Subject: [PATCH 0/8] RFC x86: Generate system calls from a simple table
Date: Thu, 17 Nov 2011 14:37:18 -0800	[thread overview]
Message-ID: <1321569446-20433-1-git-send-email-hpa@linux.intel.com> (raw)

From: "H. Peter Anvin" <hpa@linux.intel.com>

This patch series generates all the files that depend on the x86
system call numbers -- specifically unistd_*.h and the system call
tables themselves -- from a simple text file table.  Furthermore, it
unifies the multiple different ways that the system call tables are
generated.  Although this is an x86-specific patch, the scripts are
intended to be generic enough that it should be easy for other
architectures to use them as well.

The "ABI" column in the text file is currently unused, however, it is
intended to support the new x32 ABI, and may be helpful for other
architectures that have multiple system call ABI ranges as well.

Special thanks to David Woodhouse, Michal Marek and Sam Ravnborg for
helping me straight out the maze of Kbuild dependencies.
