2014-03-18	ARM: Make arch_specific_insn a define for new arch_probes_insn structure	David A. Long
	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.

2014-03-18	ARM: Add an emulate flag to the kprobes/uprobes instruction decode functions	David A. Long
	Add an emulate flag into the instruction interpreter, primarily for uprobes support. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
2014-03-18	ARM: Change the remaining shared kprobes/uprobes symbols to something generic	David A. Long
	Any more ARM kprobes/uprobes symbols which have "kprobe" in the name must be changed to the more generic "probes" or other non-kprobes specific symbol. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
2014-03-18	ARM: Rename the shared kprobes/uprobe return value enum	David A. Long
	Change the name of kprobes_insn to probes_insn so it can be shared between kprobes and uprobes without confusion. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
2014-03-18	ARM: Change more ARM kprobes symbol names to something more generic	David A. Long
	Change kprobe_emulate_none, kprobe_simulate_nop, and arm_kprobe_decode_init function names to something more appropriate for code being shared outside of the kprobes subsystem. Also, move the new arm_probes_decode_init declaration out of the kprobes.h include file and into the probes.h include file. Signed-off-by: David A.

2014-03-18	ARM: Make the kprobes condition_check symbol names more generic	David A. Long
	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>
2014-03-18	ARM: Remove use of struct kprobe from generic probes code	David A. Long
	Change the generic ARM probes code to pass in the opcode and architecture-specific structure separately instead of using struct kprobe, so we do not pollute code being used only for uprobes or other non-kprobes instruction interpretation.

2014-03-18	ARM: use a function table for determining instruction interpreter action	David A. Long
	Make the instruction interpreter call back to semantic action functions through a function pointer array provided by the invoker. The interpreter decodes the instructions into groups and uses the group number to index into the supplied array. kprobes and uprobes code will each supply their own array of functions.

2014-03-18	ARM: Move generic arm instruction parsing code to new files for sharing ↵	David A. Long
	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>
