Now that aw_sid expose nvmem interface, use that to read the calibration
data.
Add support for H5 SoC.
Fix the bindings, we used to have non-upstreamed bindings. Switch to the
one that have been sent upstream. They are not stable yet, so we switch
from custom, wrong, bindings to correct, proposed bindings
Rework aw_sid so it can work with the nvmem interface.
Each SoC expose a set of fuses (for now rootkey/boardid and, if available,
the thermal calibration data). A fuse can be private or public, reading private
fuse needs to be done via some registers instead of reading directly.
Each fuse is exposed as a sysctl.
For now leave the possibility for a driver to read any fuse without using
the nvmem interface as the awg and emac driver use this to generate a mac
address.
Other architectures are documented in terms of the name that is displayed by
'uname -p', aka MACHINE_ARCH and TARGET_ARCH in the build system, now
aarch64 matches the rest of them.

At least on x86, fhandle_t is a packed structure, so I believe an
assignment will copy all the bits. However, for some current/future
architectures, there might be padding in the structure that doesn't get
copied via an assignment.
Since NFS assumes a file handle is an opaque blob of bits that can be
compared via memcmp()/bcmp(), all the bits including any padding must be
copied.
This patch replaces the assignments with a call to a byte copy function.
Spotted during code inspection.
Since bd_open() does early increment for reference counter and bcache
allocation, it also should undo those in case of the error.
Also remove unused variables rdev, g_err.
On a FreeNAS mini XL, with geli encrypted drives the loader crashed in
geli_read().
When we iterate over the list of disks and allocate the zfsdsk structures we
don’t zero out the gdev pointer. In one case that resulted in geli_read()
(called on the bogus pointer) dividing by zero.
Use calloc() to ensure the zfsdsk structure is always zeroed, so the pointer is
initialised to NULL. As a side benefit it gets rid of one #ifdef
LOADER_GELI_SUPPORT.
To compile this driver with evdev support enabled, place
following lines into the kernel configuration file:
options EVDEV_SUPPORT
device evdev
Note: Native and evdev modes are mutually exclusive.

We didn't allowed a divider register value of 0 which can exists and
also didn't wrote the value but the divider, which result of a wrong

It doesn't work since 2 years when we stopped patching DTS.
The DTS now have the correct bindings but they are a lot different
from our hacked ones we used to have (and more representative of the
reality).
Remove the old clocks for allwinner as now all the SoCs have been converted
to clkng.
The only old clock now is the gmac clock which still lives under the /clocks
dts node.
Contrary to the removed comment, the kernel does appear to use the timezone
argument of settimeofday. The comment dates to the BSD4.4 import; I assume it
is just stale.
efi_enter here was needed because efi_runtime dereference causes a fault
outside of EFI context, due to runtime table living in runtime service
space. This may cause problems early in boot, though, so instead access it
by converting paddr to KVA for access.
While here, remove the other direct PHYS_TO_DMAP calls and the explicit DMAP
requirement from efidev.

Swapped-out process that is WKILLED must be swapped in as soon as
possible. The reason is that such process can be killed by OOM and
its pages can be only freed if the process exits. To exit, the kernel
stack of the process must be mapped.
When allocating pages for the stack of the WKILLED process on swap in,
use VM_ALLOC_SYSTEM requests to increase the chance of the allocation
to succeed.
Add counter of the swapped out processes to avoid unneeded iteration
over the allprocs list when there is no work to do, reducing the
allproc_lock ownership.

With r337328, the test hangs becase the sendmsg() call will block until
the receive buffer is at least partially drained. Fix the problem by
using a non-blocking socket and allowing short writes. Also assert
that a SCM_CREDS message was received if one was expected.

sosend_generic() performs an initial comparison of the amount of data
(including control messages) to be transmitted with the send buffer
size. When transmitting on a unix socket, we then compare the amount
of data being sent with the amount of space in the receive buffer size;
if insufficient space is available, sbappendcontrol() returns an error
and the data is lost. This is easily triggered by sending control
messages together with an amount of data roughly equal to the send
buffer size, since the control message size may change in uipc_send()
as file descriptors are internalized.
Fix the problem by removing the space check in sbappendcontrol(),
whose only consumer is the unix sockets code. The stream sockets code
uses the SB_STOP mechanism to ensure that senders will block if the
receive buffer fills up.

This is because on i386, several casts from `uint64_t` to a pointer
reduce the value from 64 bit to 32 bit.
For gcc, this can be fixed by an intermediate cast to uintptr_t. Note
that I am assuming the incoming values will always fit into 32 bit!

Usbhid's hid_report_size() calculates integral size of all reports of given
kind found in the HID descriptor rather then exact size of report with given
ID as its userland counterpart does. As all input data processed by the
driver is located within the same report, calculate required driver's buffer
size with userland version, imported in one of the previous commits.
This allows us to skip zeroing of buffer on processing of each report.
While here do some minor refactoring.

efi-autoresizecons is currently executed for every boot. If it fails, we
risk failing the boot, and we really shouldn't do that unless we absolutely
must.
Not being able to locate GOP or UGA is not a significant enough failure to
kill the boot. We always have the option to fall back to resizing ConOut to
a higher text mode resolution (if available), so do that.
This was detected by Doug [1] while attempting a bhyve + UEFI + PXE boot.
This patch was effectively also submitted by Doug, but I expanded the
comment he had originally sent me a little bit to indicate why this is an OK
idea.

The links were to cope with the switch to upstream dts.
We don't need them anymore.
While here add the rest of the beaglebone family dts as u-boot is common
on all those boards and load the dtb based on the product name.
This just miss the pocketbeagle variant as it's not yet in sys/gnu/dts but
will be with the Linux 4.18 dts import.
