    alpha: add support for memset16 · 92ce4c3e
    Matthew Wilcox authored
    Alpha already had an optimised fill-memory-with-16-bit-quantity
    assembler routine called memsetw().  It has a slightly different calling
    convention from memset16() in that it takes a byte count, not a count of
    words.  That's the same convention used by ARM's __memset routines, so
    rename Alpha's routine to match and add a memset16() wrapper around it.
    Then convert Alpha's scr_memsetw() to call memset16() instead of
    memsetw().
