s390/linkage: increase asm symbols alignment to 16 Both clang and gcc (for -march=z13 and later) align functions to 16 bytes at -O2 to benefit branch prediction. Make asm symbols alignment consistent with that. This also benefits potential ftrace code patching, which is currently able to patch 8 aligned bytes at once. With defconfig this currently increases .text size by 4104 bytes. Reviewed-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
