This is not exhaustive - DWARF 5 has some new enumeration types not
implemented here - but I think I caught all the ones that are extended
in DWARF 5, plus the new compilation unit type (DW_UT_*), needed when
parsing .debug_info headers.
These were useful when extending libdwarf/ctfconvert/readelf to handle
DWARF generated by gcc 12, which is version 5 by default.

Casting to int truncates size on some platforms, resulting swab not
copying all the data. Cast len to size_t to avoid right shifting a
signed value: we know here it's > 0, so we can safely cast it w/o losing
precision.
In addition, be more careful with signedness of char pointers and
temporaries. Downgrade tmp from unsigned long to unsigned char since
we're only reading and writing characters.

Add missing logic to allow in-kernel VFP usage for ARMv7 NEON.
The implementation is strongly based on arm64 code.
It introduces a family of fpu_kern_* functions to enable the usage
of VFP instructions in kernel.
Apart from that the existing armv7 VFP logic was modified,
taking into account that the state of the VFP registers can now
be modified in the kernel.

When __thr_pshared_offpage() is called for allocation, it must not use
the cached offpage for the key. Instead, the cached offpage must be
unmapped and removed from the cache, if any.
It is legitimate for the user code to unmap the shared lock object without
destroying it, and then mapping something over the freed VA to carry
another shared lock. In this case the cached offpage must be un-cached.

Under Linux to sched_[g|s]etaffinity() functions the value returned from a call
to gettid(2) (thread id) can be passed in the argument pid. Specifying pid as 0
will set the attribute for the calling thread, and passing the value returned
from a call to getpid(2) (process id) will set the attribute for the main thread
of the thread group.
Native cpuset(2) family of system calls has "which" argument to determine how
the value of id argument is interpreted, i.e., CPU_WHICH_TID is used to pass
a thread id and CPU_WHICH_PID - to pass a process id.
For now native sched_[g|s]etaffinity() implementation is wrong as uses "which"
CPU_WHICH_PID to pass both (process and thread id) to the kernel. To fix this
adding a new "which" CPU_WHICH_TIDPID intended to handle both id's.

Since f35093f8 semantics of a thread affinity functions is changed to be a
compatible with Linux:
In case of getaffinity(), the minimum cpuset_t size that the kernel permits is
the maximum CPU id, present in the system, / NBBY bytes, the maximum size is not
limited.
In case of setaffinity(), the kernel does not limit the size of the user-provided
cpuset_t, internally using only the meaningful part of the set, where the upper
bound is the maximum CPU id, present in the system, no larger than the size of
the kernel cpuset_t.
To match pthread_attr_[g|s]etaffinity_np checks of the user-provided cpusets to
the kernel behavior export the minimum cpuset_t size allowed by running kernel
via new sysctl kern.sched.cpusetsizemin and use it in checks.

#14422 x86 assembly: fix .size placement and replace .align with .balign
Obtained from: OpenZFS
OpenZFS commit: 9cd71c8604
The .align directive used to align storage locations is
ambiguous. On some platforms and assemblers it takes a byte count,
on others the argument is interpreted as a shift value. The current
usage expects the first interpretation.
Replace it with the unambiguous .balign directive which always
expects a byte count, regardless of platform and assembler.

In the zstream code, Coverity reported:
"The argument could be controlled by an attacker, who could invoke the
function with arbitrary values (for example, a very high or negative
buffer size)."
It did not report this in the kernel. This is likely because the
userspace code stored this in an int before passing it into the
allocator, while the kernel code stored it in a uint32_t.
However, this did reveal a potentially real problem. On 32-bit systems
and systems with only 4GB of physical memory or less in general, it is
possible to pass a large enough value that the system will hang. Even
worse, on Linux systems, the kernel memory allocator is not able to
support allocations up to the maximum 4GB allocation size that this
allows.
This had already been limited in userspace to 64MB by
`ZFS_SENDRECV_MAX_NVLIST`, but we need a hard limit in the kernel to
protect systems. After some discussion, we settle on 256MB as a hard
upper limit. Attempting to receive a stream that requires more memory
than that will result in E2BIG being returned to user space.

Introduce four new vdev properties:
checksum_n
checksum_t
io_n
io_t
These properties can be used for configuring the thresholds of zed's
diagnosis engine and are interpeted as <N> events in T <seconds>.
When this property is set to a non-default value on a top-level vdev,
those thresholds will also apply to its leaf vdevs. This behavior can be
overridden by explicitly setting the property on the leaf vdev.
Note that, these properties do not persist across vdev replacement. For
this reason, it is advisable to set the property on the top-level vdev
instead of the leaf vdev.
The default values for zed's diagnosis engine (10 events, 600 seconds)
remains unchanged.

This allows parsing of zfs send progress by checking the process

Doing so requires some changes to the send code in libzfs_sendrecv.c;
primarily these changes move some of the accounting around, to allow
for the code to be verbose as normal, or set the process title. Unlike
BSD, setproctitle() isn't standard in Linux; thus, borrowed it from

Cast char's through unsigned char before storing as an integer in
xdr_char(), this ensures that the encoded form is consistently not
sign-extended following Open Solaris's example.
Prior to this change, platforms with signed chars would sign extend
values with the high bit set but ones with unsigned chars would not
so 0xff would be stored as 0x000000ff on unsigned char platforms and
0xffffffff on signed char platforms. Decoding has the same
result for either form so this is a largely cosmetic change, but it
seems best to produce consistent output.
