Date: Fri, 22 Mar 2013 18:24:57 -0700 From: Andi Kleen <andi@...stfloor.org> To: linux-kernel@...r.kernel.org Cc: torvalds@...ux-foundation.org, akpm@...ux-foundation.org, x86@...nel.org, Andi Kleen <ak@...ux.intel.com> Subject: [PATCH 03/29] tsx: Add generic disable_txn macros From: Andi Kleen <ak@...ux.intel.com> Add generic macros to disable transactions per process. Without TSX (or other HTM) support this is a noop. An RTM enabled x86 kernel uses its own version.
