commit 1b17cb796f5d40ffa239c6926385abd83a77a49b Author: Martin Schwidefsky <[email protected]> Date: Fri Feb 19 15:29:05 2016 +0100 s390/fpu: signals vs. floating point control register git commit 904818e2f229f3d94ec95f6932a6358c81e73d78 "s390/kernel: introduce fpu-internal.h with fpu helper functions" introduced the fpregs_store / fp_regs_load helper. These function fail to save and restore the floating pointer control registers. The effect is that the FPC is not correctly handled on signal delivery and signal return.
