      misc: lis3lv02d_i2c: Fix regulators getting en-/dis-abled twice on suspend/resume · ac3e0384
      Hans de Goede authored
      When not configured for wakeup lis3lv02d_i2c_suspend() will call
      lis3lv02d_poweroff() even if the device has already been turned off
      by the runtime-suspend handler and if configured for wakeup and
      the device is runtime-suspended at this point then it is not turned
      back on to serve as a wakeup source.
      
      Before commit b1b9f7a4 ("misc: lis3lv02d_i2c: Add missing setting
      of the reg_ctrl callback"), lis3lv02d_poweroff() failed to disable
      the regulators which as a side effect made calling poweroff() twice ok.
      
      Now that poweroff() correctly disables the regulators, doing this twice
      triggers a WARN() in the regulator core:
      
      unbalanced disables for regulator-dummy
      WARNING: CPU: 1 PID: 92 at drivers/regulator/core.c:2999 _regulator_disable
      ...
      
      Fix lis3lv02d_i2c_suspend() to not call poweroff() a second time if
      already runtime-suspended and add a poweron() call when necessary to
      make wakeup work.
      
      lis3lv02d_i2c_resume() has similar issues, with an added weirness that
      it always powers on the device if it is runtime suspended, after which
      the first runtime-resume will call poweron() again, causing the enabled
      count for the regulator to increase by 1 every suspend/resume. These
      unbalanced regulator_enable() calls cause the regulator to never
      be turned off and trigger the following WARN() on driver unbind:
      
      WARNING: CPU: 1 PID: 1724 at drivers/regulator/core.c:2396 _regulator_put
      
      Fix this by making lis3lv02d_i2c_resume() mirror the new suspend().
      
      Fixes: b1b9f7a4 ("misc: lis3lv02d_i2c: Add missing setting of the reg_ctrl callback")

      counter: fix privdata alignment · c83ccdc9
      Nuno Sa authored
      Aligning to the L1 cache does not guarantee the same alignment as
      kmallocing an object [1]. Furthermore, in some platforms, that
      alignment is not sufficient for DMA safety (in case someone wants
      to have a DMA safe buffer in privdata) [2].
      
      Sometime ago, we had the same fixes in IIO.

         - Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if
           and only if the incoming events->nmi.pending is non-zero. If the
           target vCPU is in the UNITIALIZED state, the spurious request will
           result in KVM exiting to userspace, which in turn causes QEMU to
           constantly acquire and release QEMU's global mutex, to the point
           where the BSP is unable to make forward progress.
      
         - Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl
           being incorrectly truncated, and ultimately causes KVM to think a
           fixed counter has already been disabled (KVM thinks the old value
           is '0').
      
         - Fix a stack leak in KVM_GET_MSRS where a failed MSR read from
           userspace that is ultimately ignored due to ignore_msrs=true
           doesn't zero the output as intended.
      
        Selftests cleanups and fixes:
      
         - Remove redundant newlines from error messages.
      
         - Delete an unused variable in the AMX test (which causes build
           failures when compiling with -Werror).
      
         - Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails
           with an error code other than ENOENT (a Hyper-V selftest bug
           resulted in an EMFILE, and the test eventually got skipped).
      
         - Fix TSC related bugs in several Hyper-V selftests.
      
         - Fix a bug in the dirty ring logging test where a sem_post() could
           be left pending across multiple runs, resulting in incorrect
           synchronization between the main thread and the vCPU worker thread.
      
         - Relax the dirty log split test's assertions on 4KiB mappings to fix
           false positives due to the number of mappings for memslot 0 (used
           for code and data that is NOT being dirty logged) changing, e.g.

      Pull tracing fixes from Steven Rostedt:
      
       - Fix the #ifndef that didn't have the 'CONFIG_' prefix on
         HAVE_DYNAMIC_FTRACE_WITH_REGS
      
         The fix to have dynamic trampolines work with x86 broke arm64 as the
         config used in the #ifdef was HAVE_DYNAMIC_FTRACE_WITH_REGS and not
         CONFIG_HAVE_DYNAMIC_FTRACE_WITH_REGS which removed the fix that the
         previous fix was to fix.
      
       - Fix tracing_on state
      
         The code to test if "tracing_on" is set incorrectly used
         ring_buffer_record_is_on() which returns false if the ring buffer
         isn't able to be written to.
      
         But the ring buffer disable has several bits that disable it. One is
         internal disabling which is used for resizing and other modifications
         of the ring buffer. But the "tracing_on" user space visible flag
         should only report if tracing is actually on and not internally
         disabled, as this can cause confusion as writing "1" when it is
         disabled will not enable it.
      
         Instead use ring_buffer_record_is_set_on() which shows the user space
         visible settings.
      
       - Fix a false positive kmemleak on saved cmdlines
      
         Now that the saved_cmdlines structure is allocated via alloc_page()
         and not via kmalloc() it has become invisible to kmemleak. The
         allocation done to one of its pointers was flagged as a dangling
         allocation leak. Make kmemleak aware of this allocation and free.
      
       - Fix synthetic event dynamic strings
      
         An update that cleaned up the synthetic event code removed the return
         value of trace_string(), and had it return zero instead of the
         length, causing dynamic strings in the synthetic event to always have
         zero size.
      
       - Clean up documentation and header files for seq_buf
      
      * tag 'trace-v6.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
        seq_buf: Fix kernel documentation
        seq_buf: Don't use "proxy" headers
        tracing/synthetic: Fix trace_string() return value
        tracing: Inform kmemleak of saved_cmdlines allocation
        tracing: Use ring_buffer_record_is_set_on() in tracer_tracing_is_on()
