[one small request as I have four armv7-m folks on Cc already:
 could one of you try to fix the warning that I get with every
 single build: "/git/arm-soc/arch/arm/kernel/head-nommu.S: Assembler
messages: /git/arm-soc/arch/arm/kernel/head-nommu.S:167: Warning:
Use of r13 as a source register is deprecated when r15 is the
destination register."]
