      tracefs: Add new tracefs file system · 4282d606
      Steven Rostedt (Red Hat) authored
      
      Add a separate file system to handle the tracing directory. Currently it
      is part of debugfs, but that is starting to show its limits.
      
      One thing is that in order to access the tracing infrastructure, you need
      to mount debugfs. As that includes debugging from all sorts of sub systems
      in the kernel, it is not considered advisable to mount such an all
      encompassing debugging system.
      
      Having the tracing system in its own file systems gives access to the
      tracing sub system without needing to include all other systems.
      
      Another problem with tracing using the debugfs system is that the
      instances use mkdir to create sub buffers. debugfs does not support mkdir
      from userspace so to implement it, special hacks were used. By controlling
      the file system that the tracing infrastructure uses, this can be properly
      done without hacks.

      tracing: Create cmdline tracer options on tracing fs init · 09d23a1d
      Steven Rostedt (Red Hat) authored
      
      The options for cmdline tracers are not created if the debugfs system
      is not ready yet. If tracing has started before debugfs is up, then the
      option files for the tracer are not created. Create them when creating
      the tracing directory if the current tracer requires option files.

      tracing: Only create tracer options files if directory exists · 0f67f04f
      Steven Rostedt (Red Hat) authored
      
      Do not bother creating tracer options if no tracing directory
      exists. If a tracer is enabled via the command line, and is
      started before the tracing directory is created, then it wont have
      its tracer specific options created.

       "We've been sitting on our fixes branch for a while, so this batch is
        unfortunately on the large side.
      
        A lot of these are tweaks and fixes to device trees, fixing various
        bugs around clocks, reg ranges, etc.  There's also a few defconfig
        updates (which are on the late side, no more of those).
      
        All in all the diffstat is bigger than ideal at this time, but nothing
        in here seems particularly risky"

      Kevin Hao authored
      
      This reverts commit da788acb.
      
      That commit tried to fix the section mismatch warning by moving the
      ppc_corenet_clk_driver struct to init section. This is definitely wrong
      because the kernel would free the memories occupied by this struct
      after boot while this driver is still registered in the driver core.
      The kernel would panic when accessing this driver struct.

      clk: rockchip: fix deadlock possibility in cpuclk · a5e1baf7

      Lockdep reported a possible deadlock between the cpuclk lock and for example
      the i2c driver.
      
             CPU0                    CPU1
             ----                    ----
        lock(clk_lock);
                                     local_irq_disable();
                                     lock(&(&i2c->lock)->rlock);
                                     lock(clk_lock);
        <Interrupt>
          lock(&(&i2c->lock)->rlock);
      
       *** DEADLOCK ***
      
      The generic clock-types of the core ccf already use spin_lock_irqsave when
      touching clock registers, so do the same for the cpuclk.
