if they bind directly. There are severe performance penalties for
handling interrupts on remote CPUs and this should only be done in
very controlled circumstances.

Includes our local patch to conditionalize use of __builtin_clz(ll) on
Clang's __has_builtin() (which is just defined to false when building with
GCC).
The issue is tracked upstream at https://github.com/facebook/zstd/pull/884 .
Otherwise, these are vanilla Zstandard 1.3.4 files.

No functional change for Skipjack, AES-ICM, Blowfish, CAST-128, Camellia,
DES3, Rijndael128, DES. All of these have identical IV and blocksizes
declared in the associated enc_xform.
Functional changes for:
* AES-GCM: block len of 1, IV len of 12
* AES-XTS: block len of 16, IV len of 8
* NULL: block len of 4, IV len of 0
For these, it seems like the IV specified in the enc_xform is correct (and
the blocksize used before was wrong).
Additionally, the not-yet-OCFed cipher Chacha20 has a logical block length
of 1 byte, and a 16 byte IV + nonce.
Rationalize references to IV lengths to refer to the declared ivsize, rather
than declared blocksize.

To fix the GCC build, remove multiple redundant declarations of
vmci_send_datagram() (the copy in vmci.h as well as the extern definition in
vmci_queue_pair.c were wholly redundant).
Also to fix the GCC build, include a non-empty format string in the vmci(4)
definition of ASSERT(). It seems harmless either way, but adding the
stringified invariant is easier than masking the warning.
The other vmci_kernel_defs.h changes are cosmetic and simply match macros to
existing definitions.

It was previously only printed, but we do actually want to raise it as a
full blown error so that things don't look OK when they've actually gone
wrong.
The second parameter to error, level, is set to 2 here so that the error
message reflects the position of the try_include caller, rather than the
try_include itself. Example:
LUA ERROR: /boot/lua/loader.lua:46: /boot/lua/local.lua:1: attempt to call a
nil value (global 'cxcint').
This provides a way to optionally include a module without having to wrap it
in filesystem checks. try_include is a little more robust, using the lua
search path instead of forcing us to explicitly consider all of the places
we could want to include a module. Errors are still generally raised from
trying to load the module, but ENOENT will not get raised unless we're doing
a verbose load.
This will also be used to split out logo/brand graphics into their own files
so that we can safely scale up the number of graphics included without
worrying about the extra memory consumption- opting to lazily load graphics
instead.

We must not sleep or acquire any MI VM locks if TDP_NOFAULTING is
specified. On the other hand, there were some callers in the tree
which set TDP_NOFAULTING for larger scope than needed, I fixed the
code which I wrote, but I suspect that linuxkpi and out of tree drm
drivers might abuse this still.
So only enable the mode for vm_fault_quick_hold_pages() where
vm_fault_hold() is not called when specifically asked by user. I
decided to use vm_prot_t flag to not change KPI. Since number of
flags in vm_prot_t is limited, I reused the same flag which was
already consumed for vm_map_lookup().

In a virtual machine, VMCI is exposed as a regular PCI device. The primary
communication mechanisms supported are a point-to-point bidirectional
transport based on a pair of memory-mapped queues, and asynchronous
notifications in the form of datagrams and doorbells. These features are
available to kernel level components such as vSockets through the VMCI
kernel API. In addition to this, the VMCI kernel API provides support for
receiving events related to the state of the VMCI communication channels,
and the virtual machine itself.

DTB Overlays are useful to change/add nodes to a dtb without the need to
modify it.
Add support for building dtbo during buildkernel.
The goal of DTBO present in the FreeBSD source tree is to fill a gap in
time when we submit changes upstream (Linux). Instead of waiting 2 to 4 months
we can add a DTBO in tree in the meantime.
This is not for adding DTBO for capes/hat/addon boards, those will be
better to put in a ports.
This is also not for enabling a i2c/spi/pwm controller on certain pins,
each user have a different use case for those (which pins to use etc ...)
and we cannot have all possible configuration.
Add a dtbo for sun8i-h3-sid which add the SID node missing in upstream dts.

Current code, which copies the potential syscall arguments into the
current frame, puts an arbitrary limit on the number of syscall
arguments. Apparently, mmap(2) and lseek(2) (?) require larger
number. But there is an issue that stack is only need to be mapped to
contain the number of arguments required by the syscall, so copying
arbitrary large number of words from the stack is not completely safe.
Use different approach to convert lcall frame into int $0x80 frame in
place, by doing the retl in kernel. This also allows to stop proceed
vfork case specially, and stop making assumptions about %cs at the
syscall time.
Also, improve comments with the formulations provided by bde.
