machines. Specifically, there was a mismatch between how the routine
allocation and deallocation operations accessed the population map
and how the aggressively optimized reservation-breaking operation
accessed it. So, problems only occurred when reservations were broken.
This change makes the routine operations access the population map in
the same way as the reservation breaking operation.
This bug was introduced in r259999.

In particular, don't check the value of the bus_dma map against NULL
to determine if either bus_dmamem_alloc() or bus_dmamap_load() succeeded.
Instead, assume that bus_dmamap_load() succeeeded (and thus that
bus_dmamap_unload() should be called) if the bus address for a resource
is non-zero, and assume that bus_dmamem_alloc() succeeded (and thus
that bus_dmamem_free() should be called) if the virtual address for a
resource is not NULL.
In many cases these bugs could result in leaks when a driver was detached.

Direct bpf(4) consumers should now work fine with this tunable turned on.
In fact, the only case when optimized_writers can change program
behavior is direct bpf(4) consumer setting its read filter to

This partitioning scheme is used in DragonFlyBSD. It is similar to
BSD disklabel, but has the following improvements:
* metadata has own dedicated place and isn't accessible through partitions;
* all offsets are 64-bit;
* supports 16 partitions by default (has reserved place for more);
* has reserved place for backup label (but not yet implemented);
* has UUIDs for partitions and partition types;

don't create a map before calling bus_dmamem_alloc() (such maps were
leaked). It is believed that the extra destroy of the map was generally
harmless since bus_dmamem_alloc() often uses special maps for which
bus_dmamap_destroy() is a no-op (e.g. on x86).

vtfontcvt is useful for end users to convert arbitrary bitmap fonts
for use by vt(4). It can also be used as a build tool, allowing us
to keep the source font data in the src tree rather than uuencoded
binaries.

Force all the contents of /usr/tests to go into a separate distribution
file so that users of binary releases can easily choose to not install it.
To make this possible, we need two fixes:
- bsd.subdir.mk needs to properly honor NO_SUBDIR in all cases so that we
do not recurse into 'tests' subdirectories when we needn't. Otherwise,
we end up with some Kyuafiles in base.txz.
- etc/Makefile needs to skip installing tests in its 'distribute' target
so that a Kyuafile doesn't leak into base.txz.

injected into the guest. This allows the hypervisor to inject another
ExtINT or APIC vector as soon as the guest is able to process interrupts.
This change is not to address any correctness issue but to guarantee that
any pending APIC vector that was preempted by the ExtINT will be injected
as soon as possible. Prior to this change such pending interrupts could be
delayed until the next VM exit.
Per POSIX, siglongjmp() shall be equivalent to longjmp() except that it must
match sigsetjmp() instead of setjmp() and except for the effect on the
signal mask. Therefore, it should preserve the floating point exception
flags.
This was fixed for longjmp() and _longjmp() in r180080 and r180081 for amd64
and i386 respectively.
Perform an O(n) deduplication pass over the bold maps at the end, rather

a bold mapping entry is added.
