[PATCH v2 9/9] ARM: kprobes: Don't HAVE_KPROBES when CONFIG_THUMB2_KERNEL is selected

Currently, the kprobes implementation for ARM only supports
the ARM instruction set, so it only works if
CONFIG_THUMB2_KERNEL is not enabled.

Until kprobes is updated to work with Thumb-2, turning it on
will cause horrible things to happen, so this patch disables it
for now.
