Use uintptr_t to cast a uint64_t to a pointer type.
Yeah, it isn't technically correct for platforms with pointers
> 64 bits, but it's fine here.
This fixes 32 bit compat library builds on amd64 and also
mips32 builds.

Use the native vnode lookup functions, instead of going via the LinuxKPI,
because the file referenced is typically created outside the LinuxKPI, and
the LinuxKPI's fdget() can only resolve file descriptor numbers which
were created by itself.
The vnode pointer is used as an identifier to identify XRCD handles which
are sharing resources.
This patch fixes the so-called XRCD support in ibcore for FreeBSD.
Refer to ibv_open_xrcd(3) for more information how the file descriptor
argument is used.

The multipage alignment requirements is incompatible with many aspects
of actual busdma code. Multi-page alignment requests are incompatible
with many aspects of current busdma code. Mainly with partially bounced
buffer segments and per-page loop in bus_dmamap_load_buffer(). Because
proper implementation would be a major restructuring of the code, add
the fix only for already known uses and do KASSERT for all other cases.
For this reason, bus_dmamap_load_buffer () should take the memory allocated
by bus_dmam_alloc () as one segment bypassing per page segmentation. We can
do this because it is guaranteed that the memory is physically continuous.

This sysctl value had been provided as a read-only variable that is
compiled into the C library based on the value of _PATH_LOCALBASE in
paths.h.
After this change, the value is compiled into the kernel as an empty
string, which is translated to _PATH_LOCALBASE by the C library.
This empty string can be overridden at boot time or by a privileged
user at run time and will then be returned by sysctl.
When set to an empty string, the value returned by sysctl reverts to
_PATH_LOCALBASE.
This update does not change the behavior on any system that does
not modify the default value of user.localbase.
I consider this change as experimental and would prefer if the run-time
write permission was reconsidered and the sysctl variable defined with
CLFLAG_RDTUN instead to restrict it to be set at boot time.

Matching table format is compatible with ACPI_ID_PROBE bus method.
Note that while ACPI_ID_PROBE matches against _HID and all _CIDs, current
acpi_pnpinfo_str() exports only _HID and first _CID. That means second
and further _CIDs should be added to both acpi_pnpinfo_str() and
ACPICOMPAT_PNP_INFO if device matching against them is required.

The use of atomic_sub_64() in zfs_zstd.c was breaking the 32-bit build on
platforms without native 64-bit atomics due to atomic_sub_64() not being
available, and no fallback being provided in _STANDALONE.
Provide a standalone stub to match atomic_add_64() using simple math.
While this is not actually atomic, it does not matter in libsa context,
since it always runs single-threaded and does not run under a scheduler.

zstd: track allocator statistics
Note that this only tracks sizes as requested by the caller.
Actual allocated space will almost always be bigger (e.g., rounded up to
the next power of 2 or page size). Additionally the allocated buffer may
be holding other areas hostage. Nonetheless, this is a starting point
for tracking memory usage in zstd.

Add line number information to more warning and error messages.
Detect #else and #endif without corresponing #ifdef/#ifndef as error.
Detect missing #endif at end of file and print warning but continue.
Support for #undef has been added to reverse the effect of a prior #define.
It is no error if the argument value has not been defined before.
These changes may cause error aborts on malformed input files (e.g. with
spurious #else or #endif), but no such errors exist in the calendar files
in the FreeBSD base system and the calendar-data port and all tests pass.
More tests will be added in a follow-up commit to detect regressions that
might affect the newly added features.
This commit ends a series of updates that enhance the pre-processor and
make it behave much more like prior versions of the calendar progarm that
called cpp to pre-process the data files.

Prior versions of FreeBSD (11.x) may have produced a corrupt extattr file.
(Specifically, r312416 accidentally fixed this defect by removing a strcpy.)
CURRENT FreeBSD supports disk images from those prior versions of FreeBSD.
Validate the internal structure as soon as we read it in from disk, to
prevent these extattr files from causing invariants violations and DoS.
Attempting to access the extattr portion of these files results in
EINTEGRITY. At this time, the only way to repair files damaged in this way
is to copy the contents to another file and move it over the original.
