Peter Zijlstra f2c4db1bd8 x86/cpu: Sanitize FAM6_ATOM naming
Going primarily by:

  https://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors

with additional information gleaned from other related pages; notably:

 - Bonnell shrink was called Saltwell
 - Moorefield is the Merriefield refresh which makes it Airmont

The general naming scheme is: FAM6_ATOM_UARCH_SOCTYPE

  for i in `git grep -l FAM6_ATOM` ; do
	sed -i  -e 's/ATOM_PINEVIEW/ATOM_BONNELL/g'		\
		-e 's/ATOM_LINCROFT/ATOM_BONNELL_MID/'		\
		-e 's/ATOM_PENWELL/ATOM_SALTWELL_MID/g'		\
		-e 's/ATOM_CLOVERVIEW/ATOM_SALTWELL_TABLET/g'	\
		-e 's/ATOM_CEDARVIEW/ATOM_SALTWELL/g'		\
		-e 's/ATOM_SILVERMONT1/ATOM_SILVERMONT/g'	\
		-e 's/ATOM_SILVERMONT2/ATOM_SILVERMONT_X/g'	\
		-e 's/ATOM_MERRIFIELD/ATOM_SILVERMONT_MID/g'	\
		-e 's/ATOM_MOOREFIELD/ATOM_AIRMONT_MID/g'	\
		-e 's/ATOM_DENVERTON/ATOM_GOLDMONT_X/g'		\
		-e 's/ATOM_GEMINI_LAKE/ATOM_GOLDMONT_PLUS/g' ${i}
  done
