Subject: [PATCH] Immediate Values - i386 Optimization - fix warnings
Date: Sun, 12 Aug 2007 23:23:38 -0400	[thread overview]
Message-ID: <20070813032338.GA21363@Krystal> (raw)
In-Reply-To: <20070812150815.600419531@polymtl.ca>

Immediate Values - i386 optimization - fix warnings

2 warnings creps in caused by my recent work with text lock edit.

arch/i386/kernel/immediate.c: In function 'arch_immediate_update':
arch/i386/kernel/immediate.c:228: warning: passing argument 1 of '__constant_memcpy' makes pointer from integer without a cast
arch/i386/kernel/immediate.c:228: warning: passing argument 1 of '__memcpy' makes pointer from integer without a cast
arch/i386/kernel/immediate.c:185: warning: unused variable 'bypass_immediate'

This trivial patch fixes this issue.
