This patch breaks build:

  CC      riscv32-softmmu/target/riscv/cpu.o
.../qemu/target/riscv/cpu.c: In function 'riscv_isa_string':
.../qemu/target/riscv/cpu.c:378:20: error: implicit declaration of function 
'qemu_tolower'; did you mean 'qemu_irq_lower'? 
[-Werror=implicit-function-declaration]
             *p++ = qemu_tolower(riscv_exts[i]);
                    ^~~~~~~~~~~~
                    qemu_irq_lower
.../qemu/target/riscv/cpu.c:378:20: error: nested extern declaration of 
'qemu_tolower' [-Werror=nested-externs]
cc1: all warnings being treated as errors

I remove the series from the trivial-patches branch.

Thanks,
Laurent
