I guess what you meant was this commit:
commit 0a5bee05fc67ce2044b8d91a18abbf14042da531

The modification in Makefile was

-endif
-
-KBUILD_AFLAGS += -march=$(KBUILD_MARCH)$(KBUILD_ARCH_A)fd$(KBUILD_ARCH_C)
+# ISA string setting
+riscv-march-$(CONFIG_ARCH_RV32I)       := rv32im
+riscv-march-$(CONFIG_ARCH_RV64I)       := rv64im
+riscv-march-$(CONFIG_RISCV_ISA_A)      := $(riscv-march-y)a
+riscv-march-y                          := fd
+riscv-march-$(CONFIG_RISCV_ISA_C)      := $(riscv-march-y)c

and the ":= fd" line was wrong.  It should have been 

+riscv-march-y                          := $(riscv-march-y)fd

So I sent the v8 to fix this problem.
Sorry for the inconvinience.

And Palmer, it seems that the patch that causes this build error has been
pulled into linux-next.  Any idea how to fix that one?

Many thanks,
