The initial method to do this was to simply call rtc_set_alarm() with the value read from hardware. However, this may cause problems as rtc_set_alarm may enable interupts, and the RTC alarm might fire, which can cause invalid pointer dereferencing since the RTC registration is not complete. This patch solves the issue by initializing the rtc_device.aie_timer y hand via rtc_initialize_alarm(). This avoids any calls to the RTC hardware which might enable interrupts too early.

The device's ID is blacklisted in cdc_ether.c and is white-listed in this new driver because of the quirks needed to make it useful. The modem's firmware exposes a CDC ACM port for modem control and a CDC Ethernet port for network data. The descriptors look fine but both ports actually are some sort of multiplexers requiring non- standard headers added/removed from every packet or they get ignored. All information is based on a usb traffic log from a Windows machine. On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.

This patch converts connector to do synchronous message processing by invoking the registered callback handler directly from the netlink receive function. In order to avoid invoking the callback with connector locks held, a reference count is added to struct cn_callback_entry, the reference is taken when finding a matching callback entry on the device's queue_list and released after the callback handler has been invoked.

The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag. Signed-off-by: Arnd Bergmann Tested-by: Andy Green Signed-off-by: David S.

To some degree that is unavoidable (stacked DM devices force this late checking). But for most DM devices (which aren't stacking on other DM devices) the ideal time to verify all integrity profiles match is during table load. Introduce the notion of an "initialized" integrity profile: a profile that was blk_integrity_register()'d with a non-NULL 'blk_integrity' template. Add blk_integrity_is_initialized() to allow checking if a profile was initialized. Update DM integrity support to: - check all devices with _initialized_ integrity profiles match during table load; uninitialized profiles (e.g. for underlying DM device(s) of a stacked DM device) are ignored. - disallow a table load that would result in an integrity profile that conflicts with a DM device's existing (in-use) integrity profile - avoid clearing an existing integrity profile - validate all integrity profiles match during resume; but if they don't all we can do is report the mismatch (during resume we're past the point of no return) Signed-off-by: Mike Snitzer Cc: Martin K.

Wysocki" Date: Mon, 11 Apr 2011 22:54:42 +0200 Subject: PM / Hibernate: Introduce CONFIG_HIBERNATE_CALLBACKS Xen save/restore is going to use hibernate device callbacks for quiescing devices and putting them back to normal operations and it would need to select CONFIG_HIBERNATION for this purpose. However, that also would cause the hibernate interfaces for user space to be enabled, which might confuse user space, because the Xen kernels don't support hibernation. Moreover, it would be wasteful, as it would make the Xen kernels include a substantial amount of code that they would never use. To address this issue introduce new power management Kconfig option CONFIG_HIBERNATE_CALLBACKS, such that it will only select the code that is necessary for the hibernate device callbacks to work and make CONFIG_HIBERNATION select it. Then, Xen save/restore will be able to select CONFIG_HIBERNATE_CALLBACKS without dragging the entire hibernate code along with it. Signed-off-by: Rafael J.

Upstream libmount (in the util-linux tree) has been fixed, but until that fix actually percolates up to users, we'd better not expose this change in the kernel. Let's revisit this later (possibly by exposing the UUID without any '-' characters in it, avoiding the user-space bug).

At present, remotes with an images or photos or pictures button use any number of different keycodes which sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA, KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right. In my mind, KEY_MEDIA should be something more like a media center application launcher (and I'd like to standardize on that for things like the windows media center button on the mce remotes). KEY_CAMERA is used in a lot of webcams, and typically means "take a picture now". KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION might be the closest fit here, if you think "photo slide show", but it may well be more intended for "run application in full-screen presentation mode" or to launch something like magicpoint, I dunno. And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL Image Browser, the meaning of which I think is crystal-clear. I believe AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser by KEY_VIDEO, so I'm also adding appropriate comments next to those keys.
