current MegaRAID firmware and hence the driver only supported 64VDs.
E.g: If the user wants to create more than 64VD on a controller,
    it is not possible on current firmware/driver.

New feature and requirement to support upto 256VD, firmware/driver/apps need changes.
In addition to that, there must be a backward compatibility of the new driver with the
older firmware and vice versa.

RAID map is the interface between Driver and FW to fetch all required
fields(attributes) for each Virtual Drives.
In the earlier design driver was using the FW copy of RAID map where as
in the new design the Driver will keep the RAID map copy of its own; on which
it will operate for any raid map access in fast path.

Local driver raid map copy will provide ease of access through out the code
and provide generic interface for future FW raid map changes.

For the backward compatibility driver will notify FW that it supports 256VD
to the FW in driver capability field.
Based on the controller properly returned by the FW, the Driver will know
whether it supports 256VD or not and will copy the RAID map accordingly.

At any given time, driver will always have old or new Raid map.
