Currently, leaking_addresses.pl only supports scanning 64 bit
architectures. This is due to how the regular expressions are formed. We
can do better than this. 32 architectures can be supported if we take
into consideration the kernel virtual address split (via the PAGE_OFFSET
kernel configurable).

This patch brings basic support for the Linux Driver Model to the
NuBus subsystem.
For flexibility, the matching of boards with drivers is left up to the
drivers. This is also the approach taken by NetBSD. A board may have
many functions, and drivers may have to consider many functional
resources
This fixes a couple of warnings from 'make W=1':

Perf has a set of static variables to record the runtime shadow

While if we want to record the runtime shadow stats for per-thread,
it will be the limitation. This patch creates a structure and the
next patches will use this structure to update the runtime shadow
stats for per-threa
The functions perf_stat__update_shadow_stats() is called
to update the shadow stats on a set of static variables.
But the static variables are the limitations to be extended
to support per-thread shadow stats.
This patch lets the perf_stat__update_shadow_stats() support
to update the shadow stats
Previously the rbtree was used to link generic metrics.
This patches adds new ctx/type/stat into rbtree keys because we
will use this rbtree to maintain shadow metrics to replace original
a couple of static arrays for supporting per-thread shadow stats.

The function perf_stat__print_shadow_statss() is called
to print the shadow stats on a set of static variables.
But the static variables are the limitations to support
per-thread shadow stats.
This patch lets the perf_stat__print_shadow_stats() support
to print the shadow stats from a input param
In previous patches, we have reconstructed the code and let
it not access the static variables directly.
This patch removes these static variables.

It mainly initializes and releases the rblist which is
defined in struct runtime_stat.
For the original rblist 'runtime_saved_values', it's still
kept there for keeping the patch bisectable.
The rblist 'runtime_saved_values' will be removed in later
patch at switching time.

Update according to Arnaldo's comments.
1. In 'perf util: Define a structure for runtime shadow stats'
Remove '#include "evsel.h"'
2. In 'perf stat: Extend rbtree to support per-thread shadow stats'
Change patch subject to 'perf stat: Extend rbtree to support per-thread shadow
stats'.

There are many threads reported if we enable '--per-thread'
globally.
1. Most of the threads are not counted or counting value 0.
This patch removes these threads.
2. We also resort the threads in display according to the
counting value. It's useful for user to see the hottest
threads easily.

If the stats pointer in stat_config structure is not null, it will

Currently, if we execute 'perf stat --per-thread' without specifying
pid/tid, perf will return error.
root@skl:/tmp# perf stat --per-thread
The --per-thread option is only available when monitoring via -p -t options.
-p, --pidstat events on existing process id
-t, --tidstat
After perf_evlist__create_maps() being executed, we can get all
threads from /proc. And via thread_map__nr(), we can also get
the number of threads.
With the number of threads, the patch allocates a buffer which
will record the shadow stats for these threads.
The buffer pointer is saved in stat_c

To be compatible with legacy device, reset the addressing mode
to the default mode. Such as Freescale eSPI boot, it copies the
images from SPI flash without firing a reset signal previously,
so the reboot command will fail without reseting the addressing
mode of SPI flash.

of_cpufreq_cooling_register() isn't used by anyone and so can be
removed, but then we would be left with two routines:
cpufreq_cooling_register() and of_cpufreq_power_cooling_register() that
would look odd.
Remove current implementation of of_cpufreq_cooling_register() and
rename of_cpufreq_power_
All the callers of of_cpufreq_power_cooling_register() have almost
identical code and it makes more sense to move that code into the helper
as its all about reading DT properties.
This got rid of lot of redundant code.

Hi,
This cleans up the helpers exposed by cpu_cooling driver and its users
and removes a lot of code (around 280 lines effectively). Lots of unused
code is removed.
Tested on Hikey6220 and based over pm/linux-next.
V1->V2:
- Fixed a compilation warning when CONFIG_CPU_THERMAL isn't selected.
