868719752d Revert "USB: xhci: Use GFP_ATOMIC under spin_lock"
This reverts commit ef821ae70f.

The correct thing to do is to drop the spinlock, not change
the GFP flag here.

Thanks to Sarah for pointing out I shouldn't have taken this patch in
the first place.

28609d4083 usb: subtle increased memory usage in u_serial
OK, the USB gadget serial driver actually has a couple of problems.  On
gs_open(), it always allocates and queues an additional QUEUE_SIZE (16)
worth of requests, so with a loop like this:

    i=1 ; while echo $i > /dev/ttyGS0 ; do let i++ ; done

eventually we run into OOM (Out of Memory).

Technically, it is not a leak as everything gets freed up when the USB
connection is broken, but not on gs_close().

With a USB device/gadget controller driver that has limited resources
(e.g., Marvell has a this MAX_XDS_FOR_TR_CALLS of 64 for transmit and
receive), so even after 4

    stty -F /dev/ttyGS0

we cannot transmit anymore.  We can still receive (not necessarily
reliably) as now we have 16 * 4 = 64 descriptors/buffers ready, but the
device is otherwise not usable.

58c0d9d701 USB: option: fix when the driver is loaded incorrectly for some Huawei devices.
When huawei datacard with PID 0x14AC is insterted into Linux system, the
present kernel will load the "option" driver to all the interfaces. But
actually, some interfaces run as other function and do not need "option"
driver.

In this path, we modify the id_tables, when the PID is 0x14ac ,VID is
0x12d1, Only when the interface's Class is 0xff,Subclass is 0xff, Pro is
0xff, it does need "option" driver.

018b97d084 USB: Fix FSL USB driver on non Open Firmware systems
Commit 126512e3f2 added support for FSL's USB
controller on powerpc. In this commit the Open Firmware code was selected
and compiled unconditionally.

This breaks on ARM systems from FSL which use the same driver (.i.e. the i.MX
series), because ARM don't have OF support (yet). This patch fixes the problem
by only selecting the OF code on systems with Open Firmware support.

02e031cbc8 block: remove REQ_HARDBARRIER
REQ_HARDBARRIER is dead now, so remove the leftovers.  What's left
at this point is:

 - various checks inside the block layer.
 - sanity checks in bio based drivers.
 - now unused bio_empty_barrier helper.
 - Xen blockfront use of BLKIF_OP_WRITE_BARRIER - it's dead for a while,
   but Xen really needs to sort out it's barrier situaton.
 - setting of ordered tags in uas - dead code copied from old scsi
   drivers.
 - scsi different retry for barriers - it's dead and should have been
   removed when flushes were converted to FS requests.
 - blktrace handling of barriers - removed.  Someone who knows blktrace
   better should add support for REQ_FLUSH and REQ_FUA, though.

6e16edfe62 usb: musb: fail unaligned DMA transfers on v1.8 and above
The Inventra DMA engine in version 1.8 and later of the MUSB
controller cannot handle DMA addresses that are not aligned
to a 4 byte boundary. It ends up ignoring the last two bits
programmed in the DMA_ADDR register. This is a deliberate
design change in the controller and is documented in the
programming guide.

Earlier versions of the controller could handle these
accesses just fine.

Fail dma_channel_program if we see an unaligned address when
using the newer controllers, so that the caller can carry out
the transfer using PIO mode.
(Current callers already have this backup path in place).

musb driver still may write MUSB_DEVCTL register after clock is disabled

31c9909b51 USB: musb: gadget: fix MUSB_TXMAXP and MUSB_RXMAXP configuration
Commit 9f445cb29918dc488b7a9a92ef018599cce33df7[USB: musb: disable
double buffering for older RTL versions] tries to disable double
buffer mode by writing endpoint hw max packet size to TXMAP/RXMAP.

First the approach can break full speed and cause overflow problems.
We should always set those registers with the actual max packet size
from endpoint descriptor.

Second, the problem describe by commit 9f445cb299
was caused by musb gadget driver; nothing to do with RTL revision as
originaly suspected.

The real fix to the problem is to always use actual max packet
size from endpoint descriptor to config TXMAP/RXMAP registers.

120d074c58 usb: musb: don't leave PHY enabled on shutdown()
Some actions like musb_platform_exit are only performed on module
removal and not on shutdown, which results in PHY being left enabled
on reboot at least. This is sometimes causing strange failures after
reboot (observed on OMAP3 pandora board), when DEVCTL does not report
VBUS state correctly due to unknown reasons (possibly because of
communication issues between musb IP and PHY). Running
musb_platform_exit before reset seems to resolve that issue.

Move some exit code from musb_remove() to musb_shutdown() so that it
is performed on both module removal and shutdown/reset. Also convert
the host check so that it doesn't need #ifdef.

9001d80df9 usb: musb: gadget: fix dma mode 0 in double buffer Rx case
1, In Rx double buffer case, FIFO may have two packets, so
rxstate should be called to unload fifo if RXPKTRDY is set
even the current request has not been completed.

2, Commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85
introduces autoclear to support double buffer in dma mode 0,
so remove clearing RXPKTRDY manually for dma mode 0.

3, Commit c7af6b29ffeffbeb28caf39e5b2ce29b11807c7d may break
dma mode 1 for non-doublebuffer endpoint, fix it.

With this patch, either usbtest #5 or g_file_storage(writing
file to device in usb host) or g_ether have been tested OK in
double buffer case(using fifo mode 3). Also, this patch has
been verified that single buffer case can't be broken.

1643accdaa USB: Add EHCI and OHCH glue for OCTEON II SOCs.
The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus.  This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.

The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.

The ehci and ohci blocks share a common clocking and PHY
infrastructure.  Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.

Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in
arch/mips/Kconfig in a following patch.

85fe4025c6 fs: do not assign default i_ino in new_inode
Instead of always assigning an increasing inode number in new_inode
move the call to assign it into those callers that actually need it.
For now callers that need it is estimated conservatively, that is
the call is added to all filesystems that do not assign an i_ino
by themselves.  For a few more filesystems we can avoid assigning
any inode number given that they aren't user visible, and for others
it could be done lazily when an inode number is actually needed,
but that's left for later patches.

92ca0dc5ee USB: mct_u232: fix broken close
Fix regression introduced by commit
f26788da3b (USB: serial: refactor generic
close) which broke driver close().

This driver uses non-standard semantics for the read urb which makes the
generic close function fail to kill it (the read urb is actually an
interrupt urb and therefore bulk_in size is zero).
