      cpuidle: menu: Retain tick when shallow state is selected · 757ab15c
      Rafael J. Wysocki authored
      The case addressed by commit 5ef499cd (cpuidle: menu: Handle
      stopped tick more aggressively) in the stopped tick case is present
      when the tick has not been stopped yet too.  Namely, if only two CPU
      idle states, shallow state A with target residency significantly
      below the tick boundary and deep state B with target residency
      significantly above it, are available and the predicted idle
      duration is above the tick boundary, but below the target residency
      of state B, state A will be selected and the CPU may spend indefinite
      amount of time in it, which is not quite energy-efficient.
      
      However, if the tick has not been stopped yet and the governor is
      about to select a shallow idle state for the CPU even though the idle
      duration predicted by it is above the tick boundary, it should be
      fine to wake up the CPU early, so the tick can be retained then and
      the governor will have a chance to select a deeper state when it runs
      next time.
      
      [Note that when this really happens, it will make the idle duration
       predictor believe that the CPU might be idle longer than predicted,
       which will make it more likely to predict longer idle durations going
       forward, but that will also cause deeper idle states to be selected
       going forward, on average, which is what's needed here.]

       "These fix the main idle loop and the menu cpuidle governor, clean up
        the latter, fix a mistake in the PCI bus type's support for system
        suspend and resume, fix the ondemand and conservative cpufreq
        governors, address a build issue in the system wakeup framework and
        make the ACPI C-states desciptions less confusing.
      
        Specifics:
      
         - Make the idle loop handle stopped scheduler tick correctly (Rafael
           Wysocki).
      
         - Prevent the menu cpuidle governor from letting CPUs spend too much
           time in shallow idle states when it is invoked with scheduler tick
           stopped and clean it up somewhat (Rafael Wysocki).
      
         - Avoid invoking the platform firmware to make the platform enter the
           ACPI S3 sleep state with suspended PCIe root ports which may
           confuse the firmware and cause it to crash (Rafael Wysocki).
      
         - Fix sysfs-related race in the ondemand and conservative cpufreq
           governors which may cause the system to crash if the governor
           module is removed during an update of CPU frequency limits (Henry
           Willard).
      
         - Select SRCU when building the system wakeup framework to avoid a
           build issue in it (zhangyi).

      h8300:let the checker know that size_t is ulong · 1b803a35
      Luc Van Oostenryck authored
      All 64bit archs use unsigned long for size_t and most 32bit
      archs use 'unsigned int'. By default, this is what is assumed
      by sparse.
      
      However, on h8300 (a 32bit arch) size_t is unsigned long which
      can led sparse to emit wrong warnings.
      
      Fix this by passing to sparse the flag -msize-long, telling it
      that size_t is unsigned long.

      Commit 0fa1c579 ("of/fdt: use memblock_virt_alloc for early alloc")
      inadvertently switched the DT unflattening allocations from memblock to
      bootmem which doesn't work because the unflattening happens before
      bootmem is initialized. Swapping the order of bootmem init and
      unflattening could also fix this, but removing bootmem is desired. So
      enable NO_BOOTMEM on h8300 like other architectures have done.

      Pull i2c updates from Wolfram Sang:
      
       - the core has now a lockless variant of i2c_smbus_xfer. Some open
         coded versions of this got removed in drivers. This also enables
         proper SCCB support in regmap.
      
       - locking got a more precise naming. i2c_{un}lock_adapter() had to go,
         and we know use i2c_lock_bus() consistently with flags like
         I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity.
      
       - the gpio fault injector got a new delicate testcase
      
       - the bus recovery procedure got fixed to handle the new testcase
         correctly
      
       - a new quirk flag for controllers not able to handle zero length
         messages together with driver updates to use it
      
       - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl
         family S900

      sparc: fix KBUILD_DEFCONFIG for ARCH=sparc32 · c84ca616
      Masahiro Yamada authored
      As commit 5ba80096 ("kbuild: update ARCH alias info for sparc")
      addressed, SPARC accepts ARCH=sparc32 as an alias.
      
      However, arch/sparc/Makefile wrongly sets KBUILD_DEFCONFIG, then
      sparc64_defconfig is chosen as the base configuration for ARCH=sparc32.
      
        $ make ARCH=sparc32 defconfig
        *** Default configuration is based on 'sparc64_defconfig'
        #
        # configuration written to .config
        #
      
      Fix the logic to choose sparc64_defconfig only when ARCH=sparc64.

      sparc32: split ramdisk detection and reservation to a helper function · 8818d89c
      Mike Rapoport authored
      The detection and reservation of ramdisk memory were separated to allow
      bootmem bitmap initialization after the ramdisk boundaries are detected.
      Since the bootmem initialization is removed, the reservation of ramdisk
      memory is done immediately after its boundaries are found.
      
      Split the entire block into a separate helper function.

      Pull tracing updates from Steven Rostedt:
      
       - Restructure of lockdep and latency tracers
      
         This is the biggest change. Joel Fernandes restructured the hooks
         from irqs and preemption disabling and enabling. He got rid of a lot
         of the preprocessor #ifdef mess that they caused.
      
         He turned both lockdep and the latency tracers to use trace events
         inserted in the preempt/irqs disabling paths. But unfortunately,
         these started to cause issues in corner cases. Thus, parts of the
         code was reverted back to where lockdep and the latency tracers just
         get called directly (without using the trace events). But because the
         original change cleaned up the code very nicely we kept that, as well
         as the trace events for preempt and irqs disabling, but they are
         limited to not being called in NMIs.
      
       - Have trace events use SRCU for "rcu idle" calls. This was required
         for the preempt/irqs off trace events. But it also had to not allow
         them to be called in NMI context. Waiting till Paul makes an NMI safe
         SRCU API.
      
       - New notrace SRCU API to allow trace events to use SRCU.
      
       - Addition of mcount-nop option support
      
       - SPDX headers replacing GPL templates.
      
       - Various other fixes and clean ups.
      
       - Some fixes are marked for stable, but were not fully tested before
         the merge window opened.
