is not complete because some ohci controlers are not initialized completely.
So "kernel: usb0: 1 scheduling overruns" interrupt will generate many times.
This change will be same one in PR kern/60099.

In NdisQueryBuffer() and NdisQueryBufferSafe(), the vaddr argument is
optional, so test it before trying to dereference it.
Also correct NdisGetFirstBufferFromPacket()/NdisGetFirstBufferFromPacketSafe():
we need to use nb_mappedsystemva from the buffer, not nb_systemva.
routines: NdisUnchainBufferAtBack(), NdisGetFirstBufferFromPacketSafe()
and NdisGetFirstBufferFromPacket(). This should bring us a little
closer to getting the Intel centrino wireless NIC to work.
Note: I have not actually tested these additions since I don't
have a driver that calls them, however they're pretty simple, and
one of them is taken pretty much directly from the Windows ndis.h
header file, so I'm fairly confident they work, but disclaimers
apply.
This guard page would have trapped the problems with the MFC of the PAE

pmap_init(). Such a large preallocation is unnecessary and wastes
nearly eight megabytes of kernel virtual address space per gigabyte
of managed physical memory.
- Increase UMA_BOOT_PAGES by two. This enables the removal of
pmap_pv_allocf(). (Note: this function was only used during
initialization, specifically, after pmap_init() but before
pmap_init2(). During pmap_init2(), a new allocator is installed.)

parse() is used to allow future options to be processed.
mincore(2) should check that the page is valid, not just allocated.
Otherwise, it can return a false positive for a page that is not yet
resident because it is being read from disk.
- Make ndis_get_info()/ndis_set_info() sleep on the setdone/getdone
routines if they get back NDIS_STATUS_PENDING.
- Add a bunch of net80211 support so that 802.11 cards can be twiddled
with ifconfig. This still needs more work and is not guaranteed to
work for everyone. It works on my 802.11b/g card anyway.
The problem here is Microsoft doesn't provide a good way to a) learn
all the rates that a card supports (if it has more than 8, you're
kinda hosed) and b) doesn't provide a good way to distinguish between
802.11b, 802.11b/g an 802.11a/b/g cards, so you sort of have to guess.
Setting the SSID and switching between infrastructure/adhoc modes
should work. WEP still needs to be implemented. I can't find any API
for getting/setting the channel other than the registry/sysctl keys.
cpu could have been bogged down with non-transferable load and still not
migrated a new thread to an idle cpu. This required some benchmarking and
tuning to get right as the comment above it suggests.
otherwise they are initialized twice when the code is statically
configured in the kernel because the module load method gets
invoked before the user application calls ip_mrouter_init
o add a mutex to synchronize the module init/done operations; this
sort of was done using the value of ip_mroute but X_ip_mrouter_done
sets it to NULL very early on which can lead to a race against
ip_mrouter_init--using the additional mutex means this is safe now
o don't call ip_mrouter_reset from ip_mrouter_init; this now happens
once at module load and X_ip_mrouter_done does the appropriate
cleanup work to insure the data structures are in a consistent
state so that a subsequent init operation inherits good state

Correct the recovery thread's loop so that it

clear the recovery_thread proc pointer so that
any additional calls to aic_terminate_recovery_thread()

As the referenced PR stated clearly, the old default setting of 0

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.

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.
