[S390] compile fix for latest binutils (88381011) · Commits · e / devices / android_kernel_fairphone_FP3

The latest binutils won't accept the stfl instruction with march=g5 which is the correct behaviour. Unfortunately head.S is assembled with -march=g5 even if the target cpu is z900 or later. To get 31-bit kernels compiled again the easiest fix is to use the .insn notation for the stfl instruction in head.S. Signed-off-by:
