Subject: s390/seccomp: fix error return for filtered system calls
From: Jan Willeke <willeke@de.ibm.com>
commit dc295880c6752076f8b94ba3885d0bfff09e3e82 upstream.
The syscall_set_return_value function of s390 negates the error argument
before storing the value to the return register gpr2. This is incorrect,
the seccomp code already passes the negative error value.
Store the unmodified error value to gpr2.
