From: Guo Ren <[email protected]> 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 arch/riscv/Kconfig | 3 +++ arch/riscv/kernel/entry.S | 41 ++++++++++++++++++++++++++++++++++++++++- arch/riscv/kernel/smpboot.c | 1 - arch/riscv/kernel/vmlinux.lds.S | 2 +- 4 files changed, 44 insertions(+), 3 deletions(-) -- 2.7.4
