Sometimes we want the kernel build process to only print messages on errors, e.g. in automated build testing. This uses the "kecho" macro that the build system provides to hide a few informational messages. Nothing changes for a regular "make" or "make V=1". Without this patch, building any ARM kernel results in: Kernel: arch/arm/boot/Image is ready Kernel: arch/arm/boot/zImage is ready Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Nicolas Pitre <nicolas.pitre@linaro.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Michal Marek <mmarek@suse.cz>
