ARM: probes: move all probe code to dedicate directory

ARM: probes: fix instruction fetch order with

2014-04-01T13:45:19+00:00

If we are running BE8, the data and instruction endianness do not match, so use to correctly translate memory accesses into ARM instructions. Acked-by: Jon Medhurst Signed-off-by: Ben Dooks [taras.kondratiuk@linaro.org: fixed Thumb instruction fetch order] Signed-off-by: Taras Kondratiuk

ARM: Make arch_specific_insn a define for new arch_probes_insn structure

2014-03-18T20:39:40+00:00

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.

ARM: Change the remaining shared kprobes/uprobes symbols to something generic

2014-03-18T20:39:39+00:00

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 Acked-by: Jon Medhurst

ARM: Rename the shared kprobes/uprobe return value enum

2014-03-18T20:39:38+00:00

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 Acked-by: Jon Medhurst

ARM: Make the kprobes condition_check symbol names more generic

2014-03-18T20:39:37+00:00

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 Acked-by: Jon Medhurst

ARM: Remove use of struct kprobe from generic probes code

2014-03-18T20:39:37+00:00

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. Signed-off-by: David A. Long Acked-by: Jon Medhurst

ARM: use a function table for determining instruction interpreter action

2014-03-18T20:39:36+00:00

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.

ARM: Move generic arm instruction parsing code to new files for sharing between features

2014-03-18T20:39:35+00:00

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 Acked-by: Jon Medhurst

ARM: Fix missing includes in kprobes sources

2014-03-18T20:39:34+00:00

Make sure includes in ARM kprobes sources are done explicitly. Do not rely on includes from other includes. Signed-off-by: David A. Long Acked-by: Jon Medhurst
