3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: "Suzuki K. Poulose" <[email protected]> commit 5e249d4528528c9a77da051a89ec7f99d31b83eb upstream. Uprobes uses emulate_step in sstep.c, but we haven't explicitly specified the dependency. On pseries HAVE_HW_BREAKPOINT protects us, but 44x has no such luxury. Consolidate other users that depend on sstep and create a new config option. Signed-off-by: Ananth N Mavinakayanahalli <[email protected]> Signed-off-by: Suzuki K.
