Commit: 65cd4f6c ("arch_timer: Move to generic sched_clock framework") added code to register the arch_sys_counter in arch_timer_register(), but it is already registered in arch_counter_register(). This results in the timer being added to the clocksource list twice, therefore causing an infinite loop in the list. Remove the duplicate registration and register the scheduler clock after the original registration instead. This fixes a hang during boot on Tegra114 (Cortex-A15). [ While I've only tested this on Tegra114, I suspect the same hang during boot happens for all processors that use this clock source. ] Signed-off-by: NThierry Reding <treding@nvidia.com> Acked-by: NJohn Stultz <john.stultz@linaro.org> Cc: Stephen Boyd <sboyd@codeaurora.org> Cc: Will Deacon <will.deacon@arm.com> Cc: Stephen Warren <swarren@wwwdotorg.org> Cc: linux-arm-kernel@lists.infradead.org Cc: Daniel Lezcano <daniel.lezcano@linaro.org> Link: http://lkml.kernel.org/r/1381843911-31962-1-git-send-email-treding@nvidia.comSigned-off-by: NIngo Molnar <mingo@kernel.org>

Register with the generic sched_clock framework now that it supports 64 bits. This fixes two problems with the current sched_clock support for machines using the architected timers. First off, we don't subtract the start value from subsequent sched_clock calls so we can potentially start off with sched_clock returning gigantic numbers. Second, there is no support for suspend/resume handling so problems such as discussed in 6a4dae5e (ARM: 7565/1: sched: stop sched_clock() during suspend, 2012-10-23) can happen without this patch. Finally, it allows us to move the sched_clock setup into drivers clocksource out of the arch ports.

Pull ARM clocksource/clockevents updates from Daniel Lezcano: * Will Deacon and Sudeep KarkadaNagesha implemented the event stream for architected timer. The event streams can be used to impose a timeout on a wfe, to safeguard against any programming error in case an expected event is not generated or even to implement wfe-based timeouts for userspace locking implementations. Some files fall under the arm maintainers' umbrella but those changes have been reviewed and acked by the relevant people (Catalin Marinas and Olof Johansson). * Boris Brezillon improved the tcb_clksrc driver by removing a deprecated flag, checking return code values and using functions from the common clock framework.

Pull (mostly) ARM clocksource driver updates from Daniel Lezcano: " - Soren Brinkmann added FEAT_PERCPU to a clock device when it is local per cpu. This feature prevents the clock framework to choose a per cpu timer as a broadcast timer. This problem arised when the ARM global timer is used when switching to the broadcast timer which is the case now on Xillinx with its cpuidle driver. - Stephen Boyd extended the generic sched_clock code to support 64bit counters and removes the setup_sched_clock deprecation, as that causes lots of warnings since there's still users in the arch/arm tree. He added also the CLOCK_SOURCE_SUSPEND_NONSTOP flag on the architected timer as they continue counting during suspend. - Uwe Kleine-König added some missing __init sections and consolidated the code by moving the of_node_put call from the drivers to the function clocksource_of_init.

The ARM architected timers keep counting during suspend so we can mark this clocksource with the CLOCK_SOURCE_SUSPEND_NONSTOP flag. This flag will indicate that this clocksource can be used for calculating suspend time and injecting sleep time into the timekeeping core. This should be more accurate than using an external RTC or architecture specific persistent clock.

On most ARM systems the per-cpu clockevents are truly per-cpu in the sense that they can't be controlled on any other CPU besides the CPU that they interrupt. If one of these clockevents were to become a broadcast source we will run into a lot of trouble because the broadcast source is enabled on the first CPU to go into deep idle (if that CPU suffers from FEAT_C3_STOP) and that could be a different CPU than what the clockevent is interrupting (or even worse the CPU that the clockevent interrupts could be offline). Theoretically it's possible to support per-cpu clockevents as the broadcast source but so far we haven't needed this and supporting it is rather complicated. Let's just deny the possibility for now until this becomes a reality (let's hope it never does!).

With VIRT_CPU_ACCOUNTING_GEN, cputime_t becomes 64-bit. In order to use that feature, arch code should be audited to ensure there are no races in concurrent read/write of cputime_t. For example, reading/writing 64-bit cputime_t on some 32-bit arches may require multiple accesses for low and high value parts, so proper locking is needed to protect against concurrent accesses. Therefore, add CONFIG_HAVE_VIRT_CPU_ACCOUNTING_GEN which arches can enable after they've been audited for potential races. This option is automatically enabled on 64-bit platforms.
