    x86, msr: msrs_alloc/free for CONFIG_SMP=n · 6ede31e0

    Randy Dunlap reported the following build error:
    
    "When CONFIG_SMP=n, CONFIG_X86_MSR=m:
    
    ERROR: "msrs_free" [drivers/edac/amd64_edac_mod.ko] undefined!
    ERROR: "msrs_alloc" [drivers/edac/amd64_edac_mod.ko] undefined!"
    
    This is due to the fact that <arch/x86/lib/msr.c> is conditioned on
    CONFIG_SMP and in the UP case we have only the stubs in the header.
    Fork off SMP functionality into a new file (msr-smp.c) and build
    msrs_{alloc,free} unconditionally.
