47e190fafd ARM: Change the remaining shared kprobes/uprobes symbols to something generic
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.

eb73ea97e6 ARM: Change more ARM kprobes symbol names to something more generic
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.

f145d664df 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.

7579f4b376 ARM: Remove use of struct kprobe from generic probes code
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.

3e6cd394bb ARM: use a function table for determining instruction interpreter action
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.

c18377c303 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.
