This is only a partial merge of respective ZFS infrastructure changes.
At this moment FreeBSD kernel has no those crypto algorithms, so the
parts of the code to enable them are commented out. When they are
implemented, it will be trivial to plug them in.

- If the proxy returns a non-200 result, set the error code accordingly
so the caller / user gets a somewhat meaningful error message.
- Consume and discard any HTTP response header following the result line.

MACHINE_CPUARCH expands to aarch64 for arm64, whereas MACHINE always
corresponds to the directory name under sys/ that contains the sources
for that architecture.
In r204548 the 'rm -f ldscripts' was added likely due to reading the
conditional as 'else it is a file'. That seems unlikely though and
the more likely case is just that the directory hasn't been created yet.
Because this races with ,ssother scripts, use 'mkdir -p' which is a minimal
modification vs upstream to avoid the warning of 'File exists' if another
script creates it first. This could replace the 'test -d' as well but
then it's more unneeded change to the upstream script.

deletions. Ability to do deletions is a strong indication that this
optimization will not help performance. It will only generate extra write
traffic. These devices are typically flash based and have a limited number of
write cycles. In addition, making the file contiguous in LBA space doesn't
improve the access times from flash devices because they have no seek time.

This is a follow-up to r289208: "Xeon Errata Workaround."
Add logic to support a variable number of memory windows and doorbell
callbacks. This was added to the Linux driver in the "Xeon Errata
Workaround" commit, but I skipped it because it didn't look neccessary
at the time. It is needed for future Haswell split-BAR support, so
bring it in now.
A new tunable was added for if_ntb, 'hw.ntb.max_num_clients'. By
default, it is set to zero -- infer the number of clients from the
number of memory windows available from the hardware. Any other
positive value can specify a different number of clients, limited by the
number of doorbell callbacks available (4 under MSI-X, or 15 (Xeon) or
34 (SoC) under legacy INTx).

Before this, if a file was installed to DESTDIR/some/dir and that directory
was missing due to not having ran 'make distrib-dirs' yet, the file would
be installed as 'some/dir'. For something like bsd.incs.mk with INCLUDEDIR
being a sub-directory of /usr/include, this could result in all of the headers
being installed to a file rather than getting a directory of them.
Now it will error that the file/directory does not exist rather than hide
the issue.
Another option being discussed is to implement GNU's install -D flag which
would auto create any missing directories.
This is a mitigation of the problem. The proper order to the build is to
run 'make distrib-dirs' first, but that can be forgotten if building from
a sub-directory after updating the source code to the latest revision.

While trying to get multithreading working for CloudABI on aarch64, I
noticed that compare-and-exchange operations in kernelspace would always
fail. It turns out that we don't properly set the return value to 0 when
the compare and exchange succeeds.

casuword(9) and others, use LDRT and STRT instructions to access
memory with the privileges of userspace. If the *RT instruction
faults on the kernel address, then additional checks must be done to
not confuse the VM system with invalid kernel-mode faults.
Put ARM on line with other FreeBSD architectures and disallow usermode
buffers which intersect with the kernel address space in advance,
before any accesses are performed. In other words, vm_fault(9) is no
longer called when e.g. suword(9) stores to invalid (i.e. not
userspace) address.
Also, switch ARM to use fueword(9) and casueword(9).
Note: there is a pending patch in D3617, which adds the special
processing for faults from LDRT and STRT. The addition of the
processing is useful for potential other uses of the instructions and
for completeness, but standard userspace accessors are better served
by not allowing such faults beforehand.

- video https://www.youtube.com/watch?v=iY44jPMvxog
- manpage changes (for zfs resume -s and zfs send -t)
- upcoming talk at the OpenZFS Developer Summit
The TL;DR is:
Use "zfs receive -s" to save the partially received state on failure.
On failure, get the receive token with "zfs get receive_resume_token <fs>"
Resume the send with "zfs send -t <token_value>"

This patch adds support for the BCM57765[2] card reader function included in
Broadcom's BCM57766 ethernet/sd3.0 controller. This controller is commonly
found in laptops and Apple hardware (MBP, iMac, etc).
The BCM57765 chipset is almost fully compatible with the SD3.0 spec, but
does not support deriving a frequency below 781KHz from its default base
clock via the standard SD3.0-configured 10-bit clock divisor.
If such a divisor is set, card identification (which requires a 400KHz
clock frequency) will time out[1].
As a work-around, I've made use of an undocumented device-specific clock
control register to switch the controller to a 63MHz clock source when
targeting clock speeds below 781KHz; the clock source is likewise switched
back to the 200MHz clock when targeting speeds greater than 781KHz.
Additionally, this patch fixes a small sdhci_pci bug; the
sdhci_pci_softc->quirks flag was not copied to the sdhci_slot, resulting in
`quirk` behavior not being applied by sdhci.c.
[1] A number of Linux/FreeBSD users have noted that bringing up the chipsets'
associated ethernet interface will allow SD cards to enumerate (slowly).
This is a controller implementation side-effect triggered by the ethernet
driver's reading of the hardware statistics registers.
[2] This may also fix card detection when using the BCM57785 chipset, but I
don't have access to the BCM57785 chipset and can't verify.
I actually snagged some BCM57785 hardware recently (2012 Retina MacBook Pro)
and can confirm that this also fixes card enumeration with the BCM57785
chipset; with the patch, I can boot off of the internal sdcard reader.

HWPMC depends on pmu.c even if device pmu is not specified.
Would be great if we could just automatically enabled "device pmu"
if we try to compile in HWPMC.
Also several old kernel cnfigurations seem to have HWPMC enabled but are
pre-FDT and thus fail. So make pmu.c depend on fdt in case of hwpmc as
well.
