Merge branch 'core-smp-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull core SMP updates from Ingo Molnar:
"Two main change is generic vCPU pinning and physical CPU SMP-call
support, for Xen to be able to perform certain calls on specific
physical CPUs - by Juergen Gross"
* 'core-smp-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
smp: Allocate smp_call_on_cpu() workqueue on stack too
hwmon: Use smp_call_on_cpu() for dell-smm i8k
dcdbas: Make use of smp_call_on_cpu()
xen: Add xen_pin_vcpu() to support calling functions on a dedicated pCPU
smp: Add function to execute a function synchronously on a CPU
virt, sched: Add generic vCPU pinning support
xen: Sync xen header
