nmi_enter()/nmi_exit() touches per cpu variables which can lead to kernel
crash when invoked during real mode interrupt handling (e.g. early HMI/MCE
interrupt handler) if percpu allocation comes from vmalloc area.
Early HMI/MCE handlers are called through DEFINE_INTERRUPT_HANDLER_NMI()

A structure is added called nvdimm_pmu, for performance
stats reporting support of nvdimm devices. It can be used to add
device pmu data such as pmu data structure for performance
stats, nvdimm device pointer along with cpumask attributes.
Acked-by: Peter Zijlstra (Intel)
Tested-by: Nageswara R S
A common interface is added to get performance stats reporting
support for nvdimm devices. Added interface defines supported
event list, config fields for the event attributes and their
corresponding bit values which are exported via sysfs.
Interface also added support for pmu register/unregister
Patchset adds performance stats reporting support for nvdimm.
Added interface includes support for pmu register/unregister
functions. A structure is added called nvdimm_pmu to be used for
adding arch/platform specific data such as cpumask, nvdimm device
pointer and pmu event functions like event_in
Performance monitoring support for papr-scm nvdimm devices
via perf interface is added which includes addition of pmu
functions like add/del/read/event_init for nvdimm_pmu struture.
A new parameter 'priv' in added to the pdev_archdata structure to save
nvdimm_pmu device pointer, to handle the unre
Details are added for the event, cpumask and format attributes
in the ABI documentation.

I've applied patches 1,5,6,8 and 9 to the dma-mapping tree.
Since commit ceff77efa4f8 ("powerpc/64e/interrupt: Use new interrupt
context tracking scheme") struct interrupt_state has been empty and
unused.
Remove it.
