FWIW, this is not a "resend" - there's at least a commit message
difference here so this should have been v3. Also your cover letter
was not the one generated for the patches you actually sent since
it still mentions "riscv64" in the subject line for patch 5.

That said, this does not apply to riscv/for-next:

  [PATCH v2 1/5] RISC-V: use __smp_processor_id() instead of smp_processor_id()
  [PATCH v2 2/5] RISC-V: Add arch_crash_save_vmcoreinfo support
  [PATCH v2 3/5] riscv: Add modules to virtual kernel memory layout dump
  [PATCH v2 4/5] RISC-V: Fixup getting correct current pc
  [PATCH v2 5/5] riscv: crash_core: Export kernel vm layout, phys_ram_base

Applying: RISC-V: use __smp_processor_id() instead of smp_processor_id()
Applying: RISC-V: Add arch_crash_save_vmcoreinfo support
Patch failed at 0002 RISC-V: Add arch_crash_save_vmcoreinfo support

When you fix that, could you also pick either "riscv" or "RISC-V" as a
prefix the series?

Thanks,
Conor.
