Adding support for supplied_from char * array. This is meant to store the
list of suppliers for a given supply, i.e. chargers for a battery. This

directly from the driver.

This property is meant to be used in device nodes which represent

v1:
- changed from RFC v2 -> patch v1
- made porop
This patch adds support for supplies to register a list of char *'s
which represent the list of supplies which supply them. This is the
opposite as the supplied_to list.
This change maintains support for supplied_to until all drivers which
make use of it already are converted.
Signed-off-by: Rhyl
This series defines a common way for devicetree initialized
power_supplies to define their relationships between chargers and
supplicants.
This series adds a supplied_from array to complement the supplied_to
array and to allow supplies to define the list of supplies which
supply them.

Well, the argument was that process / thread counts were a poor and
unnecessary proxy for kernel mem

With this patch applied on top of 3.8.5 the bug could not be reproduced
any longer (till now).

of fallbacking to host allocation when On-Chip allocation fails, it
tries to allocate both. And when it does, and we try to free the address

This eliminates the rest of the contention found in __cpufreq_cpu_get.
I am not seeing a way to use the rcu so we will have to make due with a
rwlock for now.

The cpufreq_driver_lock is hot with some configs.
This lock covers both cpufreq_driver and cpufreq_cpu_data, so part one of the
proposed fix is to split up the lock into two pieces.
cpufreq_cpu_data is now covered by the cpufreq_data_lock.
cpufreq_driver is now covered by the cpufreq_driver lock an
I am noticing the cpufreq_driver_lock is quite hot.
On an idle 512 system perf shows me most of the system time is spent on this
lock. This is quite significant as top shows 5% of time in system time.
My solution was to first split the lock into two parts, cpu_driver_lock and
cpu_data_lock, with
