Merge tag 'alpha-fixes-v7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha

Pull alpha floating point emulation fix from Matt Turner:
 "Make the FP emulation determine tininess after rounding, as the
  hardware does.

  soft-fp always determined it before rounding, so an operation that
  trapped for software completion could report an underflow the same
  operation would not report when it did not trap. glibc's math
  testsuite catches the disagreement.

  This adds _FP_TININESS_AFTER_ROUNDING to the shared soft-fp code in
  include/math-emu/, as glibc's copy already has, and sets it only for
  alpha. It defaults to zero, so powerpc, sh and sparc are unchanged.

  This is the last patch of a three-patch series; the first two were
  merged for v7.3"
