Irwin" , Steven Rostedt Subject: [RFC PATCH 02/11] Add fastcall to do_IRQ for i386 Content-Disposition: inline; filename=mcount-fix-i386-do_irq.patch Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org MCOUNT will disable the regparm parameters of the i386 compile options. When doing so, this breaks the prototype of do_IRQ where the fastcall must be explicitly called. Also fixed some whitespace damage in the call to do_IRQ.
