/*
 * arch/alpha/lib/strncpy.S
 * Contributed by Richard Henderson (rth@tamu.edu)
 *
 * Copy no more than COUNT bytes of the null-terminated string from
 * SRC to DST.  If SRC does not cover all of COUNT, the balance is
 * zeroed.
 *
 * Or, rather, if the kernel cared about that weird ANSI quirk.  This
 * version has cropped that bit o' nastiness as well as assuming that
 * __stxncpy is in range of a branch.
