OHCI: final fix for NVIDIA problems (I hope)
Problems with NVIDIA's OHCI host controllers persist. After looking
carefully through the spec, I finally realized that when a controller
is reset it then automatically goes into a SUSPEND state in which it
is completely quiescent (no DMA and no IRQs) and from which it will
not awaken until the system puts it into the OPERATIONAL state.
Therefore there's no need to worry about controllers being in the
RESET state for extended periods, or remaining in the OPERATIONAL
state during system shutdown. The proper action for device
initialization is to put the controller into the RESET state (if it's
not there already) and then to issue a software reset. Similarly, the
proper action for device shutdown is simply to do a software reset.
This patch (as1499) implements such an approach. It simplifies
initialization and shutdown, and allows the NVIDIA shutdown-quirk code
to be removed.

usb-storage: Accept 8020i-protocol commands longer than 12 bytes
The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands;
shorter commands must be padded. Simon Detheridge reports that his
3-TB USB disk drive claims to use the 8020i protocol (which is
normally meant for ATAPI devices like CD drives), and because of its
large size, the disk drive requires the use of 16-byte commands.
However the usb_stor_pad12_command() routine in usb-storage always
sets the command length to 12, making the drive impossible to use.
Since the SFF-8020i specification allows for 16-byte commands in
future extensions, we may as well accept them. This patch (as1490)
changes usb_stor_pad12_command() to leave commands larger than 12
bytes alone rather than truncating them.

USB: EHCI: fix HUB TT scheduling issue with iso transfer
The current TT scheduling doesn't allow to play and then record on a
full-speed device connected to a high speed hub.
The IN iso stream can only start on the first uframe (0-2 for a 165 us)
because of CSPLIT transactions.
For the OUT iso stream there no such restriction. uframe 0-5 are possible.
The idea of this patch is that the first uframe are precious (for IN TT iso
stream) and we should allocate the last uframes first if possible.
For that we reverse the order of uframe allocation (last uframe first).
Here an example :
hid interrupt stream
----------------------------------------------------------------------
uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
----------------------------------------------------------------------
max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 |
----------------------------------------------------------------------
used usecs on a frame | 13 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
----------------------------------------------------------------------
iso OUT stream
----------------------------------------------------------------------
uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
----------------------------------------------------------------------
max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 |
----------------------------------------------------------------------
used usecs on a frame | 13 | 125 | 39 | 0 | 0 | 0 | 0 | 0 |
----------------------------------------------------------------------
There no place for iso IN stream (uframe 0-2 are used) and we got "cannot
submit datapipe for urb 0, error -28: not enough bandwidth" error.
With the patch this become.
iso OUT stream
----------------------------------------------------------------------
uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
----------------------------------------------------------------------
max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 |

USB: XHCI: resume root hubs when the controller resumes
This patch (as1494) fixes a problem in xhci-hcd's resume routine.
When the controller is runtime-resumed, this can only mean that one of
the two root hubs has made a wakeup request and therefore needs to be
resumed as well. Rather than try to determine which root hub requires
attention (which might be difficult in the case where a new
non-SuperSpeed device has been plugged in), the patch simply resumes
both root hubs.
Without this change, there is a race: The controller might be put back
to sleep before it can activate its IRQ line, and the wakeup condition
might never get handled.
The patch also simplifies the logic in xhci_resume a little, combining
some repeated flag settings into a single pair of statements.

USB: ci13xxx_udc: fix logic to mark request dma addresses as invalid
The current driver sets the request's dma addr (mReq->req.dma) to 0 to
mark the DMA address as not valid. However some gadget drivers
(e.g. gadgetfs) set the request's dma addr to DMA_ADDR_INVALID to mark
the address as invalid. This leads to bogus data send because the
ci13xxx_udc driver assumes the request has already been mapped.
This patch fixes the problem, by using DMA_ADDR_INVALID instead of 0
to mark the request's DMA address as invalid.

USB: gadgetfs: gadgetfs_disconnect: fix inconsistent lock state
Under certain circumstances lockdep finds an inconsistent lock state in
gadgetfs. The problem can be reproduced with a hardware using the
ci13xxx_udc driver and the gadgetfs test program (needs a patch to support
the ci13xxx_udc, though):
http://www.linux-usb.org/gadget/usb.c
Start the test program, wait to initialize, then press Ctrl+c.
This patch fixes the following problem by using spin_lock_irqsave()
instead of spin_lock().

Also, genius Windows 7(tm) terminates it's life cycle instantly with a

VFS: we need to set LOOKUP_JUMPED on mountpoint crossing
Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

forcedeth: Improve stats counters
Rx byte count was off; instead use the hardware's count. Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.
- The count of transmitted packets reported by the forcedeth driver
reports pre-TSO (TCP Segmentation Offload) packet counts and not the
count of the number of packets sent on the wire. This change fixes
the forcedeth driver to report the correct count. Fixed the code by
copying the count stored in the NIC H/W to the value reported by the
driver.
- Count rx_drop_frame errors as rx_fifo_errors:
We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
for too long. Normally, rx_fifo_errors would be counted in this case.
The rx_drop_frame error count is private to forcedeth and is not
reported by ifconfig or sysfs. The rx_fifo_errors count is currently
unused in the forcedeth driver. It is reported by ifconfig as overruns.
This change reports rx_drop_frame errors as rx_fifo_errors.

hid/apple: modern macbook airs use the standard apple function key translations
This removes the use of the special "macbookair_fn_keys" keyboard
translation table for the MacBookAir4,x models (ie the 2011 refresh).
They use the standard apple_fn_keys[] translation. Apparently only the
old MacBook Air's need a different translation table.
This mirrors the change that commit
da617c7cb915 ("HID: consolidate
MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for
the WELLSPRING6 model used on the MacBookAir4,2.
