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