      hrtimer: Tune hrtimer_interrupt hang logic · 41d2e494
      Thomas Gleixner authored
      The hrtimer_interrupt hang logic adjusts min_delta_ns based on the
      execution time of the hrtimer callbacks.
      
      This is error-prone for virtual machines, where a guest vcpu can be
      scheduled out during the execution of the callbacks (and the callbacks
      themselves can do operations that translate to blocking operations in
      the hypervisor), which in can lead to large min_delta_ns rendering the
      system unusable.
      
      Replace the current heuristics with something more reliable. Allow the
      interrupt code to try 3 times to catch up with the lost time. If that
      fails use the total time spent in the interrupt handler to defer the
      next timer interrupt so the system can catch up with other things
      which got delayed. Limit that deferment to 100ms.
      
      The retry events and the maximum time spent in the interrupt handler
      are recorded and exposed via /proc/timer_list
      
      Inspired by a patch from Marcelo.

      Luis Garces-Erice authored
      the description in Documentation/filesystems/proc.txt of the
      procs_running entry in /proc/stat is confusing (according to that
      description, it looks as if procs_running could only be a number
      between 0 and the number of CPUs).

      nvram: Fix missing smp_lock.h in nvram · 79a56ed0
      Frederic Weisbecker authored
      The bkl has been removed from nvram_llseek() and smp_lock.h was removed
      because another patch in the same tree zapped the remaining usage of bkl
      in the same file.  But this patch must have been excluded later, then we
      still need the smp_lock.h headers for the bkl use in nvram_open().
      
      This fixes the following build error:
      
        drivers/char/nvram.c: In function ‘nvram_open’:

      Jean Delvare authored
      It is possible to bypass the voltage attenuators on the +2.5V, Vccp,
      +5V and +12V voltage monitoring inputs. This is useful to connect
      other voltage channels than the ones the monitoring chip was
      originally designed for. When this feature is enabled, we must not
      include the scaling factors in our computations.

      Move sysfs files removal to a separate function. The code is common to
      the device probing error path and the standard device removal path. As

      hwmon: (f71882fg) Add support for the f71889fg (version 2) · 7669896f
      Hans de Goede authored
      This adds support for the Fintek f71889fg to the f71882fg driver,
      many thanks to Gerd v. Egidy for providing (remote) access to a
      machine which such an ic.
      
      Note that this bit of the patch:
      -	val = SENSORS_LIMIT(val, 0, 255);
      +
      +	if (data->type == f71889fg)
      +		val = SENSORS_LIMIT(val, -128, 127);
      +	else
      +		val = SENSORS_LIMIT(val, 0, 127);
      
      Changes behaviour for already supported models, the new behaviour is correct
      as the already supported models have bit 7 of the involved registers fixed at
      0, so the previous behaviour which allowed setting temp zone limits > 127
      was not correct.

      hwmon: (f71882fg) Fix sysfs file removal · fc16c56e
      Hans de Goede authored
      There is a bug in the old sysfs file removal, as it uses fxxxx_in_temp_attr
      to remove the in and temp sysfs attributes, but fxxxx_in_temp_attr has
      temp#_alarm, where as f71858fg_in_temp_attr has temp#_max_alarm, so
      the temp#_max_alarm attributes for the f71858fg never get removed.
      
      This patch fixes this by doing the sysfs removal exactly the same way as
      the creation instead of being (too) clever, this will also avoid similar
      bugs in the future.
