syscall. It was broken when a new lseek syscall was introduced.
The problem is that we need to swap the 32-bit td_retval values
for the __syscall indirect syscall when the actual syscall has
a 32-bit return value. Hence, we need to exclude lseek(2). And
this means the "old" lseek(2) as well -- which we didn't.

errors (especially when jumbo frames are enabled or in low memory systems)
because the RX chain was corrupted when an mbuf was mapped to an unexpected
number of buffers.
- Fixed a problem that would cause kernel panics when an excessively
fragmented TX mbuf couldn't be defragmented and was released by
bce_tx_encap().

bucket pointer. The virtual mapping may not be present in the
translation cache. This will result in a nested TLB fault at
a place we don't handle (and don't want to handle).
o Make sure there's a stop after the rfi instruction, otherwise
its behaviour is undefined.
o Make sure we switch back to virtual addressing before doing
a rfi. Behaviour is undefined otherwise.

(INTR_FILTER). This includes:
o Save a pointer to the sapic structure and IRQ for every vector,
so that we can quickly EOI, mask and unmask the interrupt.
o Add locking to the sapic code now that we can reprogram a
sapic on multiple CPUs at the same time.
o Use u_int for the vector and IRQ. We only have 256 vectors, so
using a 64-bit type for it is rather excessive.
o Properly handle concurrent registration of a handler for the
same vector.
Since vectors have a corresponding priority, we should not map
IRQs to vectors in a linear fashion, but rather pick a vector
that has a priority in line with the interrupt type. This is left
for later. The vector/IRQ interchange has been untangled as much
as possible to make this easier.

merely lucky that the VHPT was mapped as a side-effect of
mapping the kernel, but when there's enough physical memory,
this may not at all be the case.

- Use the MTU from the first interface as the lagg MTU, all extra interfaces
must be the same.
This fixes using a lagg interface for a vlan or enabling jumbo frames, etc.

the fast or safe/slow method is in use. Fast remains at 1000, slow is
now at 850 (always preferred to TSC). Since the HPET has proven slower
than ACPI-fast on some systems, drop its quality to 900. In the future,
it is hoped that HPET performance will improve as it is the main
timer Intel supports. HPET may move back to 2000 in -current once RELENG_7
is branched to ensure that it gets tested.

containing 64-bit arguments would have explicit padding.
On 64-bit platforms there was no padding, so the dummy
argument was not covering anything. On 32-bit platforms
with weak alignment (i.e. i386) the 64-bit argument did
not need to be aligned, so there too an aditional argument
was introduced. On 32-bit platforms with strong alignment
(i.e. PowerPC) the dummy argument in fact cover the padding.
By elimininating the dummy argument, 64-bit platforms now
have 1 argument less. This also applies to 32-bit platforms
with weak alignment. On PowerPC this doesn't matter, because
the padding is still there. We just don't "name" it.
Deal with those 3 cases.

sys.net.inet.tcp.log_debug = 1
It defaults to enabled for the moment and is to be turned off for
the next release like other diagnostics from development branches.
It is important to note that sysctl sys.net.inet.tcp.log_in_vain
uses the same logging function as log_debug. Enabling of the former
also causes the latter to engage, but not vice versa.
Use consistent terminology in tcp log messages:
"ignored" means a segment contains invalid flags/information and
is dropped without changing state or issuing a reply.
"rejected" means a segments contains invalid flags/information but
is causing a reply (usually RST) and may cause a state change.

o Reset timeout when duplicate SYN arrives.

a proper solution.
- Add a dummy entry point which just calls the C entry points, and try to make
sure it's the first code in the binary.
- Copy a bit more than func_end to try to copy the whole load_kernel()
function. gcc4 puts code behind the func_end symbol.
