Message-Id: <1406020499-5537-3-git-send-email-takahiro.akashi@linaro.org> Date: Tue, 22 Jul 2014 18:14:58 +0900 From: AKASHI Takahiro <takahiro.akashi@...aro.org> To: wad@...omium.org, catalin.marinas@....com, will.deacon@....com, keescook@...omium.org Cc: dsaxena@...aro.org, linux-arm-kernel@...ts.infradead.org, linaro-kernel@...ts.linaro.org, linux-kernel@...r.kernel.org, AKASHI Takahiro <takahiro.akashi@...aro.org> Subject: [PATCH v5 2/3] asm-generic: Add generic seccomp.h for secure computing mode 1 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.
