s390/kprobes: use static buffer for insn_page
With a relocatable kernel that could reside at any place in memory, the current logic for allocating a kprobes insn_page does not work. The GFP_DMA allocated buffer might be more than 2 GB away from the kernel. Use a static buffer for the insn_page instead.
