Set a proper error message if we hit end-of-file when
trying to read a cpio header.
Suggested by Issue #395, although the actual problem there
seems to have been the same as Issue #394.
Add a check to archive_read_filter_consume to reject any
attempts to move the file pointer by a negative amount.
Note: Either this or commit 3865cf2 provides a fix for
Issue 394.
Issue 394: Segfault when reading malformed old-style cpio archives
Root cause here was an implicit cast that resulted in
reading very large file sizes as negative numbers.
The Windows virtio driver ignores the advertized seg_max
field and assumes the host can accept up to 67 segments
in indirect descriptors, triggering an assert in the bhyve
process.

Netfront has to wait for the backend to switch to state XenbusStateConnected
before sending the ARP request, or else the backend might not be connected
and thus the packet will be lost.

This is one of the few post gcc4.2 builtins that has been implemented by
clang:
__builtin_unreachable is used to indicate that a specific point in the
program cannot be reached, even if the compiler might otherwise think it
can. This is useful to improve optimization and eliminates certain
warnings.

This allows functions that retrieve and inspect pthread_attr_t objects to
work correctly: querying the cpuset_t size is part of querying CPU
affinity information, which is part of creating a complete pthread_attr_t.

The menu entry "Danish ISO-8859-1 (macbook)" was first added to the
syscons(4) INDEX.keymaps in r241851 with no language code, and then in
r256367 incorrectly tagged with "da". It is a Danish keyboard map, but
the description is in English and therefore must be "en".
This error subsequently propagated into the vt(4) INDEX.keymaps.

This extends the existing support for -NORID handles
to include -NICAT, -ARIN, and -RIPE handles.
The suffix machinery is also used to work around a problem with
lack of referrals from the Nominet server for .uk: names under
.ac.uk need to be queried directly at JANET's whois server.
Document the RA_SERVER environment variable.
Remove the obsolete -R option, and discourage people from trying
to use the Network Solutions server.
Describe the default behaviour in the DESCRIPTION section,
not buried in the options.
Present implementation of large sync writes is too strict and so can be
quite slow. Instead of doing that, execute large async write in chunks,
syncing each chunk separately.
It would be good to fix large sync writes too, but I leave it to somebody
with more skills in this area.

GICv3 allows to distribute interrupts to more than 8 cores served by
the previous GIC revisions. GICv3 introduces additional logic in form
of Re-Distributors associated with particular CPUs to determine
the highest priority interrupts and manage PPIs and LPIs
(Locality-specific Peripheral Interrupts). Interrupts routing is
based on CPUs' affinity numbers. CPU interface was changed to be
accessible via CPU System Registers and this is the preferred
(and supported) method in this driver.

When examining existing processes pmcstat fails to
correctly determine the locations of executable sections
of the process due to a miscalculated virtual load address.
This does not affect the newly launched processes as the
same value passed as a "start address" to the pmcstat_image_link()
thus nullifying the effect of it. The issue manifests itself
in processes not being reported in the pmcstat(8) output and
"dubious frames" being reported.
Fix it for now by ignoring all the sections except the executable
one. This won't fix the issue for objects with multiple
executable sections but helps in majority of real world usecases.
The real solution would be to modify the MAP-IN event to include
the appropriate load address so pmcstat(8) won't have to manually
parse object files to try to determine it.

The consumers of hw.intrnames expect a NULL byte at end of the string
containing the interrupt names.
On ARM all the interrupt name slots are initialized and this leave no room
for the terminating NULL byte, which makes vmstat read beyond the end of
intrnames.
