Mike Rapoport (Microsoft) 36de1e4238 x86/kprobes: enable EXECMEM_ROX_CACHE for kprobes allocations ...

x86::alloc_insn_page() always allocates ROX memory.

Instead of overriding this method, add EXECMEM_KPROBES entry in
execmem_info with pgprot set to PAGE_KERNEL_ROX and use ROX cache when
configuration and CPU features allow it.
