From b5e8b733a18a1192666005f95f44e02440b057d4 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Tue, 22 May 2007 17:38:26 +0200 Subject: [PATCH] [PARISC] Disable LWS debugging The LWS debugging code on parisc is wrongly enabled due to a bug in the use of the preprocessor directives. This debugging code is not thread safe and causes problems with a recent glibc on SMP kernels.
