  SVN rev 209483 on 2010-06-23 20:44:07Z by kib
  
  Clear DF bit in eflags/rflags on the kernel entry. The i386 and amd64
  ABI specifies the DF should be zero, and newer compilers do not clear
  DF before using DF-sensitive instructions.
  
  The DF clearing for signal handlers was done some time ago.
