Add Early Suspend to CONSERVATIVE
cpufreq: conservative: Fix sampling_down_factor
 functionality

sampling_down_factor tunable is unused since commit
8e677ce83bf41ba9c74e5b6d9ee60b07d4e5ed93 (4 years ago).

This patch restores the original functionality and documents the
tunable.

cpufreq: conservative: Fix the logic in frequency
decrease checking

When we evaluate the CPU load for frequency decrease we have to compare
the load against down_threshold. There is no need to subtract 10 points
from down_threshold.

Instead, we have to use the default down_threshold or user's selection
unmodified.

Logger from 3.8
staging: android: logger: Allow a UID to read it's own log entries

Modify the kernel logger to record the UID associated with
the log entries. Always allow the same UID which generated a
log message to read the log message.

Allow anyone in the logs group, or anyone with CAP_SYSLOG, to
read all log entries.

In addition, allow the client to upgrade log formats, so they
can get additional information from the kernel.
