Alexander Shishkin d83212d5dd kallsyms, x86: Export addresses of PTI entry trampolines 
Currently, the addresses of PTI entry trampolines are not exported to
user space. Kernel profiling tools need these addresses to identify the
kernel code, so add a symbol and address for each CPU's PTI entry
trampoline.
