Subject: [2/4] [2.6 patch] better i386 CPU selection
Date: Sun, 14 Sep 2003 00:27:52 +0200	[thread overview]
Message-ID: <20030913222751.GP27368@fs.tum.de> (raw)
In-Reply-To: <20030913222443.GN27368@fs.tum.de>

- move "struct movsl_mask movsl_mask" to usercopy.c
  (CONFIG_X86_INTEL_USERCOPY is used on non-Intel CPUs)
