      platform/mellanox: Add new ODM system types to mlx-platform · cbf7ff8c
      Vadim Pasternak authored
      Add new ODM system types, matched according to DMI_BOARD_NAME. The
      supported ODM Ids are: VMOD0001, VMOD0002, VMOD0003, VMOD0004, VMOD0005.
      Patch does not introduce new systems, but allows to ODM companies to set
      DMI_BOARD_VENDOR and DMI_PRODUCT_NAME on their own. It assumes that ODM
      company can't change DMI_BOARD_NAME.

      platform/mellanox: mlxreg-hotplug: add extra cycle for hotplug work queue · 4b5e32df
      Vadim Pasternak authored
      Add extra cycle for hotplug work queue to handle the case when a signal is
      It adds missed logic for signal acknowledge, by adding an extra run for
      received, but no specific signal assertion is detected. Such case
      theoretically can happen for example in case several units are removed or
      inserted at the same time. In this situation acknowledge for some signal
      can be missed at signal top aggreagation status level. The extra run will
      allow to handler to acknowledge the missed signal.
      
      The interrupt handling flow performs the next steps:
      (1)
      Enter mlxreg_hotplug_work_handler due to signal assertion.
      Aggregation status register is changed for example from 0xff to 0xfd
      (event signal group related to bit 1).
      (2)
      Mask aggregation interrupts, read aggregation status register and save it
      (0xfd) in aggr_cache, then traverse down to handle signal from groups
      related to the changed bit.
      (3)
      Read and mask group related signal.
      Acknowledge and unmask group related signal (acknowledge should clear
      aggregation status register from 0xfd back to 0xff).
      (4)
      Re-schedule work queue for the immediate execution.
      (5)
      Enter mlxreg_hotplug_work_handler due to re-scheduling.
      Aggregation status is changed from previous 0xfd to 0xff.
      Go over steps (2) - (5) and in case no new signal assertion
      is detected - unmask aggregation interrupts.
      
      The possible race could happen in case new signal from the same group is
      asserted after step (3) and prior step (5). In such case aggregation
      status will change back from 0xff to 0xfd and the value read from the
      aggregation status register will be the same as a value saved in
      aggr_cache. As a result the handler will not traverse down and signal
      will stay unhandled.
      
      Example of faulty flow:
      The signal routing flow is as following (f.e. for of FANi removing):
       - FAN status and event registers related bit is changed;
       -- intermediate aggregation status register is changed;
       --- top aggregation status register is changed;
       ---- interrupt routed to CPU and interrupt handler is invoked.
      
      When interrupt handler is invoked it follows the next simple logic (f.e
      FAN3 is removed):
       (a1) mask top aggregation interrupt mask register;
       (a2) read top aggregation interrupt status register and test to which
            underling group belongs a signal (FANs in this case and is changed
      	  from 0xff to 0xfb and 0xfb is saved as a last status value);
         (b1) mask FANs interrupt mask register;
         (b2) read FANs status register and test which FAN has been changed
              FAN3 in this example);
           (c1) perform relevant action;
                    <--------------- (FAN2 is removed at this point)
         (b3) clear FANs interrupt event register to acknowledge FAN3 signal;
         (b4) unmask FANs interrupt mask register
       (a3) unmask top aggregation interrupt mask register;
      
       An interrupt handler is invoked, since FAN2 interrupt is not acknowledge.
       It should set top aggregation interrupt status register bit 6 (0xfb).
       In step (a2)
       (a2) read top aggregation interrupt and comparing it with saved value
            does not show change (same 0xfb) and after (a2) execution jumps to
      	  (a3) and signal leaved unhandled
      
      The fix will enforce handler to traverse down in case the signal is
      received, but signal assertion is not detected.

      This commit adds the necessary device-properties to make the touchscreen
      on Point of View mobii TAB-P800W (v2.0) tablets work.
      
      Note that we already have an entry for the Point of View mobii
      TAB-P800W (v2.1), that version uses a different digitizer and different
      firmware, so the v2.0 version needs its own entry.

      Do not perform the rfkill cleanup routine when
      (asus->driver->wlan_ctrl_by_user && ashs_present()) is true, since
      nothing is registered with the rfkill subsystem in that case. Doing so
      leads to the following kernel NULL pointer dereference:

      Right now it's possible to set dell laptop to compile in but this
      causes dell-smbios to compile in which breaks if dcdbas is a module.
      
      Dell laptop shouldn't select dell-smbios anymore, but depend on it.

      When the module is removed the led workqueue is destroyed in the remove
      callback, before the led device is unregistered from the led subsystem.
      
      This leads to a NULL pointer derefence when the led device is
      unregistered automatically later as part of the module removal cleanup.
      Bellow is the backtrace showing the problem.

      the OEM string "Dell System" but instead supported www.dell.com
      in OEM strings.
      
      Match both of these to indicate that this driver is running on

      platform: x86: intel_scu_ipc: Replace mdelay with usleep_range in intel_scu_ipc_i2c_cntrl · 8fddfb39
      Jia-Ju Bai authored
      intel_scu_ipc_i2c_cntrl() calls mutex_lock(), which indicates
      this function is not called in atomic context.
      
      Despite never getting called from atomic context,
      intel_scu_ipc_i2c_cntrl() calls mdelay to busily wait.
      This is not necessary and can be replaced with usleep_range to
      avoid busy waiting.
      
      This is found by a static analysis tool named DCNS written by myself.
      And I also manually check it.

           the reduced bit information with the original value.
      
         - Dominiks syscall rework which consolidates the architecture
           specific syscall functions so all syscalls can be wrapped with the
           same macros. This allows to switch x86/64 to struct pt_regs based

      Pull irq affinity fixes from Thomas Gleixner:
      
        - Fix error path handling in the affinity spreading code
      
        - Make affinity spreading smarter to avoid issues on systems which
          claim to have hotpluggable CPUs while in fact they can't hotplug
          anything.
      
          So instead of trying to spread the vectors (and thereby the
          associated device queues) to all possibe CPUs, spread them on all
          present CPUs first. If there are left over vectors after that first
          step they are spread among the possible, but not present CPUs which
          keeps the code backwards compatible for virtual decives and NVME
          which allocate a queue per possible CPU, but makes the spreading
          smarter for devices which have less queues than possible or present
          CPUs.
      
      * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
        genirq/affinity: Spread irq vectors among present CPUs as far as possible
        genirq/affinity: Allow irq spreading from a given starting point
        genirq/affinity: Move actual irq vector spreading into a helper function
        genirq/affinity: Rename *node_to_possible_cpumask as *node_to_cpumask
        genirq/affinity: Don't return with empty affinity masks on error

       - Fix crashes when loading modules built with a different
         CONFIG_RELOCATABLE value by adding CONFIG_RELOCATABLE to vermagic.
      
       - Fix busy loops in the OPAL NVRAM driver if we get certain error
         conditions from firmware.
      
       - Remove tlbie trace points from KVM code that's called in real mode,
         because it causes crashes.
      
       - Fix checkstops caused by invalid tlbiel on Power9 Radix.
      
       - Ensure the set of CPU features we "know" are always enabled is
         actually the minimal set when we build with support for firmware
         supplied CPU features.
