Jeff Vander Stoep 377fd8e3af ANDROID: restrict access to perf events
Add:
CONFIG_SECURITY_PERF_EVENTS_RESTRICT=y

to android-base.cfg

The kernel.perf_event_paranoid sysctl is set to 3 by default.
No unprivileged use of the perf_event_open syscall will be
permitted unless it is changed.

The files in this directory are meant to be used as a base for an Android
kernel config. All devices should have the options in android-base.cfg enabled.
While not mandatory, the options in android-recommended.cfg enable advanced
Android features.

Assuming you already have a minimalist defconfig for your device, a possible
way to enable these options would be:

     ARCH=<arch> scripts/kconfig/merge_config.sh <path_to>/<device>_defconfig android/configs/android-base.cfg android/configs/android-recommended.cfg

This will generate a .config that can then be used to save a new defconfig or
compile a new kernel with Android features enabled.

Because there is no tool to consistently generate these config fragments,
lets keep them alphabetically sorted instead of random.
