made some trivial changes but was missing a ';' character.
8c4cc00552 "ARM: OMAP1: DMA: Moving OMAP1 DMA channel definitions
to mach-omap1" added a definition for OMAP_DMA_USB_W2FC_TX0 to
the driver while making the header file it was defined in
unavailable for drivers, but this driver actually needs
OMAP_DMA_USB_W2FC_RX0 as well.
Both changes appear trivial, so let's add the missing semicolon
and the macro definition.
This reverts commit 200e0d99 ("USB: storage: optimize to match the
Huawei USB storage devices and support new switch command" and the
followup bugfix commit cd060956 ("USB: storage: properly handle
the endian issues of idProduct").
The commit effectively added a large number of Huawei devices to
the deprecated usb-storage mode switching logic. Many of these
devices have been in use and supported by the userspace
usb_modeswitch utility for years. Forcing the switching inside
the kernel causes a number of regressions as a result of ignoring
existing onfigurations, and also completely takes away the ability
to configure mode switching per device/system/user.
Known regressions caused by this:
- Some of the devices support multiple modes, using different
switching commands. There are existing configurations taking
advantage of this.
- There is a real use case for disabling mode switching and
instead mounting the exposed storage device. This becomes
impossible with switching logic inside the usb-storage driver.
- At least on device fail as a result of the usb-storage switching
command, becoming completely unswitchable. This is possibly a
firmware bug, but still a regression because the device work as
expected using usb_modeswitch defaults.
In-kernel mode switching was deprecated years ago with the
development of the more user friendly userspace alternatives. The
existing list of devices in usb-storage was only kept to prevent
breaking already working systems. The long term plan is to remove
the list, not to add to it. Ref:

Commit 80ab72e1 (usb: musb: omap2430: fix the readiness check

glue/link status during the normal built-in probe order (twl4030_usb is
probed after musb omap2430, but before musb core is ready).
As a result, if you boot with USB cable on and load g_ether, the
connection does not work as the code thinks the cable is off and the
phy gets powered down immediately. This is a major regression in 3.9-rc1.
So the proper check should be: exit if _glue is NULL, but if it's

USB: EHCI: don't check DMA values in QH overlays
This patch (as1661) fixes a rather obscure bug in ehci-hcd. In a
couple of places, the driver compares the DMA address stored in a QH's
overlay region with the address of a particular qTD, in order to see
whether that qTD is the one currently being processed by the hardware.
(If it is then the status in the QH's overlay region is more
up-to-date than the status in the qTD, and if it isn't then the
overlay's value needs to be adjusted when the QH is added back to the
active schedule.)
However, DMA address in the overlay region isn't always valid. It
sometimes will contain a stale value, which may happen by coincidence
to be equal to a qTD's DMA address. Instead of checking the DMA
address, we should check whether the overlay region is active and
valid. The patch tests the ACTIVE bit in the overlay, and clears this
bit when the overlay becomes invalid (which happens when the
currently-executing URB is unlinked).

USB: EHCI: work around silicon bug in Intel's EHCI controllers
This patch (as1660) works around a hardware problem present in some
(if not all) Intel EHCI controllers. After a QH has been unlinked
from the async schedule and the corresponding IAA interrupt has
occurred, the controller is not supposed access the QH and its qTDs.
There certainly shouldn't be any more DMA writes to those structures.
Nevertheless, Intel's controllers have been observed to perform a
final writeback to the QH's overlay region and to the most recent qTD.
For more information and a test program to determine whether this
problem is present in a particular controller, see
This patch works around the problem by always waiting for two IAA
cycles when unlinking an async QH. The extra IAA delay gives the
controller time to perform its final writeback.
Surprisingly enough, the effects of this silicon bug have gone
undetected until quite recently. More through luck than anything
else, it hasn't caused any apparent problems. However, it does
interact badly with the path that follows this one, so it needs to be
addressed.

raid56 code that David Woodhouse started long ago. I'm still working
on the parity logging setup that will avoid inconsistent parity after

to get it out to a broader audience to hammer out any performance
issues or other problems.
scrub does not yet correct errors on raid5/6 either.
Josef has another pass at fsync performance. The big change here is
to combine waiting for metadata with waiting for data, which is a big
latency win. It is also step one toward using atomics from the
hardware during a commit.
Mark Fasheh has a new way to use btrfs send/receive to send only the
metadata changes. SUSE is using this to make snapper more efficient
at finding changes between snapshosts.
Snapshot-aware defrag is also included.
Otherwise we have a large number of fixes and cleanups. Eric Sandeen

ext4_mark_dquot_dirty() forgets to test for quota feature so it was

However <linux/preempt.h> cannot be easily included from

!SMP case, and potentially in the SMP case in the future. Therefore move
the SMP implementation of arch_local_irq_enable() into traps.c and use
an inline version of get_trigger_mask() which is also defined in traps.c
for SMP.
This adds an extra layer of function call / stack push when
preempt_disable needs to call other functions, however in the
non-preemptive SMP case it should be about as fast, as it was already
calling the get_trigger_mask() function which is now used inline.
