OK. Then, I think we also want to fix these warnings probably introduced by
commit a6021559 "UBUNTU: SAUCE: (no-up) Modularize vesafb".
WARNING: drivers/video/vesafb.o(.exit.text+0x42): Section mismatch in reference from the function vesafb_remove() to the (unknown reference) .init.data:(unknown)
The function __exit vesafb_remove() references
a (unknown reference) __initdata (unknown).
This is often seen when error handling in the exit function
uses functionality in the init path.
The fix is often to remove the __initdata annotation of
(unknown) so it may be used outside an init section.

it is unsupported
Submitted upstream.
BugLink: http://bugs.launchpad.net/bugs/962038
Right now using pcie_aspm=force will not enable ASPM if the FADT indicates
ASPM is unsupported. However, the semantics of force should probably allow
for this, especially as they did before the ASPM disable rework with commit
3c076351c4027a56d5005a39a0b518a4ba393ce2
This patch just skips the clearing of any ASPM setup that the firmware has
carried out on this bus if pcie_aspm=force is being used.

Introduce a new VT mode KD_TRANSPARENT which endevours to leave the current
content of the framebuffer untouched. This allows the bootloader to insert
a graphical splash and have the kernel maintain it until the OS splash
can take over. When we finally switch away (either through programs like
plymouth or manually) the content is lost and the VT reverts to text mode.

When a drm driver is initialised we first allocate and initialise the
drm minor numbers including creating the sysfs files, then we trigger
the driver load method. The act of creating the sysfs files triggers the
uevent. This means udev may start programs which open /dev/dri/card0 and
other interfaces, this can occur before the load method has even started
and thus before the driver has fully initialised its data structures.
In the case of plymouthd this leads to it opening and closing (in disgust)
the interface, which in turn leads to a kernel panic as the mutexes are
yet to be initialised.
This patch delays the linking up of the drm devices minor numbers until
the driver is fully initialised. As it is possible for consumers of
these interfaces to reach them before they are fully initialised we
arrange for opens of these devices to return EAGAIN until the device is
fully initialised.

BugLink: http://bugs.launchpad.net/bugs/397734
It seems that users are have a high expectation that the eject button
on their CDROM drive will eject the disk regardless of whether it is in
use or not. To this end we are now changing the default LOCK mode for
mounted CDROMS to 0 to allow ejects. This however does not handle the
direct open cases like music and video players. From the launchpad bug
commentary:
So, according to the upstream discussion David Zeuthen recommended
to just not lock CD-ROM trays by default. Kernel/userspace already
handles prematurely removed USB storage devices reasonably, and with
read-only devices like CD-ROMs it is even less of an issue. So we
should just set /proc/sys/dev/cdrom/lock to 0 by default.
Note that we still will have the drive mounted after the eject. There is a
media change uevent generated and this will be used to trigger the unmount
of the drive in udisks. The burner software will also have to be looked
at to ensure they are explicitly locking the drive closed during the burn.
This will all be handled under the bug above.

With the introduction of wireless USB hubs the product, manufacturer,
and serial number are now mutable. This necessitates new locking in the
consumers of these values including the sysfs read routines in order to
prevent use-after-free acces to these values. These extra locks create
significant lock contention leading to increased boot times (0.3s for an
example Atom based system). Move update of these values to RCU based
locking.

When instantiating the battery object on to the acpi bus in the kernel
we talk to the BIOS to get the current battery state. This can take
a long time and holds the acpi bus object locked for the duration.
This leads to any other object wishing to add itself that bus blocking.
This leads to unpredicatable delays of up to .3s when initialising the
hpet during boot depending on execution order. Make the first update of
the battery asynchronous. Move the acpi bus handling back synchronous.

acpi_video_bus_start_devices() in drivers/acpi/video.c sets the default
ACPI DOS value to 0, which lets the OS handle toggling of display output
but still leaves the BIOS handling brightness levels automatically when
connecting/disconnecting AC.
We want the OS to handle both where possible, so a better default would
be to set this to 4.
This likely will regress systems using proprietary video drivers which
will need to change this setting back using the sysfs interfaces.

all change inside the kernel and module-init-tools has never been kept

TEAC's UD-H01 (and probably other devices) have a gap in the interface
number allocation of their descriptors:
Configuration Descriptor:
bLength 9
bDescriptorType 2
wTotalLength 220
bNumInterfaces 3
[...]
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 0
bAlternateSetting 0
[...]
Interface Association:
bLength 8
bDescriptorType 11
bFirstInterface 2
bInterfaceCount 2
bFunctionClass 1 Audio
bFunctionSubClass 0
bFunctionProtocol 32
iFunction 4
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 2
bAlternateSetting 0
[...]
Once a configuration is selected, usb_set_configuration() walks the
known interfaces of a given configuration and calls find_iad() on
each of them to set the interface association pointer the interface
is included in.
The problem here is that the loop variable is taken for the interface
number in the comparison logic that gathers the association. Which is
fine as long as the descriptors are sane.
In the case above, however, the logic gets out of sync and the
interface association fields of all interfaces beyond the interface
number gap are wrong.
Fix this by passing the interface's bInterfaceNumber to find_iad()
instead.

If the platform_data is not set, pdata will be uninitialized value.
Since the driver has the following code, if the condition is true when
the pdata is uninitialized value, the driver may jump to the illegal
phy_init().
if (pdata && pdata->phy_init)
pdata->phy_init();
This patch also fixes the following warning:
CC drivers/usb/host/ehci-hcd.o
drivers/usb/host/ehci-sh.c: In function ‘ehci_hcd_sh_probe’:
drivers/usb/host/ehci-sh.c:104: warning: ‘pdata’ may be used uninitialized in this function

Currently CDC-ACM devices stay throttled when their TTY is closed while
throttled, stalling further communication attempts after the next open.
Unthrottling during open/activate got lost starting with kernel
3.0.0 and this patch reintroduces it.

Its observed with some PHY, the 60Mhz clock gets
cut too soon for OMAP EHCI, leaving OMAP-EHCI in a bad state.
So on starting port suspend, make sure the 60Mhz clock to EHCI
is kept alive using an internal clock, so that EHCi can cleanly
transition its hw state machine on a port suspend.
Its not proven if this is the issue hit on USB3333,
but the symptoms look very similar.
