2e92ac56dd Back out r197581, which replaced this file witk sys/kern/vfs_export.c.
Who knew that "svn export" was an actual command, or that I would have
vfs_export.c stuck in my mind deep enough to type "export" instead of
"commit"?

1eaff126fa Temporarily disable the use of 1GB page mappings by the direct map. There
are currently two problems with the use of 1GB page mappings by the direct
map.  First, at least one device driver uses pmap_extract() rather than
DMAP_TO_PHYS() to translate a direct map address to a physical address.
Unfortunately, neither pmap_extract() nor pmap_kextract() yet support 1GB
page mappings.  Second, pmap_bootstrap() needs to interrogate the MTRRs to
ensure that a 1GB page mapping doesn't span two MTRRs of different types.

82aebf697c Add two new fcntls to enable/disable read-ahead:
- F_READAHEAD: specify the amount for sequential access.  The amount is
   specified in bytes and is rounded up to nearest block size.
 - F_RDAHEAD: Darwin compatible version that use 128KB as the sequential
   access size.

A third argument of zero disables the read-ahead behavior.

Please note that the read-ahead amount is also constrainted by sysctl
variable, vfs.read_max, which may need to be raised in order to better
utilize this feature.

Thanks Igor Sysoev for proposing the feature and submitting the original
version, and kib@ for his valuable comments.

13dcbd75c1 Use correct sizeof() object for klist 'list'. Currently, struct klist
contained only SLIST_HEAD as its member, thus sizeof(struct klist) would
equal to sizeof(struct klist *), so this change makes the code more
correct in terms of semantics, but should be a no-op to compiler at this
time.

- clean up USB detach logic. There seems to be some problems detaching multiple
  USB HUBs connected in series from the root.

- after this patch the rule is:
  1) Always use device_detach() on the USB HUB first.
  2) Never just device_delete_child() on the USB HUB, because that function
  will traverse to all the device leaves and free them first, and then the USB
  stack will free the devices twice which doesn't work very well.

- make sure the did DMA delay gets set after the timeout has elapsed to make
  logic more clear. There is no functional difference.

53e69c0c2a Add support for VT200-style mouse input.
Right now if applications want to use the mouse on the command line,
they use sysmouse(4) and install a signal handler in the kernel to
deliver signals when mouse events arrive. This conflicts with my plan to
change to TERM=xterm, so implement proper VT200-style mouse input.

Because mouse input is now streamed through the TTY, it means you can
now SSH to another system on the console and use the mouse there as
well. The disadvantage of the VT200 mouse protocol, is that it doesn't
seem to generate events when moving the cursor. Only when pressing and
releasing mouse buttons.

There are different protocols as well, but this one seems to be most
commonly supported.

27bfa95847 Do not allow mmap with the MAP_FIXED argument to map at address zero.
This is done to make it harder to exploit kernel NULL pointer security
vulnerabilities.  While this of course does not fix vulnerabilities,
it does mitigate their impact.

Note that this may break some applications, most likely emulators or
similar, which for one reason or another require mapping memory at
zero.

This restriction can be disabled with the security.bsd.mmap_zero

56a4365bde Add 256 color support.
It is quite inconvenient that if an application for xterm uses 256 color
mode, text suddenly starts to blink (because of ;5; in the middle).
We'd better just implement 256 color mode and add a conversion routine
from 256 to 8 color mode, which doesn't seem to be too bad in practice.

Remapping colors is done quite simple. If one of the channels is most
actively represented, primary colors are used. If two channels are most
actively represented, secondary colors are used. If all three channels
are equal (gray), it picks between black and white.

4507f02e0e lindev(4) [1] is supposed to be a collection of linux-specific pseudo
devices that we also support, just not by default (thus only LINT or
module builds by default).

While currently there is only "/dev/full" [2], we are planning to see more
in the future.  We may decide to change the module/dependency logic in the
future should the list grow too long.

This is not part of linux.ko as also non-linux binaries like kFreeBSD
userland or ports can make use of this as well.

fbcd1b6eac Make SCS work in 8-bit mode.
This means we can finally do things like VT100 box drawing when using
Syscons (8-bit characters). As far as I know, the only remaining issue
is the absense of proper escape sequences for special keyboard
characters (cursor, F1 to F12, etc) and xterm emulation should be ready
for general use.

Enabling xterm would have the following advantages:

- Easier possible migration to Unicode. cons25 termcap entries are very
  8-bit centric. They use things like CP437 characters for box drawing,
  etc.

- Better support for SSH'ing to other operating systems/devices. Most
  switches use VT100-style admin interfaces.

- Reduced bandwidth, because applications can now use things like
  scrolling regions.

- You can finally use applications like dtach(1) on both the console and
  inside an xterm.

Also align setup descriptor on 32 bytes boundary. Tx buffer have no

ad8294cf98 Before calling vflush(FORCECLOSE) mark file system as unmounted so the
following vnops will fail. This is very important, because without this change
vnode could be reclaimed at any point, even if we increased usecount. The only
way to ensure that vnode won't be reclaimed was to lock it, which would be very
hard to do in ZFS without changing a lot of code. With this change simply
increasing usecount is enough to be sure vnode won't be reclaimed from under
us. To be precise it can still be reclaimed but we won't be able to see it,
because every try to enter ZFS through VFS will result in EIO.

zfs_root(). Introduce ZFS_ENTER_NOERROR() macro that only locks

the work area was totally unsynchronized which means this driver only
  had a chance of working on x86 when no bounce buffers were involved,
  which isn't that likely given that support for 64-bit DMA is currently
  broken throughout ata(4).
- Add necessary little-endian conversion of accesses to the work area,
  making this driver work on big-endian hosts. While at it, use the
  alignment-agnostic byte order encoders in order to be on the safe side.

eb811915d2 - According to Linux, the ALi M5451 can do 31-bit DMA instead of just
30-bit like the reset of the controllers supported by this driver.
  Actually ALi M5451 can be setup up to generate 32-bit addresses by
  setting the 31st bit via the accompanying ISA bridge, which allows
  it to work in sparc64 machines whose IOMMU require at least 32-bit
  DMA. Even though other architectures would also benefit from 32-bit
  DMA, enabling this bit is limited to sparc64 as bus_dma(9) doesn't
  generally guarantee that a low address of BUS_SPACE_MAXADDR_32BIT
  results in a buffer in the 32-bit range.
- According to Tatsuo YOKOGAWA's ali(4), the the DMA transfer size of
  ALi M5451 is fixed to 64k and in fact using the default size of 4k
- The 4DWAVE DX and NX require the recording buffer to be 8-byte
  aligned so adjust the bus_dma_tag_create(9) accordingly.
- Unlike the rest of the controllers supported by this driver, the
  ALi M5451 only has 32 hardware channels instead of 64 so limit the
  loop in tr_intr() accordingly. [1]

- Ensure the transmit routines aren't attempting to PIO write to doorbells

- Download the correct f/w, rather than using the EEPROM f/w after reset.
- Export a count of the number of watchdog resets via sysctl

46ce5e26a7 Extend the keyboard character size to 24 bits.
Because we use an int to store keyboard chacacters and their flags, we
can easily store the flags in the top byte instead of the second byte.
This means it's a lot easier to make Unicode work.

The only change that still needs to be made, is that keyent_t's map is
extended to u_int.

435068aab7 Fix sched_switch_migrate():
- In 8.x and above the run-queue locks are nomore shared even in the
  HTT case, so remove the special case.
- The deadlock explained in the removed comment here is still possible
  even with different locks, with the contribution of tdq_lock_pair().
  An explanation is here:
  (hypotesis: a thread needs to migrate on another CPU, thread1 is doing
  sched_switch_migrate() and thread2 is the one handling the sched_switch()
  request or in other words, thread1 is the thread that needs to migrate
  and thread2 is a thread that is going to be preempted, most likely an
  idle thread. Also, 'old' is referred to the context (in terms of
  run-queue and CPU) thread1 is leaving and 'new' is referred to the
  context thread1 is going into.  Finally, thread3 is doing tdq_idletd()
  or sched_balance() and definitively doing tdq_lock_pair())

  * thread1 blocks its td_lock. Now td_lock is 'blocked'
  * thread1 drops its old runqueue lock
  * thread1 acquires the new runqueue lock
  * thread1 adds itself to the new runqueue and sends an IPI_PREEMPT
    through tdq_notify() to the new CPU
  * thread1 drops the new lock
  * thread3, scanning the runqueues, locks the old lock
  * thread2 received the IPI_PREEMPT and does thread_lock() with td_lock
    pointing to the new runqueue
  * thread3 wants to acquire the new runqueue lock, but it can't because
    it is held by thread2 so it spins
  * thread1 wants to acquire old lock, but as long as it is held by
    thread3 it can't
  * thread2 going further, at some point wants to switchin in thread1,
    but it will wait forever because thread1->td_lock is in blocked state

This deadlock has been manifested mostly on 7.x and reported several time
on mailing lists under the voice 'spinlock held too long'.
Many thanks to des@ for having worked hard on producing suitable textdumps

7746b6461d Work-around READDIRPLUS problem with .zfs/ and .zfs/snapshot/ directories
by just returning EOPNOTSUPP. This will allow NFS server to fall back to
regular READDIR.

Note that converting inode number to snapshot's vnode is expensive operation.
Snapshots are stored in AVL tree, but based on their names, not inode numbers,
so to convert inode to snapshot vnode we have to interate over all snalshots.

This is not a problem in OpenSolaris, because in their READDIRPLUS
implementation they use VOP_LOOKUP() on d_name, instead of VFS_VGET() on
d_fileno as we do.

a283298ce3 Improve flexibility of receiving Router Advertisement and
automatic link-local address configuration:

- Convert a sysctl net.inet6.ip6.accept_rtadv to one for the
  default value of a per-IF flag ND6_IFF_ACCEPT_RTADV, not a
  global knob.  The default value of the sysctl is 0.

- Add a new per-IF flag ND6_IFF_AUTO_LINKLOCAL and convert a
  sysctl net.inet6.ip6.auto_linklocal to one for its default
  value.  The default value of the sysctl is 1.

- Make ND6_IFF_IFDISABLED more robust.  It can be used to disable
  IPv6 functionality of an interface now.

- Receiving RA is allowed if ip6_forwarding==0 *and*
  ND6_IFF_ACCEPT_RTADV is set on that interface.  The former
  condition will be revisited later to support a "host + router" box
  like IPv6 CPE router.  The current behavior is compatible with
  the older releases of FreeBSD.

- The ifconfig(8) now supports these ND6 flags as well as "nud",
  "prefer_source", and "disabled" in ndp(8).  The ndp(8) now
  supports "auto_linklocal".

We don't need to check for group filter UNDEFINED state at t1,
because we only ever allocate filters with their groups, so we
unconditionally reject such calls with EINVAL.
Trying to change the active filter mode w/o going through IP_MSFILTER
is also disallowed.
