cpumask: use modern cpumask style in drivers/edac/amd64_edac.c
cpumask_t -> struct cpumask, and don't put one on the stack. (Note: this is actually on the stack unless CONFIG_CPUMASK_OFFSTACK=y). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
