rt2x00: Preserve descriptor information after memmove()
Due to usage of memmove() in rt2x00usb the descriptor can become
corrupted because it is being overwritten by the data part.
Overall having the descriptor in front of the frame is a bad idea,
we can however use the skb->cb array for this task, since that
contains more then enough room to hold the entire descriptor and
preserve the information long enough.
After this we can also cleanup the alignment code a bit to make it
work a bit more flexible to allow for all kinds of odd header lengths.

rt2x00: Fix queue related oops in case of deselected mac80211 multi-queue feature.
With the integration of the mac80211 multiqueue patches it has become possible that the
mac80211 layer modifies the number of TX queues that is stored inside the ieee80211_hw
structure, especially when multi-queue is not selected.
The rt2x00 drivers are not well suited to handle that situation, as they allocate the
queue structures before mac80211 has modified the number of queues it is going to use,
and also expect the number of allocated queues to match the hardware implementation.
Hence, ensure that rt2x00 maintains by itself the number of queues that the hardware
supports, and, at the same time, making is not dependent on the preservation of contents
inside a mac80211 structure.

rt2x00: Remove ieee80211_tx_control argument from write_tx_desc()
Move the last remaining information details read from ieee80211_tx_control
in the drivers to the txentry_desc structure. After this we can
remove ieee80211_tx_control from the argument list for the callback function,
which makes it easier when the control information is moved into skb->cb

rt2x00: Fix TX status reporting
The tx_status enumeration was broken since the introduction
of rt61pci. That driver uses different values to report the
status of the tx action.
This would lead to frames that were reported as success but
actually failed to be send out, or frames that were neither
successfull or failure which were reported as failure.
Fix this by change the TX status reporting and more explicitely
check for failure or success. Note that a third possibility is
added "unknown". Not all hardware (USB) can report the actual
TX status, for rt61pci some frames will receive this status
because the TXdone handler is never called for those frames.
This unknown will now be handled as neither success or failure,
so we no longer increment the failure counter while this conclusion
could not be determined from the real status of the frame.

rt2x00: trim skb_frame_desc to 32 bytes
Remove frame_type from skb_frame_desc and pass it
as argument to rt2x00debug_dump_frame().
Change data_len and desc_len to unsigned short
to save another 4 bytes in skb_frame_desc. Note that
this was the only location where the data_len and
desc_len was not yet treated as unsigned short.
This trim is required to help mac80211 with adding
the TX control and TX status informtation into the
skb->cb structure. When that happens, drivers will
have approximately 40 bytes left to use freely.

PCI: don't enable ASPM on devices with mixed PCIe/PCI functions
The Slot 03:00.* of JMicron controller has two functions, but one is
PCIE endpoint the other isn't PCIE device, very strange. PCIE spec
defines all functions should have the same config for ASPM, so disable

sparc64: Fix kernel thread stack termination.
Because of the silly way I set up the initial stack for

To fix this, properly add another stack frame that is copied

the frame pointer in that frame to zero.

net: The world is not perfect patch.
Unless there will be any objection here, I suggest consider the
following patch which simply removes the code for the

The compilation errors we get when using -DI_WISH_WORLD_WERE_PERFECT
