From a60f7b69d92c0142c80a30d669a76b617b7f6879 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Fri, 29 Jul 2016 09:30:18 -0700 Subject: generic syscalls: Wire up memory protection keys syscalls These new syscalls are implemented as generic code, so enable them for architectures like arm64 which use the generic syscall table. According to Arnd: Even if the support is x86 specific for the forseeable future, it may be good to reserve the number just in case. The other architecture specific syscall lists are usually left to the individual arch maintainers, most a lot of the newer architectures share this table.
