New revision: 295148
URL: https://svnweb.freebsd.org/changeset/base/295148

Log:
  MFC r294311:
  Clear whole XMM register file instead of only XMM0.  Also clear x87
  registers.  This brings amd64 on par with i386, providing consistent
  initial FPU state.

  PR:   206370

  MFC r294312:
  Use ANSI definitions.  Wrap long line.

  MFC r294313:
  Adjust i386 comment to match amd64 one after r294311.

  Approved by:  re (gjb)
