From 41d4d22399119f11bbdfa5d460a7270412029eb7 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 7 Mar 2003 18:37:10 +0000 Subject: Update. * sysdeps/i386/i486/bits/atomic.h: Fix a few unused definitions. * sysdeps/unix/sysv/linux/i386/lowlevellock.h: Remove all trace of lll_wake_tid. This was used only to work around kernel limits in the early days. * sysdeps/unix/sysv/linux/s390/lowlevellock.h: Likewise. * sysdeps/unix/sysv/linux/sh/libc-lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/sh/lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/sh/lowlevellock.h: Likewise. --- nptl/ChangeLog | 10 ++++++++++ nptl/sysdeps/unix/sysv/linux/i386/lowlevellock.h | 16 +--------------- nptl/sysdeps/unix/sysv/linux/s390/lowlevellock.h | 10 ---------- nptl/sysdeps/unix/sysv/linux/sh/libc-lowlevellock.S | 19 +------------------ nptl/sysdeps/unix/sysv/linux/sh/lowlevellock.S | 21 +-------------------- nptl/sysdeps/unix/sysv/linux/sh/lowlevellock.h | 8 -------- 6 files changed, 13 insertions(+), 71 deletions(-) (limited to 'nptl') diff --git a/nptl/ChangeLog b/nptl/ChangeLog index 3ad0d2eb9a..562e38bffd 100644 --- a/nptl/ChangeLog +++ b/nptl/ChangeLog @@ -1,5 +1,15 @@ 2003-03-07 Ulrich Drepper + * sysdeps/i386/i486/bits/atomic.h: Fix a few unused definitions. + + * sysdeps/unix/sysv/linux/i386/lowlevellock.h: Remove all trace of + lll_wake_tid.
