Merge branch 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull scheduler fixes from Ingo Molnar:
 "Two smaller fixes - plus a context tracking tracing fix that is a bit
  bigger"

* 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  tracing/context-tracking: Add preempt_schedule_context() for tracing
  sched: Fix clear NOHZ_BALANCE_KICK
  sched/x86: Construct all sibling maps if smt
ARM: picoxcell: remove .nr_irqs reference

A recent cleanup caused build errors in some configurations
because the header defining NR_IRQS_LEGACY is not included
here. Since that value is the default, we can just as well
leave it out.

drm/radeon: update lockup tracking when scheduling in empty ring

There might be issue with lockup detection when scheduling on an
empty ring that have been sitting idle for a while. Thus update
the lockup tracking data when scheduling new work in an empty ring.

From Tony Lindgren:

Move OMAP Mailbox framework to drivers via Suman Anna <s-anna@ti.com>

The OMAP Mailbox driver framework is moved out of arch/arm folder
into drivers/mailbox folder, to re-enable building it and also serve
as a baseline for adapting to the new mailbox driver framework. The
changes mainly contain:
  - a minor bug fix and cleanup of mach-specific mailbox code
  - remove any header dependencies from plat-omap for multi-platform
    support
  - represent mailbox device data through platform data/hwmod attrs
  - move the omap mailbox code out of plat-omap/mach-omapX to
    drivers/mailbox folder

KVM: s390: Privileged operation check for TPROT

TPROT is a privileged instruction and thus should generate a privileged

KVM: s390: Privileged operation checks moved to instruction handlers

We need more fine-grained control about the point in time when we check
for privileged instructions, since the exceptions that can happen during
an instruction have a well-defined priority. For example, for the PFMF
instruction, the check for PGM_PRIVILEGED_OP must happen after the check
for PGM_OPERATION since the latter has a higher precedence - thus the
check for privileged operation must not be done in kvm_s390_handle_b9()
already.
