linux内核编译过错

穿插编译器：arm-linux-gcc 4.3.3

过错：

arch/arm/mm/alignment.c: In function proc_alignment_write:
arch/arm/mm/alignment.c:119: error: read-only variable __r2 used as asm output
arch/arm/mm/alignment.c:119: error: read-only variable __r2 used as asm output
arch/arm/mm/alignment.c:119: error: read-only variable __r2 used as asm output
arch/arm/mm/alignment.c:119: error: read-only variable __r2 used as asm output
make[1]: *** [arch/arm/mm/alignment.o] 过错 1
make: *** [arch/arm/mm] 过错 2

解决办法：挑选较低版别的穿插编译器，比方3.4.1。
