MFC r208453:
Reorganize syscall entry and leave handling.
Implement ptrace_lwpinfo pl_flags PL_FLAG_SCE, PL_FLAG_SCX and
PL_FLAG_EXEC.

The i386, amd64, sparc64, sun4v, powerpc and ia64 syscall()s are
changed to use syscallenter()/syscallret(). MIPS and arm are not
converted and use the mostly unchanged syscall() implementation.

MFC r208514:
Change ia64' struct syscall_args definition so that args is a pointer to
the arguments array instead of array itself.

MFC r208566:
Allow to use syscallname(9) outside subr_trap.c.

MFC r209258 (by rpaulo):
Make DTrace syscall provider work again by including opt_kdtrace.h here.

MFC r209313:
Only enable kdtrace hook in the LINT on the architectures that implement it.

MFC r209697:
Obey sv_syscallnames bounds in syscallname().

NOTE: The KBI of the struct sysentvec is changed, new required members
sv_set_syscall_retval, sv_fetch_syscall_args and sv_syscallnames are
added. The sv_prepsyscall field is now ignored. Third-party modules
using the struct sysentvec must be modified and recompiled, we believe
that only ABI emulators are affected. No such out-of-tree modules are
known. In-tree modules that are affected by the change were converted
to depend on exact version of the kernel, see r214421.

Modify the experimental NFSv4 server's file handle hash function
to use the generic hash32_buf() function. Although adding the
bytes seemed sufficient for UFS and ZFS, since most of the bytes
are the same for file handles on the same volume, this might not
be sufficient for other file systems. Use of a generic function
also seems preferable to one specific to NFSv4.

Bug Fix
=======
Since $build_l is no longer being incremented prior to the user's
+IGNOREME decision it's no longer necessary to decrement it if the
user chooses not to update that port.

While I was reading the trace to find this bug I noticed that we are
running update_build_l (which in turn updates PM_NEEDS_UPDATE) prior
to running check_state (FORBIDDEN|DEPRECATED|BROKEN|IGNORE), so move
that check up; and move the "currently installed" and "port directory"
messages up as well to give context to any messages from check_state.

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

In r214728, if dlopen() is called for the object that has been already
loaded as a dependency and marked -z nodlopen, object' DAG is already
initialized by load_needed_objects(). Due to this, the init_dag() call
from dlopen() does not increment refcount for the object [1].

Change init_dag() to not increment DAG refcount. Require explicit calls
to ref_dag() to increment, and assert that ref_dag() and unref_dag()
are called for root that has dag initialized. To fix the noted issue,
unconditionally call both init_dag() and ref_dag() in dlopen() for the
case when the object was already loaded, making it similar to the case
of newly loaded object.

Binutils commit 0c845abb5a0083c6deebc75975608237015badba increased
ELF_MAXPAGESIZE for amd64 from 0x00100000 to 0x00200000.  This caused
the kernel to be incorrectly linked, using the existing linker script,
resulting in a virtual address of 0xffffffff80000000 for the LOAD
program header.

The boot loader will load such a kernel at a real address of 0x00000000,
which either causes protection faults in btx, crashes the machine, or
(in case of a VMware guest) even makes it power down. :)

Fix this by partially synchronizing the amd64 linker script with
binutils own updated version, in particular replacing a hardcoded
value of 0x00100000 by CONSTANT(MAXPAGESIZE).

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.

Introduce a bit flag UMUTEX_SIMPLE for umutex, so that it does not use thread id
to lock and unlock. this is necessary, because a link entry can not be embedded
into mutex which will be shared between processes, because if other process do
incorrect think, it corrupt your link list.
But to let unlocking after fork() to work, we either should link it into list
to remember it or use a id which can be atomatically duplicated.
We use pthread pointer, the bit UMUTEX_SIMPLE_OWNER indicates if the mutex is
locked or unlocked.

