ARM: move shared uprobe/kprobe definitions into new include file Separate the kprobe-only definitions from the definitions needed by both kprobes and uprobes. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>

ARM: Make the kprobes condition_check symbol names more generic In preparation for sharing the ARM kprobes instruction interpreting code with uprobes, make the symbols names less kprobes-specific. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>

ARM: Move generic arm instruction parsing code to new files for sharing between features Move the arm version of the kprobes instruction parsing code into more generic files from where it can be used by uprobes and possibly other subsystems. The symbol names will be made more generic in a subsequent part of this patchset. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>

ARM: Make arch_specific_insn a define for new arch_probes_insn structure Because the common underlying code for ARM kprobes and uprobes needs to share a common architecrure-specific context structure, and because the generic kprobes include file insists on defining this to a dummy structure when kprobes is not configured, a new common structure is required which can exist when uprobes is configured without kprobes. In this case kprobes will define a dummy structure, but without the define aliasing the two structure tags it will not affect uprobes and the shared probes code. Signed-off-by: David A.
