- Don't SLOT_USE() in the preempt case, sched_add() has already taken the
slot for us. Previously, we would take two slots on every preempt, and
setrunqueue() would fix it up for us in the non threaded case. The
threaded case was simply broken.
- Clean up flags, prototypes, comments.
Changes to tcp_sack_option() that
- Walks the scoreboard backwards from the tail to reduce the number of
comparisons for each sack option received.
- Introduce functions to add/remove sack scoreboard elements, making
the code more readable.

In newbus land, ivars can only be accessed for direct child, or when
the driver has unholy private knowledge of its great-*cgrandchildren.
The ACPI allocation routine lacked such knowledge when it tried to do
a default allocation for all descendants, rather than just its
immeidate children, so would access grandchild's ivar in an unsafe
way. This could lead to a panic when devices were present which had
no addresses setup by the BIOS, but which were later allocated in a
lazy manner via pci_alloc_map. As such, only do the default
allocation adjustments for immediate children. The manner that
acpi_sysres_find accesses the resource list, used later in
acpi_alloc_resource, is safe and proper so no additional test is
needed there.
This fixes a panic when probing an disabled ata controller on some
newer intel blades.

Mask off the bar's value after the probe test write before testing
against 0 in pci_alloc_map, just like we do in pci_add_map. Also,
make sure that we restore the value to the BAR that was there before
if the bar is 0. Chances are that it was 0 before the write too and
that the restoration is a nop, but better safe than sorry.

New release notes:
FreeBSD/i386 and /amd64 always use the local APIC timer even
on an UP system,
vm.blacklist tunable added,
ipfw now supports IPv4 only rule,
struct netent and getnetbyaddr(3) POSIX conformance and
the ABI breakage on 64-bit platforms, and
GNU GCC 3.4.2-prerelease --> 3.4.4.
Update release notes:
more machine-specific optimized version of math functions.

Remove myself as maintainer of the OSF/1 compat code. I haven't had
an alpha booting -current since my xp1000 died over a year ago, and I
don't think I touched the osf1 code since long before then.
Remove the EXAMPLES section that describes how to sort by size using
sort(1). This functionality is provided by the -S option now, and it
is useful even though a similar effect is achievable with sort(1),
since the latter doesn't work in combination with -h. This option is
also present in NetBSD, OpenBSD, and GNU fileutils, so there's clearly
a demand for it.
Add the -S option to sort files by size. NetBSD and OpenBSD already
have this option with identical semantics (sorting large files first).
-r can be used to reverse the sort if that is desired.

netent.
- Change 1st argument of getnetbyaddr() to an uint32_t on 64 bit
arch as well to confirm to POSIX-2001.
These changes break ABI compatibility on 64 bit arch.
There is similar padding issue for ai_addrlen of struct addrinfo.

Strict locks are only added with core approval and will generally

Fix the load64 and store64 macros, created to handle 8-byte unaligned
loads and stores (resp.) The ldq_u and stq_u instruction mask off the
lower 3 bits of the final address before loading from or storing to

themselves allow loads from or stores to unaligned addresses. Replace
the macro definitions by a packed struct dereference.

Don't enable I/O or memory mode in a device's command register if the BAR
we are processing has a base address of zero. Note that this will only
change behavior for devices where all the BARs of a given type have a base
address of 0 since we will enable the appropriate access when we encounter
the first BAR with a base that is not 0. Specifically, this allows certain
Toshiba laptops to no longer require 'hw.pci.enable_io_modes=0' to avoid
hangs during boot.
