- In sched_add(), do the idle check prior to the transfer check so that we
don't try to transfer load from an idle cpu. This fixes panics caused by
IPIs on UP machines running SMP kernels.

to each other.
Correct the recovery thread's loop so that it
will terminate properly on shutdown. We also
clear the recovery_thread proc pointer so that
any additional calls to aic_terminate_recovery_thread()
will not attempt to kill a thread that doesn't
exist. Lastly, code the loop so that termination
will still be successfull even if the termination
request occurs just prior to us entering the loop
or while the recovery thread is off recovering
commands.

The ABI was initially defined for ia64, but GCC3 and Intel compilers
have adopted it on other platforms.
This is the patch from PR bin/59552 with a number of changes by
me.

which means "always stay in the standard mode of PPPoE operation
regardless of any junk floating around."
As the referenced PR stated clearly, the old default setting of 0
was extremely dangerous because it opened a possibility for a
spurious frame not only to put down a single PPPoE node running
FreeBSD, but to plague *every* FreeBSD node in a PPPoE network in
such a way that those nodes would keep poisoning each other until
rebooted simultaneously.

that would cause an infinite loop any time we
manually flush the good status FIFO. Also make
our loop delay unconditional to ensure we don't
miss any FIFO allocations by the hardware.
than a char array. Emitting the data as a big char array works fine in
the typical case, where a .sys file may be ~50K in size. Unfortunately,
some .sys files can be several hundred Kbytes in size, or even several
megabytes in size. One extreme case is the Intel centrino wireless
driver, which is 2.4MB. This causes us to emit an ndis_driver_data.h
file that's on the order of 15MB in size, and gcc consumes enormous
amounts of virtual memory while trying to compile it. On my laptop,
with 128MB of RAM and 256MB of swap space, gcc consumed all available
VM and crashed without being able to compile if_ndis.o.
By emitting the array as assembler, we bypass the C compiler and consume
much less memory. I was able to easily test compile if_ndis.ko with the
centrino driver on my laptop after this change.
This is merely a convenience, and should not have any operational effect
on the NDISulator itself.
nonstandard. They differ in the values of certain fields in
the PPPoE frame. Previously, ng_pppoe would start in standard
mode, yet switch to nonstandard one upon reception of a single
nonstandard frame. After having done so, ng_pppoe would be unable
to interact with standard PPPoE peers. Thus, a DoS condition
existed that could be triggered by a buggy peer or malicious party.
Since few people have expressed their displeasure WRT this problem,
the default operation of ng_pppoe is left untouched for now. However,
a new value for the sysctl net.graph.nonstandard_pppoe is introduced,
-1, which will force ng_pppoe stay in standard mode regardless of any
bogus frames floating around.

1) Fix style issues in comments.
2) Properly namespaceify changes
3) Appropriate sectioning of changes
Not changed: parenthesis around macro rvalue. That would make the additions
inconsistent with the other entries there, merely a different style violation
rather than a clear and obvious improvement so I'm going to have to disagree
with the judges on that one. If someone wishes to adjust *all* the rvalues
to conform to fully parenthesized marco rule, that would be both consistent
and reasonable but that's beyond the scope of the changes I wish to make at
this time.

include adding support for CPU frequency changes.
Add a devd.conf entry for calling this script.
The default values for this are:

performance_throttle_state="HIGH" # 100% (no throttling)
