x86/cpu: Sanitize FAM6_ATOM naming

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

CVE-2018-12127
CVE-2018-12130

(backported from commit f2c4db1bd80720cd8cb2a5aa220d9bc9f374f04e)
[tyhicks: Backport to 4.15:
 - arch/x86/kernel/cpu/intel_rdt_pseudo_lock.c doesn't yet exist
 - arch/x86/kernel/tsc_msr.c doesn't use any FAM6_ATOM macros because it
   is missing commit 397d3ad18dc4
 - sound/soc/intel/boards/bytcr_rt5651.c doesn't use any FAM6_ATOM
   macros because it is missing commit fbea16dbc0a3
 - The FAM6_ATOM items in the intel_pstate_cpu_ids[] array use bxt_funcs
   due to missing commit dbd49b85eec7
 - Context change in process_cpuid() because SKYLAKE_X and ATOM_DENVERTON
   share a case block due to missing commit 733ef0f8e76e
 - Manually ran the for loop documented in the commit message to ensure
   that there were no additional uses of the old macros]
