      watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing · deb9197b
      Wim Van Sebroeck authored
      Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver
      Jiri Slaby: 28d41f53 broke temperature sensors on a ICH10 chipset
      
      The iTCO_wdt driver disables the SMI. This breaks good working of newer hardware.
      The disabling of the SMI by the TCO logic dates back from the i810-tco driver
      from Nils Faerber (around 28 July 2000). The reason for this was that some BIOSes
      install handlers reset or disable the watchdog timer instead of resetting the system.
      The trick to fix this was to disable the SMI (by clearing the SMI_TCO_EN bit of the
      SMI_EN register) to prevent this from happening.
      
      This however has strange effects on newer hardware. So we are in a situation that
      a fix for broken old hardware affects newer hardware.
      
      The correct solution is to make this fix an option (with the new module parameter:
      turn_SMI_watchdog_clear_off) so that the default behaviour is the unfixed version.
      
      the next patch will be to move this in the start and stop functions of the driver
      and to add a new module parameter for the global_smi_en bit and to get rid of the
      vendor_support code.
      
      This fix can have an effect on old (typical ICH & ICH2 chipsets) motherboards that
      have a broken BIOS implementation concerning TCO logic. In these case the module
      parameter turn_SMI_watchdog_clear_off=1 will need to be added.

      watchdog: Octeon: Mark octeon_wdt interrupt as IRQF_NO_THREAD · 47bfd058
      Venkat Subbiah authored
      This is to exclude it from force threading to allow RT patch set to work.
      
      The watchdog timers are per-CPU and the addresses of register that reset
      the timer are calculated based on the current CPU.  Therefore we cannot
      allow it to run on a thread on a different CPU.  Also we only do a
      single register write, which is much faster than scheduling a handler
      thread.
      
      And while on this line remove IRQF_DISABLED as this flag is a NOP.

      VFS: fix statfs() automounter semantics regression · 5c8a0fbb
      Dan McGee authored
      No one in their right mind would expect statfs() to not work on a
      automounter managed mount point. Fix it.
      
      [ I'm not sure about the "no one in their right mind" part.  It's not
        mounted, and you didn't ask for it to be mounted.  But nobody will
        really care, and this probably makes it match previous semantics, so..
