[PATCH] kprobes: enable funcions only for required arch
Kernel/kprobes.c defines get_insn_slot() and free_insn_slot() which are currently required _only_ for x86_64 and powerpc (which has no-exec support). FYI, get{free}_insn_slot() functions manages the memory page which is mapped as executable, required for instruction emulation. This patch moves those two functions under __ARCH_WANT_KPROBES_INSN_SLOT and defines __ARCH_WANT_KPROBES_INSN_SLOT in arch specific kprobes.h file.
