Subject: [PATCH 4/4] x86-32: Don't set ignore_fpu_irq in simd exception
Date: Sun, 21 Mar 2010 09:00:46 -0400 [thread overview]
Message-ID: <1269176446-2489-5-git-send-email-brgerst@gmail.com> (raw)
In-Reply-To: <1269176446-2489-1-git-send-email-brgerst@gmail.com>
Any processor that supports simd will have an internal fpu, and the
irq13 handler will not be enabled.
