This patchset enables Nest Instrumentation support on powerpc.
POWER8 has per-chip Nest Intrumentation which provides various
per-chip metrics like memory, powerbus, Xlink and Alink
bandwidth.
Nest Instrumentation provides an interface (via PORE Engine)
to configure and move the nest counter data
Nest Counters can be configured via PORE Engine and OPAL
provides an interface to start/stop it.
OPAL side patches are posted in the skiboot mailing.

Parse device tree to detect supported nest pmu units. Traverse
through each nest pmu unit folder to find supported events and
corresponding unit/scale files (if any).
The nest unit event file from Device Tree will contain the offset in the

For Nest pmu, device tree will have
Adds cpumask attribute to be used by each nest pmu since nest
units are per-chip. Only one cpu (first online cpu) from each chip
is designated to read counters.
On cpu hotplug, dying cpu is checked to see whether it is one of the
designated cpus, if yes, next online cpu from the same chip is

Bytes alignment is required to manage some special RAM,
so add gen_pool_first_fit_align to genalloc,
meanwhile add gen_pool_alloc_data to pass data to
gen_pool_first_fit_align(modify gen_pool_alloc as a wrapper)
