* include/bits/stl_multimap.h (multimap<>::multimap(_InputIterator,
_InputIterator)): Forward to _M_insert_equal, not _M_insert_unique.
This patch was GPL2 at the time and fixes a regression introduced with
the merge of GCC r129013 in FreeBSD r236829.

platforms which do not use loaders or kernels that want to hardcode
options or for FDT passed in by loader.
Also fix a build issue by putting the kmdp variable accessed back under
the #ifdef FDT; we may wish to revisit decision in which case more
code needs changing.

by adding an argument to the VM_SUSPEND ioctl that specifies how the virtual
machine should be suspended, viz. VM_SUSPEND_RESET or VM_SUSPEND_POWEROFF.
The disposition of VM_SUSPEND is also made available to the exit handler
via the 'u.suspended' member of 'struct vm_exit'.
This capability is exposed via the '--force-reset' and '--force-poweroff'
arguments to /usr/sbin/bhyvectl.

The sysctl may be removed again after r263758 has been merged to at

Instead opening/closing provider by each of metadata classes, do it only
once in core code. Since for SCSI disks open/close means sending some
SCSI commands to the device, this change reduces taste time.

FD_SETSIZE is often used as an argument to select or compared with an
integer file descriptor. Rather than force 3rd party software to add
explicit casts, just make it a plain (int) constant as on other
operating systems.

returns ZIO_PIPELINE_CONTINUE from vdev_op_io_start to zio_execute resulting
in the wrong ZIO continuing its pipeline.
This is a serious issue which could cause data loss / corruption but appears
to be limited to error handling such as when vdev_readable(vd) returns false.

The QCA HAL has a comment noting that if this isn't done, modifications
to AR_IMR_S2 before AR_IMR is flushed may produce spurious interrupts.

Flushing the caches is required before doing a panic dump, but ARM
doesn't provide a flavor of flush that gets broadcast to other cores.
However, all cores except one are stopped before doing a dump, so this
works around the lack of a global flush/invalidate by doing it locally
on each CPU as part of stopping.

This was added ca. 2004 for the purpose of ensuring the caches were in the
right state after the debugger set a breakpoint. kdb_cpu_sync_icache()
was added in 2007 to handle that situation, and now the wbinv_all is
actually harmful because the operation isn't broadcast to other cores.
* memory is now allocated as early as possible, without holding locks.
* sysctl users are now guaranteed to get a response (M_WAITOK buffer prealloc).
* socket users are more likely to use on-stack buffer for replies.
* standard kernel malloc/free functions are now used instead of radix wrappers.
rt_msg2() has been renamed to rtsock_msg_buffer().

On head/, or more specifically, when WITNESS is in
the kernel config, the console is spammed excessively
with lock order reversal between isofs and devfs.
Set debug.witness.trace=0 in the installer sysctl.conf
to avoid printing the full KDB stack backtrace. This
does not prevent printing the lock order reversal has
happened, only lessens the console spam.

#gpio-cells property.
Add a new ofw_bus method (OFW_BUS_MAP_GPIOS()) that allows the GPIO
controller to implement its own mapping to deal with gpio-specifiers,
allowing the decoding of gpio-specifiers to be controller specific.
The default ofw_bus_map_gpios() decodes the linux standard (#gpio-cells =
<2>) and the FreeBSD standard (#gpio-cells = <3>).
It pass the gpio-specifier flag field to the children as an ivar variable so
they can act upon.
checks for special pcid values in invlpg_pcid_handler(). Forst check
for special values, and only then do PCID-specific page invalidation.
Minor fix to the style compliance, declare local variable at the
function start.

explicitely linking main binary with -lpthread. Before, libthr
appeared in the list due to dependency of one of the kerberos libs.
Due to the change in ld(1) behaviour of not copying NEEDED entries
from direct dependencies into the link results, the order becomes
reversed.
The libthr must appear before libc to properly interpose libc symbols
and provide working rtld locks implementation. The symptom was sshd
hanging on rtld bind lock during nested symbol binding from a signal
handler.

entry and performs the upgrade of the entry permissions from read-only
to read-write, we must allow to search for the source pages in the
backing object, like we do in the case of forking the read-only wired
entry. For the fork case, the behaviour is allowed by src_readonly
boolean, which in fact is only used to assert that read-write case
provides all source pages in the top-level object.
Eliminate the src_readonly variable. Allow for the copy loop to look
into the backing objects, add explicit asserts to ensure that only
read-only and upgrade case actually does.
Expand comments. Change the panic call into assert.
