* Join the IPv4 all-hosts multicast group 224.0.0.1 once only;
that is, when an IPv4 address is first configured on an interface.
* Do not join it for subsequent IPv4 addresses as this violates IGMP.
* Be sure to leave the group when all IPv4 addresses have been removed
from the interface.
* Add two DIAGNOSTIC printfs related to the issue.
Further care and attention is needed in this area; it is suggested that
netinet's attachment to the ifnet structure be compartmentalized and
non-implicit.

avoid downcasting issues. In particular, this change fixes
posix_memalign(3) for alignments greater than 2^31 on LP64 systems.
Make sure that NDEBUG is always set to be compatible with MALLOC_DEBUG. [1]

All xxx_<ifname> flags are set to empty strings automatically earlier so
eval echo \${${prefix}${_if}${suffix}-${_default}}
not substitute the default but return just the empty string.
Fix it using
eval echo \${${prefix}${_if}${suffix}:-${_default}}
(i.e. treat empty strings as unset)
The bug manifistates itself with the following warning from checkyesno():
/etc/rc.d/dhclient: WARNING: $background_dhclient is not set properly -
see rc.conf(5)
defined with VFS_LOCK_GIANT(NULL) call.
This shall fix softdep operation when mpsafe_vfs = 0.

GetSeconds(). Instead, use CRTR register shifted right 15. This
gives us a range of 32 seconds we can do for timeout.
Shift to using == rather than < or > for calculating the timeout,
since if we can't read the ST_CTRT register twice in a second we have
even bigger problems to worry about, and == deals with the 'wrap'
issue.
This lets me type at the boot2 prompt again! Woo Hoo!

CSD is usually 512 (well, 9), but for 2GB (and the rogue 4GB SD cards)
it is 1024 (or 2048 for 4GB). This value doesn't work for the block
read commands (which really want 512). Hardcode 512 for those. This
may break really old MMC cards that don't have a 512 block size (I've
never seen one: make my day and send me one :-), but since the MMC
side of the house is currently broken, it should only have the effect
that 2GB (and non-conforming 4GB) SD cards will work.
My 'non-conforming' 4GB SD card also works now too. The
non-conforming 4GB SD cards were sold for a while before the SD
association was worried they would be (a) incompatible (different FAT
flavor on them) and (b) confusing for the new SDHC standard and
cracked down on suppliers' bogus use of the SD trademark...
The changes to getstr() is so that the character that is
passed in to it, is also processed just as the rest. I also
removed one of the getc() calls otherwise you loose every
second character.
I also changed the strcpy of kname, so that it only happens if
kname is '\0'. This is so that one can pass a kernel in
through /boot.config.
The last change to boot2.c is in parse(). If you tried to type
a kernel name to boot, the first character was lost, the arg--
fix that.

trees that track all non-full runs for each bin. Use the red-black
trees to be able to guarantee that each new allocation is placed in the
lowest address available in any non-full run. This change completes the
transition to allocating from low addresses in order to reduce the
retention of sparsely used chunks.
If the run in current use by a bin becomes empty, deallocate the run
rather than retaining it for later use. The previous behavior had the
tendency to spread empty runs across multiple chunks, thus preventing
the release of chunks that were completely unused.
Generalize base_chunk_alloc() (and rename it to base_pages_alloc()) to
handle allocation sizes larger than the chunk size, so that it is
possible to support chunk sizes that are smaller than an arena object.
Reduce the minimum chunk size from 64kB to 8kB.
Optimize tracking of addresses for deleted chunks.
Fix a statistics bug for huge allocations.
that the driver clock is identical to the processor or bus clock.
This is the case for the PowerQUICC processor. When the clock is
high enough, overflows happen in the calculation of the time it
takes to send 1/10 of a character, used in delay loops. Fix the
overflows so as to fix bugs in the delay loops that can cause either
insufficient delays or excessive delays.
