x86, msr: msrs_alloc/free for CONFIG_SMP=n
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. Reported-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: H.