Now following the change in kernel, we use UMUTEX_SIMPLE bit flag to avoid
use thread id from process-private mutex, so we don't need to link mutex
into list, this saves some cycles. Not that for priority-protect mutex, we
still need to link it, because we should restore correct priority after
unlocking a such kind of mutex. Also the priority-inhertied mutex needs to
be linked, because we still use thread ID as lock-word.
The simplest mutex is now a bit faster then before.

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.

Add simple MAC statistics counter reading support. Unfortunately
useful counters like rl_missed_pkts is 16 bits quantity which is
too small to hold meaningful information happened in a second. This
means driver should frequently read these counters in order not to
lose accuracy and that approach is too inefficient in driver's
view. Moreover it seems there is no way to trigger an interrupt to
detect counter near-full or wraparound event as well as lacking
clearing the MAC counters. Another limitation of reading the
counters from RealTek controllers is lack of interrupt firing at
the end of DMA cycle of MAC counter read request such that driver
have to poll the end of the DMA which is a time consuming process
as well as inefficient. The more severe issue of the MAC counter
read request is it takes too long to complete the DMA. All these
limitation made maintaining MAC counters in driver impractical. For
now, just provide simple sysctl interface to trigger reading the
MAC counters. These counters could be used to track down driver
issues. Users can read MAC counters maintained in controller with
the following command.
#sysctl dev.re.0.stats=1

While I'm here add check for validity of dma map and allocated
memory before unloading/freeing them.

MFC r213913:

Retire the system-wide, per-reassembly queue segment limit. The mechanism is far
too coarse grained to be useful and the default value significantly degrades TCP
performance on moderate to high bandwidth-delay product paths with non-zero loss
(e.g. 5+Mbps connections across the public Internet often suffer).

Replace the outgoing mechanism with an individual per-queue limit based on the
number of MSS segments that fit into the socket's receive buffer.  This should
strike a good balance between performance and the potential for resource
exhaustion when FreeBSD is acting as a TCP receiver. With socket buffer
autotuning (which is enabled by default), the reassembly queue tracks the socket
buffer and benefits too.

As the XXX comment suggests, my testing uncovered some unexpected behaviour
which requires further investigation. By using so->so_rcv.sb_hiwat instead of
sbspace(&so->so_rcv), we allow more segments to be held across both the socket
receive buffer and reassembly queue than we probably should. The tradeoff is
better performance in at least one common scenario, versus a devious sender's
ability to consume more resources on a FreeBSD receiver.

Instead of using the AMRR ratectl algo as default for drivers which have
the IEEE80211_C_RATECTL flag set, default to NONE for all drivers. Only if
a driver calls ieee80211_ratectl_init() check if the NONE algo is still
selected and try to use AMRR in that case. Drivers are still free to use
any other algo by calling ieee80211_ratectl_set() prior to the
ieee80211_ratectl_init() call.

After this change it is now safe to assume that a ratectl algo is always
available and selected, which renders the IEEE80211_C_RATECTL flag pretty
much useless. Therefore revert r211314 and 211546.

If we got an invalid station address, generate random address. This
might be caused by broken BIOS.

Fix a long standing bug in programming station address for Yukon
controllers. sk(4) never reprogrammed station address for Yukon
controllers so overriding station address with ifconfig(8) was not
possible.
Fix the bug by reprogramming all registers that control station
address, flow-control and virtual station address. Virtual station
address has no use at this moment since driver does not make use of
fail over feature.

Remove siis.4 from the man4/Makefile. It was incorrectly included in r214875 as
part of the SIFTR MFC and breaks buildworld as siis.4 doesn't exist in stable/7.

This is an intentional direct commit to the 7-STABLE branch.

If the Zip reader doesn't see a PK signature block
because there's inter-entry garbage, just scan forward
to find the next one.  This allows us to handle a lot
of Zip archives that have been modified in-place.

Thanks to: Gleb Kurtsou for sending me a sample archive
