The __NSIG_WORDS value is based on minimum number of words to hold the maximum number of signals supported by the architecture. This patch also adds __NSIG_BYTES, which is the number of bytes required to represent the supported number of signals. It is used in syscalls which takes a sigset_t. Checked on x86_64-linux-gnu and i686-linux-gnu. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
