config warnings while selecting u300_defconfig

[devendra.aaru]

Hi,

While doing compiling for u300, i selected the u300_defconfig,

make ARCH=arm CROSS_COMPILE="/home/devendra/gcc-linaro-arm-linux-gnueabihf-2012.05-20120523_linux/bin/arm-linux-gnueabihf-"
u300_defconfig

my cross toolchain is


linux# gcc-linaro-arm-linux-gnueabihf-2012.05-20120523_linux/bin/arm-linux-gnueabihf-gcc
--version

arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-2012.05-20120523 -
Linaro GCC 2012.05) 4.7.1 20120514 (prerelease)


i got the following warnings,



root@devendra:/home/devendra/linux# make ARCH=arm
CROSS_COMPILE="/home/devendra/gcc-linaro-arm-linux-gnueabihf-2012.05-20120523_linux/bin/arm-linux-gnueabihf-"

-fcall-saved-r9 -fcall-saved-r10 -fcall-saved-r11' invalid for
ARCH_HWEIGHT_CFLAGS


i m not sure whether this is a compiler issue or a real warning.

Thanks,
Devendra.
