      cpuidle / ACPI: remove unused CPUIDLE_FLAG_TIME_INVALID · 62c4cf97
      Len Brown authored
      
      
      CPUIDLE_FLAG_TIME_INVALID is no longer checked
      by menu or ladder cpuidle governors, so don't
      bother setting or defining it.
      
      It was originally invented to account for the fact that
      acpi_safe_halt() enables interrupts to invoke HLT.
      That would allow interrupt service routines to be included
      in the last_idle duration measurements made in cpuidle_enter_state(),
      potentially returning a duration much larger than reality.
      
      But menu and ladder can gracefully handle erroneously large duration
      intervals without checking for CPUIDLE_FLAG_TIME_INVALID.
      Further, if they don't check CPUIDLE_FLAG_TIME_INVALID, they
      can also benefit from the instances when the duration interval
      is not erroneously large.

      cpuidle: ladder: Better idle duration measurement without using CPUIDLE_FLAG_TIME_INVALID · b73026b9
      Len Brown authored
      
      
      When the ladder governor sees the CPUIDLE_FLAG_TIME_INVALID flag,
      it unconditionally causes a state promotion by setting last_residency
      to a number higher than the state's promotion_time:
      
      last_residency = last_state->threshold.promotion_time + 1
      
      It does this for fear that cpuidle_get_last_residency()
      will be in-accurate, because cpuidle_enter_state() invoked
      a state with CPUIDLE_FLAG_TIME_INVALID.
      
      But the only state with CPUIDLE_FLAG_TIME_INVALID is
      acpi_safe_halt(), which may return well after its actual
      idle duration because it enables interrupts, so cpuidle_enter_state()
      also measures interrupt service time.
      
      So what?  In ladder, a huge invalid last_residency has exactly
      the same effect as the current code -- it unconditionally
      causes a state promotion.
      
      In the case where the idle residency plus measured interrupt
      handling time is less than the state's demotion_time -- we should
      use that timestamp to give ladder a chance to demote, rather than
      unconditionally promoting.
      
      This can be done by simply ignoring the CPUIDLE_FLAG_TIME_INVALID,
      and using the "invalid" time, as it is either equal to what we are
      doing today, or better.

      cpuidle: menu: Better idle duration measurement without using CPUIDLE_FLAG_TIME_INVALID · 4108b3d9
      Len Brown authored
      
      
      When menu sees CPUIDLE_FLAG_TIME_INVALID, it ignores its timestamps,
      and assumes that idle lasted as long as the time till next predicted
      timer expiration.
      
      But if an interrupt was seen and serviced before that duration,
      it would actually be more accurate to use the measured time
      rather than rounding up to the next predicted timer expiration.
      
      And if an interrupt is seen and serviced such that the mesured time
      exceeds the time till next predicted timer expiration, then
      truncating to that expiration is the right thing to do --
      since we can never stay idle past that timer expiration.
      
      So the code can do a better job without
      checking for CPUIDLE_FLAG_TIME_INVALID.

      kernel: use the gnu89 standard explicitly · 51b97e35
      Kirill A. Shutemov authored
      
      
      Sasha Levin reports:
       "gcc5 changes the default standard to c11, which makes kernel build
        unhappy
      
        Explicitly define the kernel standard to be gnu89 which should keep
        everything working exactly like it was before gcc5"
      
      There are multiple small issues with the new default, but the biggest
      issue seems to be that the old - and very useful - GNU extension to
      allow a cast in front of an initializer has gone away.
      
      Patch updated by Kirill:
       "I'm pretty sure all gcc versions you can build kernel with supports
        -std=gnu89.  cc-option is redunrant.
      
        We also need to adjust HOSTCFLAGS otherwise allmodconfig fails for me"
      
      Note by Andrew Pinski:
       "Yes it was reported and both problems relating to this extension has
        been added to gnu99 and gnu11.  Though there are other issues with the
        kernel dealing with extern inline have different semantics between
        gnu89 and gnu99/11"
      
      End result: we may be able to move up to a newer stdc model eventually,
      but right now the newer models have some annoying deficiencies, so the
      traditional "gnu89" model ends up being the preferred one.

           commit that forgot to check a pointer against NULL before
           dereferencing it (Dmitry Eremin-Solenikov).
      
         - Fix a boot crash on Exynos5 introduced by a recent commit making
           that platform use generic Device Tree bindings for power domains
           which exposed a weakness in the generic power domains framework
           leading to that crash (Ulf Hansson).
      
         - Fix a crash during system resume on systems where cpufreq depends
           on Operation Performance Points (OPP) for functionality, but
           CONFIG_OPP is not set.  This leads the cpufreq driver registration
           to fail, but the resume code attempts to restore the pre-suspend
           cpufreq configuration (which does not exist) nevertheless and
           crashes.  From Geert Uytterhoeven.
      
         - Add a new ACPI blacklist entry for Dell Vostro 3546 that has
           problems if it is reported as Windows 8 compatible to the BIOS
           (Adam Lee).
      
         - Fix swapped arguments in an error message in the cpufreq-dt driver
           (Abhilash Kesavan).
      
         - Fix up the prototypes of new callbacks in struct generic_pm_domain
           to make them more useful.  Users of those callbacks will be added
           in 3.19 and it's better for them to be based on the correct struct
           definition in mainline from the start.  From Ulf Hansson and Kevin
           Hilman"

      firewire: cdev: prevent kernel stack leaking into ioctl arguments · eaca2d8e
      Stefan Richter authored
      
      
      Found by the UC-KLEE tool:  A user could supply less input to
      firewire-cdev ioctls than write- or write/read-type ioctl handlers
      expect.  The handlers used data from uninitialized kernel stack then.
      
      This could partially leak back to the user if the kernel subsequently
      generated fw_cdev_event_'s (to be read from the firewire-cdev fd)
      which notably would contain the _u64 closure field which many of the
      ioctl argument structures contain.
      
      The fact that the handlers would act on random garbage input is a
      lesser issue since all handlers must check their input anyway.
      
      The fix simply always null-initializes the entire ioctl argument buffer
      regardless of the actual length of expected user input.  That is, a
      runtime overhead of memset(..., 40) is added to each firewirew-cdev
      ioctl() call.  [Comment from Clemens Ladisch:  This part of the stack is
      most likely to be already in the cache.]
      
      Remarks:
        - There was never any leak from kernel stack to the ioctl output
          buffer itself.  IOW, it was not possible to read kernel stack by a
          read-type or write/read-type ioctl alone; the leak could at most
          happen in combination with read()ing subsequent event data.
        - The actual expected minimum user input of each ioctl from
          include/uapi/linux/firewire-cdev.h is, in bytes:
          [0x00] = 32, [0x05] =  4, [0x0a] = 16, [0x0f] = 20, [0x14] = 16,
          [0x01] = 36, [0x06] = 20, [0x0b] =  4, [0x10] = 20, [0x15] = 20,
          [0x02] = 20, [0x07] =  4, [0x0c] =  0, [0x11] =  0, [0x16] =  8,
          [0x03] =  4, [0x08] = 24, [0x0d] = 20, [0x12] = 36, [0x17] = 12,
          [0x04] = 20, [0x09] = 24, [0x0e] =  4, [0x13] = 40, [0x18] =  4.
