Lockdep is needed by proving the spinlocks and rwlocks. To suupport
it, we need fixup TRACE_IRQFLAGS_SUPPORT in kernel/entry.S. This
patch follow Documentation/irqflags-tracing.txt.

And there are 2 bugs block the lockdep implementation.

Guo Ren (2):
  riscv: Fixup static_obj() fail
  riscv: Enable LOCKDEP_SUPPORT & fixup TRACE_IRQFLAGS_SUPPORT

Zong Li (1):
  riscv: Fixup lockdep_assert_held with wrong param cpu_running
