[PATCH 00/10] x86: Use the generic math implementations

[H.J. Lu]

The new generic math implementations are faster than the current assembly
versions on i686 and x86-64.  This series of patches replaces the x86
assembly versions with the generic math implementations and enables FMA
for x86-64.

H.J. Lu (10):
  x86-64: Replace assembly versions of e_expf with generic e_expf.c
  i386: Replace assembly versions of e_expf with generic e_expf.c
  x86-64: Add exp2f with FMA
  i386: Replace assembly versions of e_exp2f with generic e_exp2f.c
  i386: Replace assembly versions of e_logf with generic e_logf.c
  x86-64: Add logf with FMA
  x86-64: Add log2f with FMA
  x86-64: Add powf with FMA
  i386: Replace assembly versions of e_log2f with generic e_log2f.c
  i386: Replace assembly versions of e_powf with generic e_powf.c
