MFC r249625:
Introduce kern.timecounter.smp_tsc_adjust tunable (disabled by default) and
respective functionality, allowing to synchronize TSC on APs to match BSP's
during boot.  It may be unsafe in general case due to theoretical chance of
later drift if CPUs are using different clock rate or source, but it allows
to use TSC in some cases when difference caused by some initialization bug,
while TSCs are known to increment synchronously.

Be (very) careful about how to add more TX DMA work.

The list-based DMA engine has the following behaviour:

* When the DMA engine is in the init state, you can write the first
  descriptor address to the QCU TxDP register and it will work.

* Then when it hits the end of the list (ie, it either hits a NULL
  link pointer, OR it hits a descriptor with VEOL set) the QCU
  stops, and the TxDP points to the last descriptor that was transmitted.

* Then when you want to transmit a new frame, you can then either:
  + write the head of the new list into TxDP, or
  + you write the head of the new list into the link pointer of the
    last completed descriptor (ie, where TxDP points), then kick
    TxE to restart transmission on that QCU>

* The hardware then will re-read the descriptor to pick up the link
  pointer and then jump to that.

Now, the quirks:

* If you write a TxDP when there's been no previous TxDP (ie, it's 0),
  it works.

* If you write a TxDP in any other instance, the TxDP write may actually
  fail.  Thus, when you start transmission, it will re-read the last
  transmitted descriptor to get the link pointer, NOT just start a new
  transmission.

So the correct thing to do here is:

* ALWAYS use the holding descriptor (ie, the last transmitted descriptor
  that we've kept safe) and use the link pointer in _THAT_ to transmit
  the next frame.

* NEVER write to the TxDP after you've done the initial write.

* .. also, don't do this whilst you're also resetting the NIC.

With this in mind, the following patch does basically the above.

* Since this encapsulates Sam's issues with the QCU behaviour w/ TDMA,
  kill the TDMA special case and replace it with the above.

* Add a new TXQ flag - PUTRUNNING - which indicates that we've started
  DMA.

* Clear that flag when DMA has been shutdown.

* Ensure that we're not restarting DMA with PUTRUNNING enabled.

* Fix the link pointer logic during TXQ drain - we should always ensure
  the link pointer does point to something if there's a list of frames.
  Having it be NULL as an indication that DMA has finished or during
  a reset causes trouble.

Now, given all of this, i want to nuke axq_link from orbit.  There's now HAL
methods to get and set the link pointer of a descriptor, so what we
should do instead is to update the right link pointer.

* If there's a holding descriptor and an empty TXQ list, set the
  link pointer of said holding descriptor to the new frame.

* If there's a non-empty TXQ list, set the link pointer of the
  last descriptor in the list to the new frame.

* Nuke axq_link from orbit.

Note:

* The AR9380 doesn't need this.  FIFO TX writes are atomic.  As long as
  we don't append to a list of frames that we've already passed to the
  hardware, all of the above doesn't apply.  The holding descriptor stuff
  is still needed to ensure the hardware can re-read a completed
  descriptor to move onto the next one, but we restart DMA by pushing in
  a new FIFO entry into the TX QCU.  That doesn't require any real
  gymnastics.

Tested:

* AR5210, AR5211, AR5212, AR5416, AR9380 - STA mode.

grep: change some int types.

Change several int variables to size_t, ssize_t, or ptrdiff_t.
This should fix the bug described in CVE-2012-5667 when an input
line is so long that its length cannot be stored in an int
variable.

This is based on NetBSD's revision which says:

This change to NetBSD's version of GNU grep 2.5.1 (licenced under
GPLv2) was made without direct reference to any code licenced
under GPLv3.

popen(): Add 'e' mode character to set close-on-exec on the new fd.

If 'e' is used, the kernel must support the recently added pipe2() system
call.

The use of pipe2() with O_CLOEXEC also fixes race conditions between
concurrent popen() calls from different threads, even if the close-on-exec
flag on the fd of the returned FILE is later cleared (because popen() closes
all file descriptors from earlier popen() calls in the child process).
Therefore, this approach should be used in all cases when pipe2() can be
assumed present.

The old version of popen() rejects "re" and "we" but treats "r+e" like "r+".

