2020-07-23clocksource/drivers/ingenic: Add high resolution timer support for SMP/SMT.周琰杰 (Zhou Yanjie)
Enable clock event handling on per CPU core basis. Make sure that interrupts raised on the first core execute event handlers on the correct CPU core. This driver is required by Ingenic processors that support SMP/SMT, such as JZ4780 and X2000. Tested-by: H.

2020-05-23clocksource/drivers/timer-versatile: Clear OF_POPULATED flagSaravana Kannan
The commit 4f41fe386a94 ("clocksource/drivers/timer-probe: Avoid creating dead devices") broke the handling of arm,vexpress-sysreg [1]. The arm,vexpress-sysreg device is handled by both timer-versatile.c and drivers/mfd/vexpress-sysreg.c. While the timer driver doesn't use the device, the mfd driver still needs a device to probe. So, this patch clears the OF_POPULATED flag to continue creating the device.

2020-05-23clocksource: mips-gic-timer: Mark GIC timer as unstable if ref clock changesSerge Semin
Currently clocksource framework doesn't support the clocks with variable frequency. Since MIPS GIC timer ticks rate might be unstable on some platforms, we must make sure that it justifies the clocksource requirements. MIPS GIC timer is incremented with the CPU cluster reference clocks rate. So in case if CPU frequency changes, the MIPS GIC tick rate changes synchronously. Due to this the clocksource subsystem can't rely on the timer to measure system clocks anymore. This commit marks the MIPS GIC based clocksource as unstable if reference clock (normally it's a CPU reference clocks) rate changes. The clocksource will execute a watchdog thread, which lowers the MIPS GIC timer rating to zero and fallbacks to a new stable one. Note we don't need to set the CLOCK_SOURCE_MUST_VERIFY flag to the MIPS GIC clocksource since normally the timer is stable. The only reason why it gets unstable is due to the ref clock rate change, which event we detect here in the driver by means of the clocks event notifier.

2020-05-23clocksource: mips-gic-timer: Register as sched_clockPaul Burton
The MIPS GIC timer is well suited for use as sched_clock, so register it as such. Whilst the existing gic_read_count() function matches the prototype needed by sched_clock_register() already, we split it into 2 functions in order to remove the need to evaluate the mips_cm_is64 condition within each call since sched_clock should be as fast as possible. Note the sched clock framework needs the clock source being stable in order to rely on it. So we register the MIPS GIC timer as schedule clocks only if it's, if either the system doesn't have CPU-frequency enabled or the CPU frequency is changed by means of the CPC core clock divider available on the platforms with CM3 or newer.

2020-05-23clocksource: dw_apb_timer_of: Fix missing clockevent timersSerge Semin
Commit 100214889973 ("clocksource: dw_apb_timer_of: use clocksource_of_init") replaced a publicly available driver initialization method with one called by the timer_probe() method available after CLKSRC_OF. In current implementation it traverses all the timers available in the system and calls their initialization methods if corresponding devices were either in dtb or in acpi. But if before the commit any number of available timers would be installed as clockevent and clocksource devices, after that there would be at most two. The rest are just ignored since default case branch doesn't do anything. I don't see a reason of such behaviour, neither the commit message explains it. Moreover this might be wrong if on some platforms these timers might be used for different purpose, as virtually CPU-local clockevent timers and as an independent broadcast timer. So in order to keep the compatibility with the platforms where the order of the timers detection has some meaning, lets add the secondly discovered timer to be of clocksource/sched_clock type, while the very first and the others would provide the clockevents service.

2020-05-23clocksource: dw_apb_timer: Affiliate of-based timer with any CPUSerge Semin
Currently any DW APB Timer device detected in OF is bound to CPU #0. Doing so is redundant since DW APB Timer isn't CPU-local timer, but as having APB interface is normally accessible from any CPU in the system. By artificially affiliating the DW timer to the very first CPU we may and in our case will make the clockevent subsystem to decline the more performant real CPU-local timers selection in favor of in fact non-local and accessible over a slow bus - DW APB Timers. Let's not affiliate the of-detected DW APB Timers to any CPU. By doing so the clockevent framework would prefer to select the real CPU-local timer instead of DW APB one. Otherwise if there is no other than DW APB device for clockevents tracking then it will be selected.

2020-05-23clocksource: dw_apb_timer: Make CPU-affiliation being optionalSerge Semin
Currently the DW APB Timer driver binds each clockevent timers to a particular CPU. This isn't good for multiple reasons. First of all seeing the device is placed on APB bus (which makes it accessible from any CPU core), accessible over MMIO and having the DYNIRQ flag set we can be sure that manually binding the timer to any CPU just isn't correct. By doing so we just set an extra limitation on device usage. This also doesn't reflect the device actual capability, since by setting the IRQ affinity we can make it virtually local to any CPU. Secondly imagine if you had a real CPU-local timer with the same rating and the same CPU-affinity. In this case if DW APB timer was registered first, then due to the clockevent framework tick-timer selection procedure we'll end up with the real CPU-local timer being left unselected for clock-events tracking. But on most of the platforms (MIPS/ARM/etc) such timers are normally embedded into the CPU core and are accessible with much better performance then devices placed on APB. For instance in MIPS architectures there is r4k-timer, which is CPU-local, assigned with the same rating, and normally its clockevent device is registered after the platform-specific one. So in order to fix all of these issues let's make the DW APB Timer CPU affinity being optional and deactivated by passing a negative CPU id, which will effectively set the DW APB clockevent timer cpumask to 'cpu_possible_mask'.

2020-05-23clocksource/drivers/timer-ti-dm: Add clockevent and clocksource supportTony Lindgren
We can move the TI dmtimer clockevent and clocksource to live under drivers/clocksource if we rely only on the clock framework, and handle the module configuration directly in the clocksource driver based on the device tree data. This removes the early dependency with system timers to the interconnect related code, and we can probe pretty much everything else later on at the module_init level. Let's first add a new driver for timer-ti-dm-systimer based on existing arch/arm/mach-omap2/timer.c. Then let's start moving SoCs to probe with device tree data while still keeping the old timer.c. And eventually we can just drop the old timer.c. Let's take the opportunity to switch to use readl/writel as pointed out by Daniel Lezcano <daniel.lezcano@linaro.org>. This allows further clean-up of the timer-ti-dm code the a lot of the shared helpers can just become static to the non-syster related code. Note the boards can optionally configure different timer source clocks if needed with assigned-clocks and assigned-clock-parents.

2020-04-27clocksource/drivers/versatile: Allow CONFIG_CLKSRC_VERSATILE to be disabledRob Herring
The timer-versatile driver provides a sched_clock for certain Arm Ltd. reference platforms. Specifically, it is used on Versatile and 32-bit VExpress. It is not needed for those platforms with an arch timer (all the 64-bit ones) yet CONFIG_MFD_VEXPRESS_SYSREG does still need to be enabled. In that case, the timer-versatile can only be disabled when COMPILE_TEST is enabled which is not desirable. Let's use the sub-arch kconfig symbols instead. Realview platforms don't have the sysregs that this driver uses so correct the help text.

2020-04-10mm/vma: introduce VM_ACCESS_FLAGSAnshuman Khandual
There are many places where all basic VMA access flags (read, write, exec) are initialized or checked against as a group. One such example is during page fault. Existing vma_is_accessible() wrapper already creates the notion of VMA accessibility as a group access permissions. Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which will not only reduce code duplication but also extend the VMA accessibility concept in general.
