| * llist: llist_add() can use llist_add_batch()Oleg Nesterov2013-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | llist_add(new, head) can simply use llist_add_batch(new, new, head), no need to duplicate the code. This obviously uninlines llist_add() and to me this is a win. But we can make llist_add_batch() inline if this is desirable, in this case gcc can notice that new_first == new_last if the caller is llist_add().

| * llist: fix/simplify llist_add() and llist_add_batch()Oleg Nesterov2013-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. This is mostly theoretical, but llist_add*() need ACCESS_ONCE(). Otherwise it is not guaranteed that the first cmpxchg() uses the same value for old_entry and new_last->next. 2. These helpers cache the result of cmpxchg() and read the initial value of head->first before the main loop. I do not think this makes sense. In the likely case cmpxchg() succeeds, otherwise it doesn't hurt to reload head->first. I think it would be better to simplify the code and simply read ->first before cmpxchg().

| * fput: turn "list_head delayed_fput_list" into llist_headOleg Nesterov2013-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fput() and delayed_fput() can use llist and avoid the locking. This is unlikely path, it is not that this change can improve the performance, but this way the code looks simpler.

| * | Add trivial driver to disable Intel Smart ConnectMatthew Garrett2013-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel Smart Connect is an Intel-specific ACPI interface for configuring devices to wake up at regular intervals so they can pull down mail or other internet updates, and then go to sleep again. If a user enables this in Windows and then reboots into Linux, the device may wake up if it's put to sleep. Since there's no Linux userland support for any of this, the machine will then remain awake until something else puts it back to sleep. I haven't figured out all that much about how this works (there's a bunch of different ACPI calls available on the device), but this seems to be enough to turn it off. We can add more features to this driver if anyone ever cares about figuring out what the rest of the calls do or writing some Linux userspace to implement the rest of it.

| * | Add support driver for Intel Rapid Start TechnologyMatthew Garrett2013-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel Rapid Start Technology is a firmware-based suspend-to-disk implementation. Once placed in S3, the device will wake once either a timeout elapses or the battery reaches a critical level. It will then resume to the firmware and copy the contents of RAM to a specialised partition, and then power off the machine. If the user turns the machine back on the firmware will copy the contents of the partition back to RAM and then resume from S3 as normal. This driver provides an interface for configuring the wakeup events and timeout. It still requires firmware support and an appropriate suspend partition.

Starting from v7, additional information (to be interpreted) is stored in the remaining bits (packets[3] & 0x1c). In addition, the value stored in (packet[0] & 0x0c) is no longer a constant but contains additional information yet to be deciphered. This change should be backwards compatible with v6 hardware.

To make sure we actually get an ecmp route while searching for the first one in this fib6_node's leafs, also make sure it matches the ecmp route assumptions. v2: a) Removed RTF_EXPIRE check in dst.from chain. The check of RTF_ADDRCONF already ensures that this route, even if added again without RTF_EXPIRES (in case of a RA announcement with infinite timeout), does not cause the rt6i_nsiblings logic to go wrong if a later RA updates the expiration time later. v3: a) Allow RTF_EXPIRES routes to enter the ecmp route set. We have to do so, because an pmtu event could update the RTF_EXPIRES flag and we would not count this route, if another route joins this set. We now filter only for RTF_GATEWAY|RTF_ADDRCONF|RTF_DYNAMIC, which are flags that don't get changed after rt6_info construction.

This patch should fix it, the reporter wandered off after filing this bz: https://bugzilla.redhat.com/show_bug.cgi?id=954170 and I don't have hardware to test, but the fix is pretty straightforward, so I figured I'd post it for review.