Add basic support for FDT to i386 & amd64. This change includes:
1.  Common headers for fdt.h and ofw_machdep.h under x86/include
    with indirections under i386/include and amd64/include.
2.  New modinfo for loader provided FDT blob.
3.  Common x86_init_fdt() called from hammer_time() on amd64 and
    init386() on i386.
4.  Split-off FDT specific low-level console functions from FDT
    bus methods for the uart(4) driver. The low-level console
    logic has been moved to uart_cpu_fdt.c and is used for arm,
    mips & powerpc only. The FDT bus methods are shared across
    all architectures.
5.  Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the
    fdt_pic_table[] arrays. Both are empty right now.

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.

Enable the use of TDMA on an 802.11n channel (with aggregation disabled,
of course.)

There's a few things that needed to happen:

* In case someone decides to set the beacon transmission rate to be
  at an MCS rate, use the MCS-aware version of the duration calculation
  to figure out how long the received beacon frame was.

* If TxOP enforcing is available on the hardware and we're doing TDMA,
  enable it after a reset and set the TDMA guard interval to zero.
  This seems to behave fine.

TODO:

* Although I haven't yet seen packet loss, the PHY errors that would be
  triggered (specifically Transmit-Override-Receive) aren't enabled
  by the 11n HAL.  I'll have to do some work to enable these PHY errors
  for debugging.

What broke:

* My recent changes to the TX queue handling has resulted in the driver
  not keeping the hardware queue properly filled when doing non-aggregate
  traffic.  I have a patch to commit soon which fixes this situation
  (albeit by reminding me about how my ath driver locking isn't working
  out, sigh.)

  So if you want to test this without updating to the next set of patches
  that I commit, just bump the sysctl dev.ath.X.hwq_limit from 2 to 32.

Tested:

* AR5416 <-> AR5416, with ampdu disabled, HT40, 5GHz, MCS12+Short-GI.
  I saw 30mbit/sec in both directions using a bidirectional UDP test.

When transmitting non-aggregate traffic, we need to keep the hardware

kill us.

This restores non-aggregate iperf performance, especially when doing
TDMA.

First cut at deferred transmit for the VAP path.

The aim here is to eventually do a hybrid direct dispatch if there's no
transmitter, or a deferred dispatch if the transmitter is currently
busy.  But for now this will just have to do.  It'll add a little more
latency on top of things but it'll at least make things a bit more
sane.

* Create a new vap task for transmit
* Add transmit and qflush for the vap interface; kill the if_start()
  version of the method.
* The transmit/qflush routines still use the vap ifp if_snd queue,
  but they themselves do the packet setup, enqueue and dequeue/dispatch.
  Things are nicely separated enough to hopefully make it easier for me
  to figure out a better, flexible queue+dispatch framework.

What's next:

* Create a different taskqueue, one for each VAP, that handles transmit.
  Sticking it in the ic queue unfortunately serialises the VAP transmit
  with the ic transmit and stops multiple, overlapping VAPs from
  transmitting.  This makes things much easier but it also hides a bunch
  of potential race conditions.  So, let's break things out into a
  race-prone setup which somewhat matches the existing scenario in -HEAD -
  indepedent VAP and driver transmit threads.

* .. it may be that instead of doing per-VAP methods, we do a per-IC
  transmit taskqueue but create a separate one just for transmit.
  That way if the driver wishes to serialise its own software queue
  mechanism with the net80211 transmit path - eg because it wishes to
  allocate its own sequence numbers w/ A-MPDU - then the driver code
  can just keep the global ic vap transmit lock held, rather than trying
  to keep some per-VAP transmit lock held.

* .. and it's still not clear how to setup the TX, node (comlock) and
  driver locking in a way that isn't ugly and/or cause LORs.

* Push frames from the raw transmit path into the VAP path directly,
  rather than doing a call to ic_raw_xmit() from here.  Then the
  dispatch task can decide whether to call the vap transmit method
  or the device ic_raw_xmit method.  Serialising both of these calls
  together will go a long way towards ensuring the driver state is
  kept sane.

* Figure out how to shoehorn management traffic frame generation into
  this.  Right now it grabs the TX path lock and then sets up the
  frame state independent of the VAP transmit path.  It then calls
  ic_raw_xmit().  There's LOR problems doing it this way; it would
  just plain be nicer if we could setup these frames in the caller
  context and then assign 802.11 state (eg sequence number, tag
  with power save info, feed into FF/AMSDU/powersave/etc) state
  from inside the serialised VAP transmit path.

Anyway, still lots to do.

MFC r250327

Add a sysctl vfs.read_min to complement the exiting vfs.read_max.  It
defaults to 1, meaning that it's off.

