| * clocksource/drivers/arm_arch_timer: Validate CNTFRQ after enabling frameArd Biesheuvel2017-10-191-17/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ACPI GTDT code validates the CNTFRQ field of each MMIO timer frame against the CNTFRQ system register of the current CPU, to ensure that they are equal, which is mandated by the architecture. However, reading the CNTFRQ field of a frame is not possible until the RFRQ bit in the frame's CNTACRn register is set, and doing so before that willl produce the following error: arch_timer: [Firmware Bug]: CNTFRQ mismatch: frame @ 0x00000000e0be0000: (0x00000000), CPU: (0x0ee6b280) arch_timer: Disabling MMIO timers due to CNTFRQ mismatch arch_timer: Failed to initialize memory-mapped timer. The reason is that the CNTFRQ field is RES0 if access is not enabled. So move the validation of CNTFRQ into the loop that iterates over the timers to find the best frame, but defer it until after we have selected the best frame, which should also have enabled the RFRQ bit.

| * clocksource: Improve GENERIC_CLOCKEVENTS dependencyArnd Bergmann2017-10-191-41/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We regularly run into build errors when a clocksource driver selects CONFIG_TIMER_OF while CONFIG_GENERIC_CLOCKEVENTS is disabled: In file included from drivers/clocksource/timer-of.c:25:0: drivers/clocksource/timer-of.h:35:28: error: field 'clkevt' has incomplete type At the moment, three drivers can show this behavior: ARMV7M_SYSTICK, CLKSRC_ST_LPC and CLKSRC_NPS. We could add further dependencies as we did many times, but I have looked a little bit more at what architectures are left that don't use GENERIC_CLOCKEVENTS, and this shows that there is a better solution. On arch/frv and arch/ia64, we never select CONFIG_GENERIC_CLOCKEVENTS and we also don't use ARCH_USES_GETTIMEOFFSET, which would block the clocksource Kconfig menu. On m68k, some platforms use CONFIG_GENERIC_CLOCKEVENTS, some use ARCH_USES_GETTIMEOFFSET, and some use neither of them. The good news is that there is no configuration that does not set CONFIG_GENERIC_CLOCKEVENTS but that wants to enable any of the Kconfig symbols in the menu, so we can simply replace the dependency with the stricter one. While in theory one could have a clocksource driver without the clockevent infrastructure, this seems unlikely to be relevant in the future any more. We can probably drop some of the other dependencies as well now, e.g. there should generally be no reason to depend on CONFIG_ARM unless the driver uses architecture specific assembly.

| * | rtc: Allow rtc drivers to specify the tv_nsec value for ntpJason Gunthorpe2017-10-302-15/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ntp is currently hardwired to try and call the rtc set when wall clock tv_nsec is 0.5 seconds. This historical behaviour works well with certain PC RTCs, but is not universal to all rtc hardware. Change how this works by introducing the driver specific concept of set_offset_nsec, the delay between current wall clock time and the target time to set (with a 0 tv_nsecs). For x86-style CMOS set_offset_nsec should be -0.5 s which causes the last second to be written 0.5 s after it has started. For compat with the old rtc_set_ntp_time, the value is defaulted to + 0.5 s, which causes the next second to be written 0.5s before it starts, as things were before this patch. Testing shows many non-x86 RTCs would like set_offset_nsec ~= 0, so ultimately each RTC driver should set the set_offset_nsec according to its needs, and non x86 architectures should stop using update_persistent_clock64 in order to access this feature. Future patches will revise the drivers as needed. Since CMOS and RTC now have very different handling they are split into two dedicated code paths, sharing the support code, and ifdefs are replaced with IS_ENABLED.

Adds a pointer back to the policy, and drops the definition of init_timer_pinned_deferrable().

| * | ata_piix: Add Fujitsu-Siemens Lifebook S6120 to short cable IDsVille Syrjälä2017-09-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fujitsu-Siemens Lifebook S6120 misdetects the cable type for some drives. The problematic one in this case is an mSATA SSD hooked up via a mSATA->PATA bridge. With regular hard disks the detection seems to work correctly. Strangely an older Lifebook model (S6020) detects the cable as 80c with the mSATA SSD, even if using the exact same flex cable.
