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.

Binder: add TF_UPDATE_TXN to replace outdated txn When the target process is busy, incoming oneway transactions are queued in the async_todo list. If the clients continue sending extra oneway transactions while the target process is frozen, this queue can become too large to accommodate new transactions. That's why binder driver introduced ONEWAY_SPAM_DETECTION to detect this situation. It's helpful to debug the async binder buffer exhausting issue, but the issue itself isn't solved directly. In real cases applications are designed to send oneway transactions repeatedly, delivering updated inforamtion to the target process. Typical examples are Wi-Fi signal strength and some real time sensor data. Even if the apps might only care about the lastet information, all outdated oneway transactions are still accumulated there until the frozen process is thawed later. For this kind of situations, there's no existing method to skip those outdated transactions and deliver the latest one only. This patch introduces a new transaction flag TF_UPDATE_TXN. To use it, use apps can set this new flag along with TF_ONE_WAY. When such an oneway transaction is to be queued into the async_todo list of a frozen process, binder driver will check if any previous pending transactions can be superseded by comparing their code, flags and target node. If such an outdated pending transaction is found, the latest transaction will supersede that outdated one. This effectively prevents the async binder buffer running out and saves unnecessary binder read workloads.
