      pidns: fix vfork() after unshare(CLONE_NEWPID) · e79f525e
      Oleg Nesterov authored
      Commit 8382fcac ("pidns: Outlaw thread creation after
      unshare(CLONE_NEWPID)") nacks CLONE_VM if the forking process unshared
      pid_ns, this obviously breaks vfork:
      
      	int main(void)
      	{
      		assert(unshare(CLONE_NEWUSER | CLONE_NEWPID) == 0);
      		assert(vfork() >= 0);
      		_exit(0);
      		return 0;
      	}
      
      fails without this patch.
      
      Change this check to use CLONE_SIGHAND instead.  This also forbids
      CLONE_THREAD automatically, and this is what the comment implies.
      
      We could probably even drop CLONE_SIGHAND and use CLONE_THREAD, but it
      would be safer to not do this.  The current check denies CLONE_SIGHAND
      implicitely and there is no reason to change this.
      
      Eric said "CLONE_SIGHAND is fine.  CLONE_THREAD would be even better.
      Having shared signal handling between two different pid namespaces is
      the case that we are fundamentally guarding against."

      Pull Xen bug-fixes from Konrad Rzeszutek Wilk:
       "This pull I usually do after rc1 is out but because we have a nice
        amount of fixes, some bootup related fixes for ARM, and it is early in
        the cycle we figured to do it now to help with tracking of potential
        regressions.
      
        The simple ones are the ARM ones - one of the patches fell through the
        cracks, other fixes a bootup issue (unconditionally using Xen
        functions).  Then a fix for a regression causing preempt count being
        off (patch causing this went in v3.12).
      
        Lastly are the fixes to make Xen PVHVM guests use PV ticketlocks (Xen
        PV already does).
      
        The enablement of that was supposed to be part of the x86 spinlock
        merge in commit 816434ec ("The biggest change here are
        paravirtualized ticket spinlocks (PV spinlocks), which bring a nice
        speedup on various benchmarks...") but unfortunatly it would cause
        hang when booting Xen PVHVM guests.  Yours truly got all of the bugs
        fixed last week and they (six of them) are included in this pull.
      
        Bug-fixes:
         - Boot on ARM without using Xen unconditionally
         - On Xen ARM don't run cpuidle/cpufreq
         - Fix regression in balloon driver, preempt count warnings
         - Fixes to make PVHVM able to use pv ticketlock.
         - Revert Xen PVHVM disabling pv ticketlock (aka, re-enable pv ticketlocks)"

      powerpc: Default arch idle could cede processor on pseries · 363edbe2
      Vaidyanathan Srinivasan authored
      When adding cpuidle support to pSeries, we introduced two
      regressions:
      
        - The new cpuidle backend driver only works under hypervisors
          supporting the "SLPLAR" option, which isn't the case of the
          old POWER4 hypervisor and the HV "light" used on js2x blades
      
        - The cpuidle driver registers fairly late, meaning that for
          a significant portion of the boot process, we end up having
          all threads spinning. This slows down the boot process and
          increases the overall resource usage if the hypervisor has
          shared processors.
      
      This fixes both by implementing a "default" idle that will cede
      to the hypervisor when possible, in a very simple way without
      all the bells and whisles of cpuidle.

      vfs: make sure we don't have a stale root path if unlazy_walk() fails · d0d27277
      Linus Torvalds authored
      When I moved the RCU walk termination into unlazy_walk(), I didn't copy
      quite all of it: for the successful RCU termination we properly add the
      necessary reference counts to our temporary copy of the root path, but
      for the failure case we need to make sure that any temporary root path
      information is cleared out (since it does _not_ have the proper
      reference counts from the RCU lookup).
      
      We could clean up this mess by just always dropping the temporary root
      information, but Al points out that that would mean that a single lookup
      through symlinks could see multiple different root entries if it races
      with another thread doing chroot.  Not that I think we should really
      care (we had that before too, back before we had a copy of the root path
      in the nameidata).
      
      Al says he has a cunning plan.  In the meantime, this is the minimal fix
      for the problem, even if it's not all that pretty.

      - Early stolen mem reservation from Jesse in x86 boot code. Acked by Ingo
        and hpa.  This was ready much earlier but somehow I've thought it'd go
        in through x86 trees, hence why this is late. Avoids the pci resource
        code to plant mmiobars in the middle of stolen mem and other ugliness.
      - vgaarb improvements from Alex Williamson plus the fix from Ville for the
        vgacon->fbcon smooth transition "feature".
      - Render pageflips on ivb/hsw to avoid stalls due to the ring switching
        when only flipping on the blitter (Chris).
      - Deadlock fixes around our flush_workqueue which crept back in - lockdep
        isn't clever enough :(
      - Shrinker recursion fix from Chris - this is the thing that blew the vma
        patches from Ben I've taken out of 3.12.
      - Fixup for the relocation refactoring. Also an igt testcase to make sure
        we don't break this again.
      - Pile of smaller fixups all over, shortlog has full details.

      dmaengine: dma_sync_wait and dma_find_channel undefined · 4a43f394
      Jon Mason authored
      dma_sync_wait and dma_find_channel are declared regardless of whether
      CONFIG_DMA_ENGINE is enabled, but calling the function without
      CONFIG_DMA_ENGINE enabled results "undefined reference" errors.
      
      To get around this, declare dma_sync_wait and dma_find_channel as inline
      functions if CONFIG_DMA_ENGINE is undefined.
