From d8bf616be5f05b955d3ee32ad92d4cdb87e30349 Mon Sep 17 00:00:00 2001 From: Firoz Khan Date: Tue, 13 Nov 2018 15:01:50 +0530 Subject: [PATCH] alpha: remove CONFIG_OSF4_COMPAT flag from syscall table Remove CONFIG_OSF4_COMPAT config flag from system call table - systbls.S and to keep the same feature, add the flag in osf_sys.c. One of the patch in this patch series will generate the system call table file. In order to come up with a common implementation across all architecture, we need this change.
