+Subject: [PATCH] riscv: Fix build against binutils 2.38
+
+The following description is copied from the equivalent patch for the
+Linux Kernel proposed by Aurelien Jarno:
+
+>From version 2.38, binutils default to ISA spec version 20191213. This
+means that the csr read/write (csrr*/csrw*) instructions and fence.i
+instruction has separated from the `I` extension, become two standalone
+extensions: Zicsr and Zifencei. As the kernel uses those instruction,
+this causes the following build failure:
+
+arch/riscv/cpu/mtrap.S: Assembler messages:
+arch/riscv/cpu/mtrap.S:65: Error: unrecognized opcode `csrr a0,scause'
+arch/riscv/cpu/mtrap.S:66: Error: unrecognized opcode `csrr a1,sepc'
+arch/riscv/cpu/mtrap.S:67: Error: unrecognized opcode `csrr a2,stval'
+arch/riscv/cpu/mtrap.S:70: Error: unrecognized opcode `csrw sepc,a0'
