From 303395ac3bf3e2cb488435537d416bc840438fcb Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 11 Nov 2011 16:07:41 -0800 Subject: x86: Generate system call tables and unistd_*.h from tables Generate system call tables and unistd_*.h automatically from the tables in arch/x86/syscalls. All other information, like NR_syscalls, is auto-generated, some of which is in asm-offsets_*.c. This allows us to keep all the system call information in one place, and allows for kernel space and user space to see different information; this is currently used for the ia32 system call numbers when building the 64-bit kernel, but will be used by the x32 ABI in the near future. This also removes some gratuitious differences between i386, x86-64 and ia32; in particular, now all system call tables are generated with the same mechanism. Cc: H. J.
