ARM: 7181/1: Restrict kprobes probing SWP instructions to ARMv5 and below The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.

ARM: 7180/1: Change kprobes testcase with unpredictable STRD instruction There is a kprobes testcase for the instruction "strd r2, [r3], r4". This has unpredictable behaviour as it uses r3 for register writeback addressing and also stores it to memory. On a cortex A9, this testcase would fail because the instruction writes the updated value of r3 to memory, whereas the kprobes emulation code writes the original value. Fix this by changing testcase to used r5 instead of r3.
