Merge commit 'v2.6.36' into wip-merge-2.6.36
Conflicts: Makefile arch/x86/include/asm/unistd_32.h arch/x86/kernel/syscall_table_32.S kernel/sched.c kernel/time/tick-sched.c Relevant API and functions changes (solved in this commit): - (API) .enqueue_task() (enqueue_task_litmus), dequeue_task() (dequeue_task_litmus), [litmus/sched_litmus.c] - (API) .select_task_rq() (select_task_rq_litmus) [litmus/sched_litmus.c] - (API) sysrq_dump_trace_buffer() and sysrq_handle_kill_rt_tasks() [litmus/sched_trace.c] - struct kfifo internal buffer name changed (buffer -> buf) [litmus/sched_trace.c] - add_wait_queue_exclusive_locked -> __add_wait_queue_tail_exclusive [litmus/fmlp.c] - syscall numbers for both x86_32 and x86_64
