From: Andy Lutomirski commit bb5fe2f78eadf5a52d8dcbf9a57728fd107af97b Author: Andy Lutomirski Date: Sun Jun 5 13:50:22 2011 -0400 x86-64: Remove vsyscall number 3 (venosys) It just segfaults since April 2008 (a4928cff), so I'm pretty sure that nothing uses it. And having an empty section makes the linker script a bit fragile.
