Martin Schwidefsky d7f56ee119 s390/ptrace: Preserve previous registers for short regset write ... commit 9dce990d2c upstream. Ensure that if userspace supplies insufficient data to PTRACE_SETREGSET to fill all the registers, the thread's old registers are preserved. convert_vx_to_fp() is adapted to handle only a specified number of registers rather than unconditionally handling all of them: other callers of this function are adapted appropriately. Based on an initial patch by Dave Martin.
