+Subject: [PATCH] arch/arm/boot/compressed: set default Asm architecture to armv7-a
+
+This enables building compressed kernel with newer binutils-2.22 when kernel is
+built in Thumb2 mode. Otherwise it fails with the following Assembler error:
+
+| arch/arm/boot/compressed/head.S: Assembler messages:
+| arch/arm/boot/compressed/head.S:127: Error: selected processor does not support requested special purpose register -- `mrs r2,cpsr'
+| arch/arm/boot/compressed/head.S:134: Error: selected processor does not support requested special purpose register -- `mrs r2,cpsr'
+| arch/arm/boot/compressed/head.S:136: Error: selected processor does not support requested special purpose register -- `msr cpsr_c,r2'
+| make[2]: *** [arch/arm/boot/compressed/head.o] Error 1
+| make[1]: *** [arch/arm/boot/compressed/vmlinux] Error 2
