Peter Anvin" Cc: linux-kernel@vger.kernel.org, kvm@vger.kernel.org Subject: [PATCH 0/2] x86 FPU API Date: Sun, 2 May 2010 17:53:56 +0300 Message-Id: <1272812038-32484-1-git-send-email-avi@redhat.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Currently all fpu accessors are wedded to task_struct. However kvm also uses the fpu in a different context. Introduce an FPU API, and replace the current uses with the new API. While this patchset is oriented towards deeper changes, as a first step it simlifies xsave for kvm.
