In discussion on LKML (https://lkml.org/lkml/2014/11/28/158), Russell
King suggest to move all probe related code to arch/arm/probes. This
patch do the work. Due to dependency on 'arch/arm/kernel/patch.h', this
patch also move patch.h to 'arch/arm/include/asm/patch.h', and related
'#include' directive are also midified to '#include <asm/patch.h>'.

Moving is good to me, but renaming files are also required I think.

As I did on x86, these would be better renamed as expressing what they do.
I guess most of the files may have emulate-*.c or decode-*.c :)

Thank you,

OK. I posted another patch in this thread. The directory tree is as follow:

arch/arm/probes/
|-- Makefile
|-- decode-arm.c
|-- decode-arm.h
|-- decode-thumb.c
|-- decode-thumb.h
|-- decode.c
|-- decode.h
|-- kprobes
|   |-- actions-arm.c
|   |-- actions-common.c
|   |-- actions-thumb.c
|   |-- kprobes.c
|   |-- kprobes.h
|   |-- test-arm.c
|   |-- test-core.c
|   |-- test-core.h
|   `-- test-thumb.c
`-- uprobes
    |-- actions-arm.c
    |-- uprobes.c
    `-- uprobes.h

2 directories, 19 files

What do you think?

Yeah, that looks better :)

Btw, if you introduce probes/{kprobes,uprobes}/, *probes.c should be core.c too,
since the directories already show its name. And also, both dirs should have its
own Makefile.

Thank you,