When read-ahead is enabled on a file, the vfs cluster code deliberately
breaks a read into 2 I/O transactions; one to satisfy the actual read,
and one to perform read-ahead.  This makes sense in low-latency
circumstances, but often produces unbalanced i/o transactions that
penalize disks.  By setting vfs.read_min, we can tell the algorithm to
fetch a larger transaction that what we asked for, achieving the same
effect as the read-ahead but without the doubled, unbalanced transaction
and the slightly lower latency.  This significantly helps our workloads
with video streaming.

Increase the (arbitrary) limit for the number of packets per tick
from 1k to 20k The previous value was good 10 years ago, but not
anymore now.

More importantly, lots of good surprises:
polling is incredibly effective under virtualization, and not only
prevents livelock but also saves most of the VM exit overhead in
receive mode.

Using polling, a FreeBSD instance under qemu-kvm remains perfectly
responsive even when bombed with 10 Mpps over an emulated e1000,
and happily processes 1.7 Mpps through ipfw.

Note that some incompatibilities still remain: e.g. polling is not
(yet) compatible with netmap, and seems to freeze the guest when
kern.polling.idle_poll=1

Fix loss of the emulated keyboard on Xen PV HVM domains.

xen/xenbus/xenbusb.c:
    In xenbusb_probe_children(), do not modify the XenBus state of
    devices for which we have no PV driver support. An emulated device
    we do support may share this backend.  Hide the node from XenBus
    instead.

    This prevents closing the vkbd device, which Qemu's emulated keyboard
    device is using as the source for keyboard events.

    Tested with qemu-xen-traditional, qemu-xen and qemu stubdomains, all
    working as expected.

Switch to AP[2:1] access permissions model. Store "referenced"
bit in PTE.

Enable Access Flag in CPU control. With AF enabled each valid mapping
needs to have referenced bit in PTE set in order to be able to cache
it in the TLB.

AP[0] bit is to be used as reference flag.
All access permissions are encoded by AP[2:1] wherein AP[1] is in fact
"user enable" and AP[2](APX) is "write disable".

All mappings are always set to be valid. Reference emulation is performed
by setting/clearing reference flag in PTE.

md.pvh_attrs are no longer necessary however pv_flags are still being used
for now.

Marking vm_page as "dirty" or "referenced" is being performed on:
- page or flag fault servicing in pmap_fault_fixup(), basing on the fault
  type
- vm_fault servicing in pmap_enter() according to the desired protections
  and faulty access type
Redundant page marking has been removed as on ARM we know exactly when the
particular page is referenced or is going to be written.

Improve, optimize and clean-up ARMv6/v7 memory management related code.

Use pmap_find_pv if needed instead of multiplying its code throughout
pmap-v6.

Avoid possible NULL pointer dereference in pmap_enter_locked()
When trying to get m->md.pv_memattr, make sure that m != NULL,
in particular that vector_page is set to be NULL.

Do not set PGA_REFERENCED flag in pmap_enter_pv().
On ARM any new page reference will result in either entering the new
mapping by calling pmap_enter, etc. or fixing-up the existing mapping in
pmap_fault_fixup().
Therefore we set PGA_REFERENCED flag in the earlier mentioned cases and
setting it later in pmap_enter_pv() is just waste of cycles.

Delete unused pm_pdir pointer from the pmap structure.

Rearrange brackets in the fault cause detection in trap.c
Place the brackets correctly in order to see course of the conditions
instantaneously.

Unify naming in pmap-v6.c and improve style
Use naming common for whole pmap and compatible with other pmaps,
improve style where possible:
pm   -> pmap
pg   -> m
opg  -> om
*pt  -> *ptep
*pte -> *ptep
*pde -> *pdep

Stop using PVF_MOD, PVF_REF & PVF_EXEC flags in pv_entry, use PTE.

Using PVF_MOD, PVF_REF and PVF_EXEC is redundant as we can get the proper
info from PTE bits.
When the mapping is marked as executable and has been referenced we assume
that it has been executed. Similarly, when the mapping is set to be writable
and is referenced, it must have been due to write access to it.
PVF_MOD and PVF_REF flags are kept just for pmap_clearbit() usage,
to pass the information on which bit should be cleared.

Rework and organize pmap_enter_locked() function.

pmap_enter_locked() implementation was very ambiguous and confusing.
Rearrange it so that each part of the mapping creation is separated.
Avoid walking through the redundant conditions.
