Currently unwind_next_frame_record() has an optional callback to convert the address space of the FP. This is necessary for the NVHE unwinder, which tracks the stacks in the hyp VA space, but accesses the frame records in the kernel VA space. This is a bit unfortunate since it clutters unwind_next_frame_record(), which will get in the way of future rework. Instead, this patch changes the NVHE unwinder to track the stacks in the kernel's VA space and translate to FP prior to calling unwind_next_frame_record(). This removes the need for the translate_fp() callback, as all unwinders consistently track stacks in the native address space of the unwinder. At the same time, this patch consolidates the generation of the stack addresses behind the stackinfo_get_*() helpers.
