From dab10731da65a0deba46402ca9fadf6974676cc8 Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Thu, 4 Sep 2014 15:34:14 +0100 Subject: [PATCH] asm-generic: add generic seccomp.h for secure computing mode 1 Note: This patch is from v6 of Takahiro's proposed "arm64: add seccomp support" patchset (leecam@google.com) Those values (__NR_seccomp_*) are used solely in secure_computing() to identify mode 1 system calls. If compat system calls have different syscall numbers, asm/seccomp.h may override them.
