      toshiba_acpi: Change *available functions return type · ea215a3f
      Azael Avalos authored
      This patch changes the *available functions return type from int to
      void.
      
      The checks for support of their respective features are done inside
      such functions and there was no need to return anything as we can
      flag the queried feature as supported inside these functions.
      
      The code was adapted accordingly to these changes and two new
      variables were created and another was changed from uint to bool.
      
      Also, the function toshiba_acceleremoter_supported was renamed to
      toshiba_accelerometer_available to maintain the naming consistency on
      the driver.

      toshiba_acpi: Add set_fan_status function · 3e07e5ba
      Azael Avalos authored
      This patch adds a new function named "set_fan_status" to complement
      its get* counterpart, as well as to avoid code duplication between
      "fan_proc_write" and "fan_store".
      
      Also, both functions (get*, set*) are now checking for TOS_FAILURE,
      TOS_NOT_SUPPORTED and TOS_SUCCESS (to be on par with the rest of the
      HCI/SCI functions), printing an error message, returning -ENODEV and
      zero respectively.
      
      The proc and sysfs functions were updated to reflect these changes as
      well, returning -EIO for proc, and propagating the error value on the
      sysfs functions.

       "Two families of fixes:
      
         - Fix an FPU context related boot crash on newer x86 hardware with
           larger context sizes than what most people test.  To fix this
           without ugly kludges or extensive reverts we had to touch core task
           allocator, to allow x86 to determine the task size dynamically, at
           boot time.
      
           I've tested it on a number of x86 platforms, and I cross-built it
           to a handful of architectures:
      
                                              (warns)               (warns)

             testing     x86-32:  -git:  pass (    0),  -tip:  pass (    0)

      x86/fpu, sched: Dynamically allocate 'struct fpu' · 0c8c0f03
      Dave Hansen authored
      The FPU rewrite removed the dynamic allocations of 'struct fpu'.
      But, this potentially wastes massive amounts of memory (2k per
      task on systems that do not have AVX-512 for instance).
      
      Instead of having a separate slab, this patch just appends the
      space that we need to the 'task_struct' which we dynamically
      allocate already.  This saves from doing an extra slab
      allocation at fork().
      
      The only real downside here is that we have to stick everything
      and the end of the task_struct.  But, I think the
      BUILD_BUG_ON()s I stuck in there should keep that from being too
      fragile.
