From 777783e0abae3cab7555bb182776f9ffaa35631a Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 16 Oct 2014 14:40:38 +0200 Subject: [PATCH] staging: android: binder: move to the "real" part of the kernel The Android binder code has been "stable" for many years now. No matter what comes in the future, we are going to have to support this API, so might as well move it to the "real" part of the kernel as there's no real work that needs to be done to the existing code.
