vm_page_xbusy_claim() could clobber the waiter bit. For its original
use, kernel memory pages, this was not a problem since nothing would
ever block on the busy lock for such pages. r363607 introduced a new
use where this could in principle be a problem.
Fix the problem by using atomic_cmpset to update the lock owner. Since
this macro is defined only for INVARIANTS kernels the extra overhead
doesn't seem prohibitive.

- In the initial description of si_addr, do not claim that it is
always the faulting instruction.
- For si_addr, document that it is generally set to the PC for
synchronous signals, but that it can be set to the the address of
the faulting memory reference for some signals including SIGSEGV and
SIGBUS. In particular, while SIGSEGV generally sets si_addr to the
faulting memory reference, SIGBUS can vary. On some platforms, some
SIGBUS signals set si_addr to the PC and other SIGBUS signals set
si_addr to the faulting address depending on the specific hardware
exception.
- For si_trapno, synchronous signals should set this to some value.

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.

QEMU's RISC-V virt machine provides syscon-power and syscon-reset
