a6ca48085c The POSIX spec also requires that kern_sigtimedwait return 
EINVAL if tv_nsec of the timeout is less than zero.

ca4125f7b3 Create a subtree 'harp' of the net sysctl tree. This uses a fixed 
OID as the other protocol family sub-trees do, that is equal to the
protocol family identifier. Make the ATM layer debugging flags
available under this tree.

2a51529f7e Provide a knob for raising the inline instruction estimate threshold and 
set an initial value.  This is aimed at getting us closer to being able to
turn -Werror back on and we can adjust the settings later on.  Yes, we
could turn off -Wno-inline instead, but that would hide the effect of
gcc's bogo-estimator ignoring inline (either rightly or wrongly).

3462150083 Annotate pmap_changebit() as __always_inline. This function was 
written as a template that when inlined is specialized for the caller
through constant value propagation and dead code elimination.  Thus,
the specialized code that is generated for pmap_clear_reference() et
al. avoids several conditional branches inside of a loop.

793e17ba11 We sloppily created an array for the high FP registers (f32-f127), 
but this just created a weird inconsistency when porting gdb(1).
Instead, we name each high FP register seperately, like we do for
all the other registers.

a33f5caff3 Attempt to preempt any new gcc-ism references to 
__attribute__((__always_inline__)) by adding an __always_inline macro
(used like __dead2 etc).  __inline_damnit has also been suggested but we
have a precedent of keeping the names similar so they are easier to find.

05ab0ba3b5 Allocate network interfaces from malloc() instead of using a zone. 
Usually one needs only a couple of them so using a zone is waste
of memory (esp. on multi-cpu systems).

b92ba02261 Remove the zone limits for all the zones used in the ATM code. 
These were a left over from when the private memory pools were
converted to use uma zones. The limit of UMA zones, however,
works differently. When a zone is limited to only one or two pages
than, on multi-cpu systems, processes can get stuck on the zonelimit,
because all remaining free items are in caches of other CPUs.

Also add rudimentary error handling in some places (panic) when a zone
cannot be created.
