Use the existing PMC_CPUID_LEN to size pmc_cpuid in the kernel and various
buffers for reading it in libpmc. This avoids some extra syscalls and
malloc/frees.
While in here, use strlcpy to copy a user-provided cpuid string instead of
memcpy, to make sure we terminate the buffer.

A base system OpenSSH update in 2016 or so removed a number of ciphers
from the default lists offered by the server/client, due to known
weaknesses. This caused POLA issues for some users and prompted
PR207679; the ciphers were restored to the default lists in r296634.
When upstream removed these ciphers from the default server list, they
moved them to the client-only default list. They were subsequently
removed from the client default, in OpenSSH 7.9p1.
The change has persisted long enough. Remove these extra ciphers from
both the server and client default lists, in advance of FreeBSD 13.

APEI allows platform to report different kinds of errors to OS in several
ways. We've found that Supermicro X10/X11 motherboards report PCIe errors
appearing on hot-unplug via this interface using NMI. Without respective
driver it ended up in kernel panic without any additional information.
This driver introduces support for the APEI Generic Hardware Error Source
reporting via NMI, SCI or polling. It decodes the reported errors and
either pass them to pci(4) for processing or just logs otherwise. Errors
marked as fatal still end up in kernel panic, but some more informative.
When somebody get to native PCIe AER support implementation both of the
reporting mechanisms should get common error recovery code. Since in our
case errors happen when the device is already gone, there is nothing to
recover, so the code just clears the error statuses, practically ignoring
the otherwise destructive NMIs in nicer way.

This constant is only used to size an array within the kernel. There are
probably no legitimate uses in userland. Worse, since the kernel's array
could theoretically change size over time, any use of that symbol in
userland wouldn't be forwards compatible to new kernel versions.

trying to set it.
r362490 added support for setting of the TimeCreate (va_birthtime) attribute,
but it does so without checking to see if the server supports the attribute.
This could result in NFSERR_ATTRNOTSUPP error replies to the Setattr operation.
This patch adds code to check that the server supports TimeCreate before
attempting to do a Setattr of it to avoid these error returns.
r362490 marked that the NFSv4 attribute TimeCreate (va_birthtime) is supported,
but it did not change the NFS server code to actually do it.
As such, errors could occur when unrolling a tarball onto an NFSv4 mounted
volume, since setting TimeCreate would fail with a NFSERR_ATTRNOTSUPP reply.
This patch fixes the server so that it does TimeCreate and also makes
sure that TimeCreate will not be set for a DS file for a pNFS server.
A separate commit will add a check to the NFSv4 client for support of
the TimeCreate attribute before attempting to set it, to avoid a problem
when mounting a server that does not support the attribute.
The failures will still occur for r362490 or later kernels that do not
have this patch, since they indicate support for the attribute, but do not
actually support the attribute.
The caller from kernel is expected to provide an valid g_class
pointer, instead of traversing the global g_class list, just
use that pointer directly instead.

import in 1994, and was a bit misleading (not all arches use simulated
reference bits, some implement reference tracking in hardware).
QEMU's RISC-V virt machine provides syscon-power and syscon-reset
devices as the means by which to shutdown and reboot. We also need to
ensure that we have attached the syscon_generic device before attaching
any syscon_power devices, and so we introduce a new riscv_syscon device
akin to aw_syscon added in r327936. Currently the SiFive test finisher
is used as the specific implementation of such a syscon device.

On RISC-V, Clang warns with:
cast to smaller integer type 'unsigned int' from 'void (*)(void *)'
Instead, use %p as the standard format specifier for printing pointers.
Whilst Arm's pointer size is the same as unsigned, it's still cleaner to
use the right thing there too.

This patch uses a slightly different algorithm for nfsrv_adj()
since ext_pgs mbuf lists are not permitted to have m_len == 0 mbufs.
As such, the code now frees mbufs after the adjustment in the list instead
of setting their m_len field to 0.
Since mbuf(s) may be trimmed off the tail of the list, the function now
returns a pointer to the last mbuf in the list. This saves the caller
from needing to use m_last() to find the last mbuf.
It also implies that it might return a nul list, which required a check for
that in nfsrvd_readlink().
This is another in the series of commits that add support to the NFS client
and server for building RPC messages in ext_pgs mbufs with anonymous pages.
This is useful so that the entire mbuf list does not need to be
copied before calling sosend() when NFS over TLS is enabled.
Use of ext_pgs mbufs will not be enabled until the kernel RPC is updated
to handle TLS.
