      powerpc: Fix build warning on 32-bit PPC · 8ae679c4
      Larry Finger authored
      I am getting the following warning when I build kernel 4.9-git on my
      PowerBook G4 with a 32-bit PPC processor:
      
          AS      arch/powerpc/kernel/misc_32.o
        arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef]
      
      This problem is evident after commit 989cea5c ("kbuild: prevent
      lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an
      error that has been in the code since 2005 when this source file was
      created.  That was with commit 9994a338 ("powerpc: Introduce
      entry_{32,64}.S, misc_{32,64}.S, systbl.S").
      
      The offending line does not make a lot of sense.  This error does not
      seem to cause any errors in the executable, thus I am not recommending
      that it be applied to any stable versions.
      
      Thanks to Nicholas Piggin for suggesting this solution.
      
      Fixes: 9994a338 ("powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S")

      avoid spurious "may be used uninitialized" warning · d33d5a6c
      Linus Torvalds authored
      The timer type simplifications caused a new gcc warning:
      
        drivers/base/power/domain.c: In function ‘genpd_runtime_suspend’:
        drivers/base/power/domain.c:562:14: warning: ‘time_start’ may be used uninitialized in this function [-Wmaybe-uninitialized]
           elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start));
      
      despite the actual use of "time_start" not having changed in any way.
      It appears that simply changing the type of ktime_t from a union to a
      plain scalar type made gcc check the use.
      
      The variable wasn't actually used uninitialized, but gcc apparently
      failed to notice that the conditional around the use was exactly the
      same as the conditional around the initialization of that variable.
      
      Add an unnecessary initialization just to shut up the compiler.

      Pull timer type cleanups from Thomas Gleixner:
       "This series does a tree wide cleanup of types related to
        timers/timekeeping.
      
         - Get rid of cycles_t and use a plain u64. The type is not really
           helpful and caused more confusion than clarity
      
         - Get rid of the ktime union. The union has become useless as we use
           the scalar nanoseconds storage unconditionally now. The 32bit
           timespec alike storage got removed due to the Y2038 limitations
           some time ago.
      
           That leaves the odd union access around for no reason. Clean it up.
      
        Both changes have been done with coccinelle and a small amount of
        manual mopping up"

      Pull SMP hotplug notifier removal from Thomas Gleixner:
       "This is the final cleanup of the hotplug notifier infrastructure. The
        series has been reintgrated in the last two days because there came a
        new driver using the old infrastructure via the SCSI tree.
      
        Summary:
      
         - convert the last leftover drivers utilizing notifiers
      
         - fixup for a completely broken hotplug user
      
         - prevent setup of already used states
      
         - removal of the notifiers
      
         - treewide cleanup of hotplug state names
      
         - consolidation of state space
      
        There is a sphinx based documentation pending, but that needs review
        from the documentation folks"
