Adrian Hunter ec1891afae perf machine: Record if a arch has a single user/kernel address space ... Some architectures have a single address space for kernel and user addresses, which makes it possible to determine if an address is in kernel space or user space. Some don't, e.g.: sparc. Cache that info in perf_env so that, for instance, code needing to fallback failed symbol lookups at the kernel space in single address space arches can lookup at userspace.
