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 v6:
1) Put back the "const" type modifier in decode table usage. 2) Made t16_decode_pop() static again. 3) Merged the last patch back into the previous patch, to avoid needlessly introducing a uprobes dependency on kprobes in Kconfig. 4) Added a signed-off From rabin, and ack's from Tixy.
David A. Long (13): 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 action ARM: Remove use of struct kprobe from generic probes 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: Make arch_specific_insn a define for new arch_probes_insn structure ARM: add uprobes support
