From f4e1f1b1379df5b44fffbf09940761921d35da66 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 10 Nov 2025 19:54:39 +0100 Subject: [PATCH] s390/syscalls: Remove system call table pointer from thread_struct With compat support gone there is only one system call table left. Therefore remove the sys_call_table pointer from thread_struct and use the sys_call_table directly.
