Subject: [PATCH 5/5] x86-32: Don't set ignore_fpu_irq in simd exception
Date: Thu, 18 Mar 2010 14:20:53 -0400 [thread overview]
Message-ID: <1268936453-3727-6-git-send-email-brgerst@gmail.com> (raw)
In-Reply-To: <1268936453-3727-1-git-send-email-brgerst@gmail.com>
Any processor that supports simd will have an internal fpu, and the
irq13 handler will not be enabled.
