Jon Medhurst (Tixy) 4cd872d973 ARM: kprobes: Fix unreliable MRS instruction tests 
For the instruction 'mrs Rn, cpsr' the resulting value of Rn can vary due to
external factors we can't control. So get the test code to mask out these
indeterminate bits.

Jon Medhurst (Tixy) 8d257e95a9 ARM: kprobes: Add test cases for stack consuming instructions 
These have extra 'checker' functions associated with them so lets make
sure those get covered by testing. As they may create uninitialised
space on the stack we also update the test code to ensure such space is
consistent between test runs. This is done by disabling interrupts in
setup_test_context().

Wang Nan fca08f326a ARM: probes: move all probe code to dedicate directory 
In discussion on LKML (https://lkml.org/lkml/2014/11/28/158), Russell
King suggests to move all probe related code to arch/arm/probes. This
patch does the work. Due to dependency on 'arch/arm/kernel/patch.h', this
patch also moves patch.h to 'arch/arm/include/asm/patch.h', and related
'#include' directives are also midified to '#include <asm/patch.h>'.

Following is an overview of this patch:
