2011-05-23hrtimers: Reorder clock basesThomas Gleixner
The ordering of the clock bases is historical due to the CLOCK_REALTIME and CLOCK_MONOTONIC constants. Now the hrtimer bases have their own enumeration due to the gap between CLOCK_MONOTONIC and CLOCK_BOOTTIME. So we can be more clever as most timers end up on the CLOCK_MONOTONIC base due to the virtue of POSIX declaring that relative CLOCK_REALTIME timers are not affected by time changes. In desktop environments this is slowly changing as applications switch to absolute timers, but I've observed empty CLOCK_REALTIME bases often enough. There is no performance penalty or overhead when CLOCK_REALTIME timers are active, but in case they are not we don't skip over a full cache line.

2011-05-23timerfd: Manage cancelable timers in timerfdThomas Gleixner
Peter is concerned about the extra scan of CLOCK_REALTIME_COS in the timer interrupt. Yes, I did not think about it, because the solution was so elegant. I didn't like the extra list in timerfd when it was proposed some time ago, but with a rcu based list the list walk it's less horrible than the original global lock, which was held over the list iteration.

2011-05-23watchdog: Change the default timeout and configure nmi watchdog period based ↵Mandeep Singh Baines
on watchdog_thresh Before the conversion of the NMI watchdog to perf event, the watchdog timeout was 5 seconds. Now it is 60 seconds. For my particular application, netbooks, 5 seconds was a better timeout. With a short timeout, we catch faults earlier and are able to send back a panic. With a 60 second timeout, the user is unlikely to wait and will instead hit the power button, causing us to lose the panic info. This change configures the NMI period to watchdog_thresh and sets the softlockup_thresh to watchdog_thresh * 2. In addition, watchdog_thresh was reduced to 10 seconds as suggested by Ingo Molnar.

2011-05-23watchdog: Disable watchdog when thresh is zeroMandeep Singh Baines
This restores the previous behavior of softlock_thresh. Currently, setting watchdog_thresh to zero causes the watchdog kthreads to consume a lot of CPU. In addition, the logic of proc_dowatchdog_thresh and proc_dowatchdog_enabled has been factored into proc_dowatchdog.

Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h. The skbuff list traversal still had them. Quoth David Miller: "Please just remove the prefetches. Those are modelled after list.h as I intend to eventually convert SKB list handling to "struct list_head" but we're not there yet. Therefore if we kill prefetches from list.h we should kill it from these things in skbuff.h too."

2011-05-22netpoll: disable netpoll when enslave a deviceAmerigo Wang
V3: rename NETDEV_ENSLAVE to NETDEV_JOIN Currently we do nothing when we enslave a net device which is running netconsole. Neil pointed out that we may get weird results in such case, so let's disable netpoll on the device being enslaved. I think it is too harsh to prevent the device being ensalved if it is running netconsole. By the way, this patch also removes the NETDEV_GOING_DOWN from netconsole netdev notifier, because netpoll will check if the device is running or not and we don't handle NETDEV_PRE_UP neither.

KVM does not hold any references to rcu protected data when it switches CPU into a guest mode. In fact switching to a guest mode is very similar to exiting to userspase from rcu point of view. In addition CPU may stay in a guest mode for quite a long time (up to one time slice). Lets treat guest mode as quiescent state, just like we do with user-mode execution.

2011-05-20spinlock_up.h: include asm/processor.h in for cpu_relaxStephen Rothwell
Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h and this was a path to including asm/processor.h. We need to include it excplicitly now.

2011-05-20macvlan: remove one synchronize_rcu() callEric Dumazet
When one macvlan device is dismantled, we can avoid one synchronize_rcu() call done after deletion from hash list, since caller will perform a synchronize_net() call after its ndo_stop() call. Add a new netdev->dismantle field to signal this dismantle intent. Reduces RTNL hold time.

2011-05-19signal.h need a definition of struct task_structStephen Rothwell
This fixes these build errors on powerpc: In file included from arch/powerpc/mm/fault.c:18: include/linux/signal.h:239: error: 'struct task_struct' declared inside parameter list include/linux/signal.h:239: error: its scope is only this definition or declaration, which is probably not what you want include/linux/signal.h:240: error: 'struct task_struct' declared inside parameter list .. Exposed by commit e66eed651fd1 ("list: remove prefetching from regular list iterators"), which removed the include of <linux/prefetch.h> from <linux/list.h>. Without that, linux/signal.h no longer accidentally got the declaration of 'struct task_struct'. Fix by properly declaring the struct, rather than introducing any new header file dependency.
