Message-Id: <1413387506-5269-1-git-send-email-jarkko.sakkinen@linux.intel.com> Date: Wed, 15 Oct 2014 17:38:26 +0200 From: Jarkko Sakkinen <jarkko.sakkinen@...ux.intel.com> To: Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, "H. Peter Anvin" <hpa@...or.com> Cc: x86@...nel.org, linux-kernel@...r.kernel.org, Jarkko Sakkinen <jarkko.sakkinen@...ux.intel.com> Subject: [PATCH] arch/x86/realmode: make trampoline code conditional for x86-32 Trampoline code is only needed for SMP and in x86-64 for wakeup code. Make it conditional in order to minimize the kernel size.
