Sparse reports this issue core.c: note: in included file: core.h:239:12: warning: symbol 'pmc_lpm_modes' was not declared. Should it be static? Global variables should not be defined in headers. This only works because core.h is only included by core.c. Single file use variables should be static, so change its storage-class specifier to static.
