There is no point in calling suspend/resume for unused clockevents as they are already stopped and disabled. This is really important for AT91 as the hardware is a trainwreck and takes ages to synchronize.

Ingo suggested that the timekeeping debugging variables recently added should not be global, and should be tied to the timekeeper's read_base. Thus this patch implements that suggestion. This version is different from the earlier versions as it keeps the variables in the timekeeper structure rather then in the tkr.

This patch series introduces a new function u32 ktime_get_resolution_ns(void) which allows to clean up some driver code. In particular the IIO subsystem has a function to provide timestamps for events but no means to get their resolution. So currently the dht11 driver tries to guess the resolution in a rather messy and convoluted way. We can do much better with the new code. This API is not designed to be exposed to user space. This has been tested on i386, sunxi and mxs.

To avoid getting spurious interrupts on a tickless CPU, clockevent device can now be stopped by switching to ONESHOT_STOPPED state. The natural place for handling this transition is tick_program_event(). On 'expires == KTIME_MAX', we skip programming the event and so we need to fix such call sites as well, to always call tick_program_event() irrespective of the expires value. Once the clockevent device is required again, check if it was earlier put into ONESHOT_STOPPED state. If yes, switch its state to ONESHOT before programming its event. To make sure we haven't missed any corner case, add a WARN() for the case where we try to reprogram clockevent device while we aren't configured in ONESHOT_STOPPED state.

由 Viresh Kumar 提交于
When no timers/hrtimers are pending, the expiry time is set to a special value: 'KTIME_MAX'. This normally happens with NO_HZ_{IDLE|FULL} in both LOWRES/HIGHRES modes. When 'expiry == KTIME_MAX', we either cancel the 'tick-sched' hrtimer (NOHZ_MODE_HIGHRES) or skip reprogramming clockevent device (NOHZ_MODE_LOWRES). But, the clockevent device is already reprogrammed from the tick-handler for next tick. As the clock event device is programmed in ONESHOT mode it will at least fire one more time (unnecessarily). Timers on few implementations (like arm_arch_timer, etc.) only support PERIODIC mode and their drivers emulate ONESHOT over that. Which means that on these platforms we will get spurious interrupts periodically (at last programmed interval rate, normally tick rate). In order to avoid spurious interrupts, the clockevent device should be stopped or its interrupts should be masked. A simple (yet hacky) solution to get this fixed could be: update hrtimer_force_reprogram() to always reprogram clockevent device and update clockevent drivers to STOP generating events (or delay it to max time) when 'expires' is set to KTIME_MAX. But the drawback here is that every clockevent driver has to be hacked for this particular case and its very easy for new ones to miss this. However, Thomas suggested to add an optional state ONESHOT_STOPPED to solve this problem: lkml.org/lkml/2014/5/9/508. This patch adds support for ONESHOT_STOPPED state in clockevents core. It will only be available to drivers that implement the state-specific callbacks instead of the legacy ->set_mode() callback.

Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf66 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d29 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again.

In the below two commits (see Fixes) we have periodic timers that can stop themselves when they're no longer required, but need to be (re)-started when their idle condition changes. Further complications is that we want the timer handler to always do the forward such that it will always correctly deal with the overruns, and we do not want to race such that the handler has already decided to stop, but the (external) restart sees the timer still active and we end up with a 'lost' timer. The problem with the current code is that the re-start can come before the callback does the forward, at which point the forward from the callback will WARN about forwarding an enqueued timer. Now, conceptually its easy to detect if you're before or after the fwd by comparing the expiration time against the current time. Of course, that's expensive (and racy) because we don't have the current time. Alternatively one could cache this state inside the timer, but then everybody pays the overhead of maintaining this extra state, and that is undesired. The only other option that I could see is the external timer_active variable, which I tried to kill before. I would love a nicer interface for this seemingly simple 'problem' but alas.

In commit 8ff16cf7 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation.

The ELPA bit in PageGrain is all about large *physical* addresses, so correct the reference to "large virtual address" in the comment above where it is set for MIPS64.

cpu_set was removed (along with a bunch of cpumask helpers) by commit 2f0f267e ("cpumask: remove deprecated functions."). Fix this by replacing cpu_set with cpumask_set_cpu. Without this fix the following error is triggered when CONFIG_MIPS_MT_FPAFF=y. arch/mips/kernel/smp-cps.c: In function 'cps_smp_setup': arch/mips/kernel/smp-cps.c:95:3: error: implicit declaration of function 'cpu_set' [-Werror=implicit-function-declaration] Fixes: 90db024f ("MIPS: smp-cps: cpu_set FPU mask if FPU present") Signed-off-by: NEzequiel Garcia <ezequiel.garcia@imgtec.com> Acked-by: NNiklas Cassel <niklass@axis.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/9912/Signed-off-by: NRalf Baechle <ralf@linux-mips.org>
