Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next

2014-06-03T21:00:15+00:00

Pull scheduler updates from Ingo Molnar:
 "The main scheduling related changes in this cycle were:

   - various sched/numa updates, for better performance

   - tree wide cleanup of open coded nice levels

   - nohz fix related to rq->nr_running use

   - cpuidle changes and continued consolidation to improve the
     kernel/sched/idle.c high level idle scheduling logic.  As part of
     this effort I pulled cpuidle driver changes from Rafael as well.

   - standardized idle polling amongst architectures

   - continued work on preparing better power/energy aware scheduling

   - sched/rt updates

   - misc fixlets and cleanups"

staging: android: binder.c: Use more appropriate functions for euid retrieval

2014-06-01T18:36:47+00:00

Instead of getting the reference to whole credential structure, use
task_euid() and current_euid() to get it.

staging: binder: fix usage of uninit scalar in binder_transaction()

2014-05-23T11:51:32+00:00

Fix the error path when a cookie mismatch is detected. In that case the
function jumps to the exit label without setting the uninitialized, local
variable 'return_error'. Detected by Coverity - CID 201453.

staging: binder: Support concurrent 32 bit and 64 bit processes.

2014-02-25T00:29:40+00:00

For 64bit systems we want to use the same binder interface for 32bit and
64bit processes. Thus the size and the layout of the structures passed
between the kernel and the userspace has to be the same for both 32 and
64bit processes.

This change replaces all the uses of void* and size_t with
binder_uintptr_t and binder_size_t. These are then typedefed to specific
sizes depending on the use of the interface, as follows:
       * __u32 - on legacy 32bit only userspace
       * __u64 - on mixed 32/64bit userspace where all processes use the same
interface.

This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and
hooks the compat_ioctl entry for the mixed 32/64bit Android userspace.

This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for
compatability, which if set which enables the old protocol, setting
BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems.

Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: binder: Fix death notifications

2014-02-21T20:30:54+00:00

The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the
node release code to a separate function broke death notifications in
some cases. When it encountered a reference without a death
notification request, it would skip looking at the remaining
references, and therefore fail to send death notifications for them.
