would be read once and cached in a local variable so that the resource limit
check and map entry insertion would be guaranteed to use the same value.
However, the value being passed to vm_map_insert() is still from "sgrowsiz"
and not the local variable. Correct this oversight.

sysarch(2) code.
Use M_ZERO instead of explicit bzero(9). Do not check for failed
allocation when M_WAITOK is specified (which is specified always).
Use malloc(9) when allocating memory for the intermediate copy of the
user-supplied buffer.

VM due to copyin(9) faulting while VFS locks are held is
deadlock-prone there in the same way as for the write(2) syscall.

Patch(1) uses a short int for the line length, which is usually
sufficient for regular diffs, but makes no effort to signal
when there is an overflow.
Change the line length to an unsigned short int to better use
the fact that a length is never negative. The change is loosely
inspired on a related change in DragonFly, but we avoid spending
more memory than necessary.
While here adjust the messages to be clearer on what is happening.

This allows greater granular control over the release
build, and avoids WITH_FOO=1 and WITHOUT_FOO=1 collision.
This change was verified to produce correct results
compared to an earlier build by diffing find(1) output
of the resulting bootonly/, dvd/, and release/ directories.

of invalid characters of the current file instead of an accumulated
value.
- Make do_conv return an error when invalid characters have been found.
Return EXIT_FAILURE from main if any file contained invalid characters.
This matches the behaviour of GNU iconv.
- Mark usage with __dead2 attribute.
- Make the long_options array const.
This change reverts a change from OpenBSD which made use of
calloc, and therefore wasted time initializing arrays that
will later be realloc'ed. Consistently use FreeBSD's
reallocf().
While here also merge the changes from OpenBSD's manpage

This was never intended to be off by default but was done this way
because the initial patches broke the build. Things seem stable now
(have been so for a while too) and "make tinderbox" is clean so let's
try again.
Announced in freebsd-current; all reported shortcomings have been
addressed.
vtfontcvt(8) is now built during buildworld, so can be used as a
bootstrap tool to create vt(4) fonts from source .hex or .bdf font
files, rather than having uuencoded binary fonts in the tree.

avoid congestion on global mountlist_mtx mutex in vfs_busyfs(), while
traversing through the list of mount points.
This change significantly improves NFS server scalability, since it had
to do this translation for every request, and the global lock becomes quite
congested.
This code is more optimized for relatively small number of mount points.
On systems with hundreds of active mount points this simple cache may have
many collisions. But the original traversal code in that case should also
behave much worse, so we are not loosing much.

since it will almost certanly fail. Take next bigger zone instead.
This situation should not happen with original bucket zones configuration:
"32 Bucket" zone uses "64 Bucket" and vice versa. But if "64 Bucket" zone
lock is congested, zone may grow its bucket size and start biting itself.
