/*
 * 10.1:
 * - Do mmap in kernel for SAME_VA memory allocations rather then
 *   calling back into the kernel as a 2nd stage of the allocation request.
 *
 * 10.2:
 * - Add KBASE_FUNC_MEM_JIT_INIT which allows clients to request a custom VA
 *   region for use with JIT (ignored on 32-bit platforms)
 *
 * 10.3:
 * - base_jd_core_req typedef-ed to u32 (instead of to u16)
 * - two flags added: BASE_JD_REQ_SKIP_CACHE_STAT / _END
 *
 * 10.4:
 * - Removed KBASE_FUNC_EXT_BUFFER_LOCK used only in internal tests
 *
 * 10.5:
 * - Reverted to performing mmap in user space so that tools like valgrind work.
 *
 * 10.6:
 * - Add flags input variable to KBASE_FUNC_TLSTREAM_ACQUIRE
