riscv: Avoid passing invalid addresses to pmap_fault()
After the addition of SV48 support, VIRT_IS_VALID() did not exclude
addresses that are in the SV39 address space hole but not in the SV48
address space hole. This can result in mishandling of accesses to that
range when in SV39 mode.
Fix the problem by modifying VIRT_IS_VALID() to use the runtime address
space bounds. Then, if the address is invalid, and pcb_onfault is set,
give vm_fault_trap() a chance to veto the access instead of panicking.

On physical systems the ram isn't initialized on boot. So, coreboot uses
the cache as ram in this boot phase. When exiting cache as ram, coreboot
calls INVD for making the cache consistent.
In a virtual environment ram is always initialized and the cache is
always consistent. So, we can safely ignore this call.

While in theory, once upon a time, dv_type was arch specific, that's
never been the case in FreeBSD (and certaintly isn't in the surviving
drivers). Remove that notation.
Currently there is no upper bound on the PMTU value that is accepted.
Update hostcache only if the new pmtu is smaller than the current entry
and the link MTU.
Currently we accept any pmtu between IPV6_MMTU(1280B) and the link mtu.
In some network topologies could allow a bad actor to perform a DOS attack.
Contrary to IPv4 in IPv6 oversized packets are dropped, and a ICMP
PACKET_TOO_BIG message is sent back to the sender.
After receiving an ICMPv6 packet with pmtu bigger than the
current one the victim will start sending frames that will be dropped
a router with reduced MTU.
Although it will eventually receive another message with correct pmtu,
an attacker can still just inject their spoofed packets frequently
enough to overwrite the correct value.
This issue is described in detail in RFC8201, section 6.
Fix this by checking the current pmtu, and accepting the new one only
if it's smaller.

sbin/md5.c: fix -q -c for BSD style versions
The BSD style commands (with names not ending in "sum") ignored the -c
options and the passed digest value when invoked with -q.
The man page stated that -q causes only the calculated digest to be
printed, but did not consider the case of both the -q and -c being
used in combination.
Since there is no warning that -c will be ignored when the -q option
is used, users night (and did) expect that the exit code would reflect
the matching of the calculated digest and the argument passed with -c.
This update implements and documents this expected behavior.

The 'sent' variable was used in the for loop later in the

libcrypto: Work around strict aliasing violations in bn_nist.c
This file is full of strict aliasing violations. Previously it was only
optimised in ways that broke the code by CHERI LLVM, but now it appears
that the in-tree LLVM also breaks it for RISC-V, resulting in broken
ECDSA signature validation with error messages like the following:
root@unmatched:/usr/src # ssh-keygen -l -f /etc/ssh/ssh_host_ecdsa_key
/etc/ssh/ssh_host_ecdsa_key is not a key file.
root@unmatched:/usr/src # git fetch

iommu_gas: Eliminate a possible case of use-after-free
Eliminate a possible case of use-after-free in an error handling path
after a mapping failure. Specifically, eliminate IOMMU_MAP_ENTRY_QI_NF
and instead perform the IOTLB invalidation synchronously. Otherwise,
when iommu_domain_unload_entry() is called and told not to free the
IOMMU map entry, the caller could free the entry before dmar_qi_task()
is finished with it.

Add ELFCOMPRESS_ZSTD ELF compression constant
ELFCOMPRESS_ZSTD indicates that an ELF section is compressed with zstd.
It is the second compression type, after the existing ELFCOMPRESS_ZLIB.
Zstd generally provides a compelling tradeoff of speed and compression
(other algorithms may compress slightly better but take a lot longer,
or run faster but do not compress nearly as well).
See https://groups.google.com/g/generic-abi/c/satyPkuMisk for details.
ELFCOMPRESS_ZSTD will be supported in a future Clang/LLVM update. ELF
Tool Chain tools also need updating.

Add d_sblockloc to libufs(3) disk structure to allow options to be added.
By making the disk block parameter used by the libufs(3) sbread(3)
function visible, applications using sbread(3) can set their own
addition options such as using the STDSB_NOHASHFAIL request to
say that they want the superblock read to succeed even when
the superblock checkhash is incorrect.
While here also add an error message when a check-hash failure
is detected.

stand/libsa: zfs use standard ZFS_EARLY stuff
Now that the minor issues preventing zfs.c from using CFLAGS_EARLY have
been fixed, use that mechanism like everything else that needs the
OpenZFS spl headers. This simplifies things somewhat. Update comments to
document why zfs.c is still special, though in different ways.
Note: We also use the fact that NEED_SOLARIS_BOOLEAN is only defined in
an environment where the solaris compat boolean stuff will be defined
prior to this point (eg, when we're building zfs.c in libsa), but not in
other environments (like when we're building mkimage and stand-alone
boot loaders that don't use libsa). These latter uses should be changed
to use the same ZFS compile env, but aren't as part of this commit.
This has to be done in the same change as the ZFS_EARLY change to not
break zfs.c building for one commit affecting bisectabiltiy.

zfs: Increase compatibility for different environments
libsa uses the full OpenZFS compilation environment when we build this
included in zfs.c there. Other parts of the tree have not been adapted
to the full OpenZFS environment yet and need these ASSERT* defines to
build properly. Since the ASSERT* macros are normally defined in
sys/debug.h in the OpenZFS compatibility spl, only define them when
ASSERT3S is not defined to cope with the parts of the loader that don't
yet use the full OpenZFS environment.

OpenZFS changed the define _OPENSOLARIS_SYS_TYPES_H_ to

_OPENSOLARIS_SYS_TYPES_H_ is mentioned is in the /*

stand/zfs: Limit flags further for ZFS
Constrain CFLAGS for ZFS: don't add anything globally. Add the includes
to only the files that need them. Add -DHAS_ZSTD_ZFS to zfs.c (which
includes zfsimpl.c which includes zfssubr.c both of which need this
defined). Also add it to efi/boot1/Makefile since zfs_module.c also
includes zfsimple.c.
