fa70fe44ab USB: cxacru: export detailed device info through sysfs
When the device is polled for status there is a lot of useful status
information available that is ignored.  This patch stores the device info
array when the status is polled and adds sysfs files to the usb device to
allow userspace to query it.  Since the device updates its status
internally once a second the poll time is changed to this, and
round_jiffies_relative is used to avoid waking the cpu unnecessarily.

e9b8daf31b usbatm: create sysfs link "device" from atm class device to usb interface
There is currently no path from the ATM device in /sys to the USB device's
interface that the driver is using; this patch creates a "device" symlink.  It
is then possible to get to the cxacru ADSL statistics
(http://lkml.org/lkml/2007/2/23/328):

/sys/class/atm/cxacru0/device $ ls *_rate *_margin *_attenuation
downstream_attenuation  downstream_snr_margin  upstream_rate
downstream_rate         upstream_attenuation   upstream_snr_margin

If this link is not appropriate I'd have to create device files in
/sys/class/atm/cxacru0 instead - which seems less appropriate since the ADSL
statistics are for the USB device not ATM (which is running over the ADSL).

From: Johannes Berg <johannes@sipsolutions.net>
Subject: suspend: add arch irq disable/enable hooks

For powermac, we need to do some things between suspending devices and
device_power_off, for example setting the decrementer. This patch
allows architectures to define arch_s2ram_{en,dis}able_irqs in their
asm/suspend.h to have control over this step.

075c177152 define platform wakeup hook, use in pci_enable_wake()
This defines a platform hook to enable/disable a device as a wakeup event
source.  It's initially for use with ACPI, but more generally it could be used
whenever enable_irq_wake()/disable_irq_wake() don't suffice.

The hook is called -- if available -- inside pci_enable_wake(); and the
semantics of that call are enhanced so that support for PCI PME# is no longer
needed.  It can now work for devices with "legacy PCI PM", when platform
support allows it.  (That support would use some board-specific signal for for
the same purpose as PME#.)

057f6c019f security: prevent permission checking of file removal via sysfs_remove_group()
Prevent permission checking from being performed when the kernel wants to
unconditionally remove a sysfs group, by introducing an kernel-only variant
of lookup_one_len(), lookup_one_len_kern().

Additionally, as sysfs_remove_group() does not check the return value of
the lookup before using it, a BUG_ON has been added to pinpoint the cause
of any problems potentially caused by this (and as a form of annotation).

fa1a8c23eb s390: cio: Delay uevents for subchannels
We often have the situation that we register a subchannel and start device
recognition, only to find out that the device is not usable after all, which
triggers an unregister of the subchannel.  This often happens on hundreds of
subchannels on a LPAR, leading to a storm of events which aren't of any use. 
Therefore, use uevent_suppress to delay the KOBJ_ADD uevent for a subchannel
until we know that its ccw_device is to be registered.

bdc4960a0b Driver core: switch firmware_class to uevent_suppress.
Use uevent_suppress instead of returning an error code in
firmware_uevent(). Get rid of the now unneeded FW_STATUS_READY
and FW_STATUS_READY_NOHOTPLUG.

83b5fb4cce Driver core: suppress uevents via filter
Suppress uevents for devices if uevent_suppress is set via
dev_uevent_filter(). This makes the driver core suppress all device
uevents, not just the add event in device_add().
