The prefix management code currently resides in nd6, leaving only the
unused router renumbering capability in the in6_prefix files. Removing
it will make it easier for us to provide locking for the remainder of
IPv6 by reducing the number of objects requiring synchronized access.
This functionality has also been removed from NetBSD and OpenBSD.

deal with 24-bit addresses. While the two other attachments, namely
isa and cbus, do it properly, the PCI attachment was passing
BUS_SPACE_MAXADDR instead of BUS_SPACE_MAXADDR_24BIT. This bug
became apparent with the new contigmalloc() code.
This fixes the problem reported with lnc(4) interfaces inside VMWare,
and should theoritically also fix any user of a PCI lnc(4) card. It
is a RELENG_5 MFC candidate.

position that is 64-bit aligned and makes sure that the valid and
dirty fields are also 64-bit aligned. This means that if PAGE_SIZE
is 32K, the size of the vm_page structure is only increased by 8
bytes instead of 16 bytes. More importantly, the vm_page structure
is either 120 or 128 bytes on ia64. These are "interesting" sizes.
before returning. Device nodes are created via the "taste" mechanism,
so this is necessary in order to make sure that devfs entries are
created before mdconfig(8) returns.
This may be a MFC candidate for 5.3.

allocation. Notably, in this case, the driver tries to allocate several
pieces of memory and then fails if the pieces allocated after the first
do not come after it physically, and within a specific range (8MB I
believe). Of course, this could just as easily fail for any number of
reasons, but it almost always fails now that contiguous allocations start
at the end of possible specified memory locations rather than the beginning.
Allocate all the possibly-needed memory up front, even though it's a waste,
to get around this. The least bogus solution would be to take the physical
address from the first allocation and create a new tag that specified that
further allocations must follow it within that 8MB window, then use that
when allocating new channels, but that's left for anyone else that really
feels like doing it.

Previously the early drop was disabled unconditionally for ALTQ-enabled
kernels.
This should give some benefit for the normal gateway + LAN-server case with
a busy LAN leg and an ALTQ managed uplink.

The whole problem seems to be size. Which is odd, because it is said
that size doesn't matter. Anyway... Add -Os to strategic places in the
makefile to have the final loader be as mall as possible. This seems
to be enough to make it work. For now... I think something is more
fundamentally wrong; or something more fundamental is wrong. Potato,
potaato.
this script, without it sparc64 ISO building was consistently failing
because the /dev/md0 device name was not present when the commands
following mdconfig ran. Apparently there is the possibility of a delay
between when mdconfig finishes and the names become visible in /dev.
Yes, we could code this better than an unconditional call to "sleep 5"
but IMHO we should fix the underlying problem instead.

be manipulated by prison root. In 4.x prison root can not manipulate
system flags, regardless of the security level. This behavior
should remain consistent to avoid any surprises which could lead
to security problems for system administrators which give out
privileged access to jails.
This commit changes suser_cred's flag argument from SUSER_ALLOWJAIL
to 0. This will prevent prison root from being able to manipulate
system flags on files.
This may be a MFC candidate for RELENG_5.

The binutils 2.15 assembler now automaticly and non-optionally adds
the .eh_frame section for unwind information. This section appears
to wreck havoc to the final boot code. Fix this by using a special
linker script that discards the .eh_frame sections, but is otherwise
identical to the linker internal script used for -N.
