From: "David A. Long" <dave.long@linaro.org>
This patch series adds basic uprobes support to ARM. It is based on patches developed earlier by Rabin Vincent. That approach of adding hooks into the kprobes instruction parsing code was not well received. This approach separates the ARM instruction parsing code in kprobes out into a separate set of functions which can be used by both kprobes and uprobes. Both kprobes and uprobes then provide their own semantic action tables to process the results of the parsing.
The following are noteworthy changes made for v3:
1) The ARM uprobes functionality no longer depends on kprobes. As a side effect of this there are no longer any changes to the common kprobes include file (or any other common kprobes files). 2) A couple large patches have been broken down into more smaller patches. 3) A problem with uretprobes has been fixed. 4) The kprobes-test module has been made more useable for thumb tests. 5) The argument list to the "action" functions has been shrunk. 6) Alignment with a few recent patches that were made to common uprobes code specifically to support this patchset.
This patchset is based on v3.13-rc1
David A. Long (14): uprobes: allow ignoring of probe hits ARM: move shared uprobe/kprobe definitions into new include file ARM: Move generic arm instruction parsing code to new files for sharing between features ARM: move generic thumb instruction parsing code to new files for use by other feature ARM: use a function table for determining instruction interpreter actions ARM: Remove use of struct kprobe from generic probes code ARM: Use new opcode type in ARM kprobes/uprobes code ARM: Make the kprobes condition_check symbol names more generic ARM: Change more ARM kprobes symbol names to something more ARM: Rename the shared kprobes/uprobe return value enum ARM: Change the remaining shared kprobes/uprobes symbols to something generic ARM: Add an emulate flag to the kprobes/uprobes instruction decode functions ARM: add uprobes support ARM: Remove uprobes dependency on kprobes
