On s390x syscalls are triggered by svc instruction. One can pass the syscall number encoded in the instruction "svc 123" or by storing it in r1: lghi r1,123 svc 0 If the syscall number is encoded in the instruction, this can cause broken syscall restarts. Therefore this patch is now just passing the syscall number in r1. See also kernel-commit: "s390/signal: switch to using vdso for sigreturn and syscall restart" https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/s390/[%e2%80%a6]call.c?h=v6.0-rc1&id=df29a7440c4b5c65765c8f60396b3b13063e24e9 As information, the "svc 0" feature was introduced in kernel 2.5.62: commit b5aad611393ef2e132e3648fa4c6e56a9cfa8708 |
