* Merge branch 'uprobes-v7' of git://git.linaro.org/people/dave.long/linux ↵Russell King2014-03-1966-2754/+3700
|\ | | | | | | | | | | | | | | | | | | | | | | into devel-stable 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.
| * ARM: add uprobes supportDavid A. Long2014-03-189-1/+542
| | | | | | | | | | | | | | | | | | | | | | | | Using Rabin Vincent's ARM uprobes patches as a base, enable uprobes support on ARM. Caveats: - Thumb is not supported Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: David A. Long <dave.long@linaro.org>
| * ARM: Make arch_specific_insn a define for new arch_probes_insn structureDavid A. Long2014-03-1812-82/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 more ARM kprobes symbol names to something more genericDavid A. Long2014-03-186-19/+19
| | | | | | | | | | | | | | | | | | | | 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.

| * ARM: use a function table for determining instruction interpreter actionDavid A. Long2014-03-1811-271/+441
| | | | | | | | | | | | | | | | | | | | | | 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.

The code assumed that a CPU entering idle would actually be powered off, loosing its state entierely, and would then need to be reinitialized. It turns out that this is not always the case, and some HW performs CPU PM without actually killing the core. In this case, we try to reinitialize KVM while it is still live. It ends up badly, as reported by Andre Przywara (using a Calxeda Midway): [ 3.663897] Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x685760 [ 3.663897] unexpected data abort in Hyp mode at: 0xc067d150 [ 3.663897] unexpected HVC/SVC trap in Hyp mode at: 0xc0901dd0 The trick here is to detect if we've been through a full re-init or not by looking at HVBAR (VBAR_EL2 on arm64). This involves implementing the backend for __hyp_get_vectors in the main KVM HYP code (rather small), and checking the return value against the default one when the CPU notifier is called on CPU_PM_EXIT.

However this does not happen if generic MTD_NAND framework is built as module (CONFIG_MTD_NAND=m). Therefore, when MTD/NAND and MTD/NAND/OMAP2 modules are loaded, they are unable to find any matching platform_device and remain un-binded. This causes on board NAND flash to remain un-detected.

There is code in the regulator core to deal with situations where no regulator is specified and provide a dummy, but that works on DT-based boards only. The situation can be remedied by adding a dummy regulator during board initialization.
