Subject: [PATCH] Fix hardcoded value in vsyscall.lds
Date: Sat, 28 Aug 2004 12:01:56 -0400 [thread overview]
Message-ID: <4130AC74.8010600@quark.didntduck.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 171 bytes --]
The last attempt to clean this up still left a hardcoded constant (the
offset from __FIXADDR_TOP). This patch moves VSYSCALL_BASE to
asm-offsets.c.
