      sig 0x000406e3, pf_mask 0xc0, 2017-04-09, rev 0x00ba, size 98304
      sig 0x000406f1, pf_mask 0xef, 2017-03-01, rev 0xb000021, size 26624
      sig 0x000506e3, pf_mask 0x36, 2017-04-09, rev 0x00ba, size 98304
    + This release fixes undisclosed errata on the desktop, mobile and
      server processor models from the Haswell, Broadwell, and Skylake
      families, including even the high-end multi-socket server Xeons
    + Likely fix the TSC-Deadline LAPIC errata (BDF89, SKL142 and
      similar) on several processor families
    + Fix erratum BDF90 on Xeon E7v4, E5v4(?) (closes: #862606)
    + Likely fix serious or critical Skylake errata: SKL138/144,
      SKL137/145, SLK149
    * Likely fix nightmare-level Skylake erratum SKL150.  Fortunately,
      either this erratum is very-low-hitting, or gcc/clang/icc/msvc
      won't usually issue the affected opcode pattern and it ends up
      being rare.
      SKL150 - Short loops using both the AH/BH/CH/DH registers and
      the corresponding wide register *may* result in unpredictable
      system behavior.  Requires both logical processors of the same
      core (i.e. sibling hyperthreads) to be active to trigger, as
      well as a "complex set of micro-architectural conditions"
  * source: remove unneeded intel-ucode/ directory
    Since release 20170511, upstream ships the microcodes both in .dat
    format, and as Linux-style split /lib/firmware/intel-ucode files.
    It is simpler to just use the .dat format file for now, so remove
    the intel-ucode/ directory. Note: before removal, it was verified
    that there were no discrepancies between the two microcode sets
    (.dat and intel-ucode/)
  * source: remove superseded upstream data file: 20161104
