From 5e249d4528528c9a77da051a89ec7f99d31b83eb Mon Sep 17 00:00:00 2001 From: "Suzuki K. Poulose" Date: Mon, 7 Jan 2013 00:26:57 +0000 Subject: uprobes/powerpc: Add dependency on single step emulation 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.
