[PATCH 00/10] android: binder: support for domains and scatter-gather.

[Martijn Coenen]

Android userspace will start using binder IPC for communication with HAL
modules. To clearly separate this IPC domain from the existing framework
IPC domain, this patch series adds support for multiple "binder domains".
This is implemented by each domain having its own binder context manager,
and then having a separate device node per domain.

The other change introduced by this series is scatter-gather; currently
all objects passed through binder IPC must be serialized in userspace, with
with the exception of binder objects and file descriptors. By adding scatter-
gather support for memory buffers, we can avoid the serialization copy,
thereby increasing performance for larger transaction sizes.

The two patches from Arve are security patches that we've already applied
in android-common. I included them in front of the series because my changes
touch quite some of that code.

Arve HjÃnnevÃg (2):
  ANDROID: binder: Add strong ref checks
  ANDROID: binder: Clear binder and cookie when setting handle in flat
    binder struct

Martijn Coenen (8):
  android: binder: split flat_binder_object.
  android: binder: support multiple context managers.
  android: binder: deal with contexts in debugfs.
  android: binder: support multiple /dev instances.
  android: binder: refactor binder_transact()
  android: binder: add extra size to allocator.
  android: binder: support for scatter-gather.
  android: binder: support for file-descriptor arrays.
