Subject: [PATCHv2 0/3] Binder ABI updates for 64bit systems for staging-next

Again, wanted to re-submit to staging-next two changes from
the AOSP common.git android-3.10 branch, which provide ABI
fixes and introduce a new ABI and protocol version for binder,
along with compatibility support for existing systems.

This new ABI allows for both 32bit and 64bit applications
to co-exist, which wasn't previously possible due to word
size assumptions in the binder protocol.

Also included is a minor tweak from me to make the Kconfig
compatibility entry a bit more clear.

The changes have been updated to improve their commit message
since the last time they were submitted. Thanks to Arve for the
extra context and Serban for help with the wording.

v2:
* Further tweak commit message to make it more clear the binder
  protocol version is increased only when the
  CONFIG_ANDROID_BINDER_IPC_32BIT option is disabled.

thanks
-john
