2.6.32-longterm review patch. If anyone has any objections, please let me know. ------------------ From: Ian Abbott <abbotti@xxxxxxxxx> commit b655c2c4782ed3e2e71d2608154e295a3e860311 upstream. `s626_enc_insn_config()` is incorrectly dereferencing `insn->data` which is a pointer to user memory. It should be dereferencing the separate `data` parameter that points to a copy of the data in kernel memory.
